Users

Introduction

This table allows you to input all the users who will use the applications. The number of users does not necessarily have to coincide with the number of licenses.
The number of licenses only limits the number of simultaneous accesses to Clever Suite.

Example

A company that has purchased three licenses can install Clever Suite on more than three computers and the number of users can be greater than three, as long as no more than three designers are working simultaneously at any time.

Table fields

UserName: it is an abbreviation of the user’s full name and may include a maximum of two characters in capital letters.
Name: it is the first name of the user. The first letter is capitalised.
Surname: it is the user's surname. The first letter is capitalised.
Role: designs’ roles within the application can either be admin or user. In a company, there must only be one admin. All other operators must be user. Only the admin can access and modify the configuration options and he is the person responsible for the configuration of Clever Suite.

Logo: here you can insert your company logo, which must have a maximum resolution of 300 x 300 pixels. Pressing the button next to the logo opens a dialogue box that allows you to upload the desired design. If the design does not appear, it means that its resolution is too high and must be reduced.
Currency: you can select the desired currency in the box below.
Deletion Password Company archive: as the deletion of designs from the Company Archive is a critical operation, a password must be entered to proceed with this operation. For security reasons, the following field requires confirmation of the said password.

Electrical parameters

Introduction

Here you can define some parameters that are involved in the electrical calculation or mechanical design, specific to each company.

Default insulating overhang at the side of the foil winding (mm)

Enter the insulator overhang between the coil in the case of foil winding. This value will then be set automatically in the designs. It only applies to foil conductors as the set overhang for strip and wire conductors is always 0.
For all conductor types, it is possible to change the set value throughout the design.

Flat wire insulation thickness (mm)

The flat wire can be enamelled or Nomex insulated. Depending on the type of insulation, the thickness of the insulation changes. Enter the chosen thickness here.

Conductor waste factor

The winding weight can be increased by entering the multiplication factor here. In the technical specification and winding weight calculation, the exact theoretical weight will still be given.

Example

Field	Value
Theoretical conductor weight	10.00 kg
Waste factor	1.03
Weight in the bill of materials and cost	10.30 kg

Core waste factor

The same principle applies to core weight, as above.

Bulging of the windings

Introduction

The bulging of the winding is the multiplicative factor applied to the theoretical winding thickness to reach the actual winding thickness required. This parameter depends on the type of winding machines available in the company and how they work. Generally, in order to determine the bulging coefficient under various conditions, a series of sample windings must be defined. This includes measuring their real thickness and calculating the ratio between the real thickness and that which was theoretically calculated. Establishing the real winding thickness is particularly important as it leads to determining accuracy in the calculation of:

Short-circuit voltage
Load voltage
Losses in the conductors and consequently overtemperature in the various winding sections

Within the table, you can define the bulging coefficient depending on the type, material and thickness of the conductor.
Using the "+" or "-" buttons in the navigator at the top right, you can insert rows to achieve greater granularity or delete rows if required fewer details.

Table Fields (Bulging of the windings)

Coil shape: the code that identifies the shape of the coil can be either rectangular R or cylindrical C. The current applications are not yet designed for cylindrical coils so the content of this field must always be R. Coil diversification will be included in future versions of the applications.
Material: select the material of the winding - AL or CU.
Code: select the type of winding by entering one of the following codes: F = wire P = flat wire B = foil
MAX. thickness: the maximum radial thickness of the conductor for this bulging. If the chosen coefficient of use is applicable for any thickness enter 0. If there is a thickness limitation, enter the thickness limit. In this latter case, enter an additional line for type and/or conductor material without set limitation, i.e. with MAX.thickness = 0 and enter the correct coefficient.
Coefficient: multiplication factor to be applied to the theoretical thickness to obtain the actual thickness.

Construction parameters

Introduction

Under construction parameters, you will find all the tables that define the various design parameters. They can be used to design each type of element in an optimised way.
The PROFESSIONAL version of Clever Suite includes tables with standard values that may be quite different from the proportions you use in your company. Optimisation varies according to financial, geographical, and time-based conditions within which each company operates. Therefore, it is paramount to compare the data supplied with your internal optimisation and carefully evaluate the values to be entered into the applications in order to obtain the best design at the lowest cost for all the various element types and relevant power.
In essence, it is a matter of defining which geometric parameters lead to the greatest advantage in financial terms.
Clever applications will automatically adapt your established geometric parameters and allow you to design elements as optimised as possible straightaway. Of course, any parameters entered automatically by the applications can be changed manually during the design process.

For Clever Transfo and Clever Inductor there are three tables:

for elements built with oriented grain (GO) magnetic sheet and winding directly on the core. This is because in these cases, the proportioning is generally quite different to those in non-oriented grain (NO).
for elements built with the non-oriented grain (NO) magnetic sheet and winding directly on the core
for elements built with the non-oriented grain (NO) magnetic sheet and winding on the bobbin

For Clever Small T and Clever Small I there are two tables:

Generic elements for standard elements
UL elements (which must comply with UL standards).

Other tables, to define different parameters for special constructions, can be inserted on request.
All dimensions in the tables are expressed in mm. unless explicitly stated.

Material tables

Introduction

The tables in this section are named 'technical tables' and contain all the materials that are used in the construction of the designed elements. There is a technical table for each group of materials. As illustrated in the forthcoming, the electrical and/or dimensional data required for the component being designed must be entered in these tables. If there are different sub-families within a table, they must be identified by a code. When choosing the code, follow the instructions in the help section of the specific table. Finally, you must enter the article code that you use in your management system. Bear in mind that the list of materials in your warehouse is imported onto Clever Suite and can be found under "Material cost". The article code from the technical tables will allow applications to find the component on the imported list under "Material cost", thus retrieving your official description and its cost. These will be used at the design stage to compile the bill of materials and to calculate the total cost of materials.
In the initial installation, the tables are pre-filled with materials that we consider standard. This will shorten your data entry work and provide an example of how to enter the data. However, you can subsequently edit, delete, and add rows as you require. It is important to carry out the configuration phase thoroughly as it will determine the quality of your future work.

Threaded rods

Introduction

Threaded rods are used in Clever Transfo and Clever Inductor applications for horizontal and vertical clamping of elements. The material is, generally, galvanized steel.

Table fields (Threaded rods)

Multi wire cables

Introduction

Cables are either class B or F or H insulated multi-wire conductors that can be used as the output terminals of a shield (in which case they will be yellow/green). They may also used in small wire coils, welded to the conductors to connect the terminal blocks. In the latter case, the external insulation will be made of different materials depending on the temperature class and may have different colours to comply with the colour codes defined by the company.

Table fields (multi wire cables)

Rating current A: it is the maximum current allowed.
External diameter: external diameter - usually available from suppliers' tables. This is not mandatory, it can also be omitted.
Insulating voltage KV: maximum insulation voltage admitted for the cable. The applications compare this value with the insulation voltage of the element.
Code: this coding is used to distinguish the type of insulation. LSIL = Silicone is the standard. For other materials, additional codes must be defined but must be recognised by the design rule that selects the cable and enters it in the bill of materials. Hence, we require the definition of other codes in the customisation phase of the application.
Material: material abbreviation. By opening the drop-down menu of the Material field you see the list of all available materials and can choose the correct abbreviation.
Section mm2: conductor section. This information is mandatory.

Axial dim: for wire, enter the bare diameter, for flat wire or foil enter the axial dimension.
Radial dim: for wire, enter the insulated diameter, for flat wire or foil enter the radial dimension.
Section mm2: enter the net section, ideally from the supplier's table. If this is not possible, for flat wire, the net section is calculated as follows:
1. Case radial thickness <= 2.24
  Section = (axial dimension x radial dimension) - 0.363
2. Case radial thickness case > 2.24
  Section = (Axial dimension x Radial dimension) - 0.55
However, for wire and foil, the precise area is calculated.
Kg/meter: we recommend taking this parameter from the supplier's tables. Otherwise, it should be calculated from the section and specific weight (CU = 8.90 kg/dm3 AL = 2.70 kg/dm3).
R/meter Ohm: we recommend obtaining this parameter from the supplier's tables. Otherwise, it should be calculated from the section and specific resistance (CU = 0,00175 Ω/m AL = 0 ,0028 Ω/m).
Code: this code defines both type and material of the conductor. Enter:

Code	Material
B3	AL foil
B4	CU foil
P3	AL flat wire
P4	CU flat wire
F3	AL wire
F4	CU wire

Article: To select the material, use the article code of your management system. This value will allow the applications to retrieve the description and unit cost into the table Material Cost by importing the list of materials available in your warehouse.

Design rules

Introduction

In this section, you will find the design rules that have been set in the parameters. Specifically, tables where dimensional values are defined according to different electrical or mechanical parameters.

Winding insulation

Introduction

This table defines the total thickness of the insulation layer to be interposed between the windings according to the maximum insulation voltage admitted. The applications use the type and thickness of the interlayer insulation and calculate the number of turns required to reach the thickness given in the table. If there were no interlayers, applications would use a default material depending on the temperature class - a thickness between 0.18 and 0.25, depending on the standard thicknesses available.

Table fields (Winding insulation)

Total insulation thickness: required insulation thickness.
U insulation KV: maximum insulation voltage.

Default isolation definition

Introduction

This table defines the default insulation material and thickness, which it uses as insulation between core and coil and between windings, when the designer has not defined any interlayer insulation. The choice depends on the temperature class chosen.
Otherwise, however, i.e. if the designer has defined the interlayer insulation in some windings, the applications will ensure that the insulation between windings and between core and coil are equal to that of the interlayers.
Using this table you can modify the default data by inserting those that best match your design rules.

Carpentry details

Introduction

This is a measure/value table that allows you to enter, for a specified carpentry, each component, measure and the value of that measure for each magnetic steel width. Within the standard, the applications cover the range of magnetic steel width from 40 to 200, with an increase of 5 mm. It is possible to enter all the core widths available, as low as minus 40 and/or as high as above 200. The option of sorting the table by any column, including multiple selections - by holding down the CTRL key while selecting the various columns - makes it easy to compile and check. If a core width is added, values must be entered for all the dimensions that identify each component of the carpentry involved. To modify existing values, it is necessary to identify the area of the table using the filter at the top left and the order by clicking on the column header. Sorting the table by carpentry + component + core width would make it extra clear.

Table fields (Carpentry details)

Carpentry details: type of carpentry, chosen from the types listed in the drop-down menu of the data input screen under the "carpentry" label.

Air gap composition

Introduction

Generally, the air gap defined in the calculation phase seldom corresponds to the air gap that can be realistically achieved with the insulating materials available. This table defines the possible air gaps based on the standard materials available. Once an optimal air gap has been defined, the applications read this table, choose the closest air gap, and use it, making all the relevant corrections (head air gap, internal air gaps, etc.) so as to obtain an accurate total air gap. This system prevents the air gap data in the documentation for the factory from having to be corrected manually. In addition, the materials in question will be available in the necessary quantities in the bill of materials.
Limits: the envisaged compositions allow the combination of up to two different insulating materials, each with up to three sheets or plate in parallel. Depending on your availability, you can modify this table by inserting other materials and deleting or inserting other lines.

Interlayer insulation thick

Introduction

This table is used only in Clever Small-T and Clever Small-I applications to choose automatically the thickness of the insulation between layers and between windings. The thicknesses automatically chosen by the applications, within a design, can be changed manually.

Table fields (Interlayer insulation)

Temperature class: Element temperature class (A-E-B-F-H).
Conductor material: Conductor material code.
0 = Aluminum
1 = Copper
Conductor type: Enter the conductor type according to the following code:
1 = Flat wire
2 = Foil
3 = Wire
4 = Multi-wire
Nr. of // radial conductors: Number of conductors in radial parallel. With the same thickness, the thickness of the insulation generally has to be increased if there are more conductors in // radial.
Conductor thickness: The thickness of the single conductor.
Insulation thickness: Suitable insulation thickness. No distinctions are made among the various insulating materials because the problem is mainly mechanical.
Index: Value needed by the software. If you need to add a line, proceed as follows:
- Sort the table by index to find out the latest number
- Enter the next number as per the index.

Material costs

Introduction:

This table is used by the applications to determine the description and the unit cost of the materials that will compose the bill of materials. A list of generic materials is available by default, You have also the possibility of importing all the information relating to all your specific items available in your management system.
In fact, when they cannot find the specific material, the applications use the list of generic materials to determine the unit cost and the description of the component they are designing. Please note that the generic materials in the table are given an article number starting with the letter Z and are blue. The list of generic materials includes all groups of materials that are used by the applications. Obviously, from a dimensional point of view, they contain unit costs associated with size ranges with rather coarse limits; otherwise, the list would be too long and difficult to keep up to date. On the other hand, it is important to allow applications to calculate the material cost of an item accurately, including when you are designing special items that need materials unavailable in the company's stock. Hence:

the first task is to enter the unit cost for each line, in accordance with the unit of measurement indicated.
The second task will be to import the liste of the material available in your warehouse and listed in your management system

In general, the cost of conductors can be divided into basic cost and transformation cost. You will find in the table these two items:

Basic conductor AL
Basic conductor CU For each type of conductor there is another item: the transformation cost:
Example: Conductor wire AL <= 2.5 or Conductor foil CU
If you enter a basic cost, applications will take this as the basic conductor cost and add it to the transformation cost when calculating the material cost. If you want your conductor cost to consist of a basic cost and a transformation cost, enter the base and transformation costs as described. On the other hand, if you wish to manage a single cost, enter 0 in the basic cost and enter the entire cost in the transformation field. NB: If entered, the basic cost is added also to the cost of conductors with specific items.

Table fields (material costs):

Description: this is the description assigned to that material (read-only field)
Unit of measure: this is the reference unit of measure for the unit cost value. (Read-only field)
Unit cost: here enter the unit cost in accordance with the unit of measurement
Article: assigned article (read-only field)

Any additions of generic materials are a consequence of application customisation and cannot be added by the user.

Entry of specific materials:

In addition to entering generic costs, as mentioned above, you can import the entire list of materials that are available in your management system. Here is how to proceed:

Export the material data on the management system side:

Extract from the management application a table with the following characteristics:

Column 1 = ARTICLE
Column 2 = DESCRIPTION
Column 3 = UNIT OF MEASURE
Column 4 = Cost

and save it as a file with the extension .csv (readable with Excel). Check, by opening the file with an editor (Notepad for example) that the separator character between the columns is ";". If not, define this rule at the export level. You can ask your IT department, in charge of the management system, to create this file and save it in a folder accessible to you.
Note: It is possible to extract the entire list of materials (not only those used in the design) as the applications will only use the items listed in the technical material tables. In the initial set-up stage, you must decide which price column to use to export (average price or last price or etc.). This is a decision that has a major impact on the result of the cost calculation.

Importing material data into Clever applications:

Once you have obtained the .csv file:

Press the 'Import' button at the top right of this table.
Choose the file from the dialogue box that appears as a file exported from the management system.
Again from the opened dialogue box, click on Open (bottom right)
This will automatically import the file.

Managing the periodic update of the cost of generic materials:

For the periodic update of the cost of generic materials, it is possible to proceed in two ways:

The technical department takes charge of updating the cost directly in this table, as was done the first time. In this case, only the specific items are imported from the management system.
Generic materials are also loaded into the management system, which must be managed as virtual articles (without physical location and with quantity = 0). In this case, the management department will be responsible for updating the costs of generic materials. The materials import file will also include the generics and you only have to regularly import the file from the management system.

Whatever the choice, it is desirable to create a management-side procedure, which automatically exports to a defined folder readable by the technical department regularly (i.e. every week or even every day). In this way, there are the right prerequisites to be able to import up-to-date costs at any time.

Table reading facilities:

As in any other table, you can use the filter in the top left-hand corner to search for a material family or a specific material or change the sorting of the columns.
If the material cost is = 0, it is marked in red.
If you see an article coloured red in the specific tables you have previously filled in, it means that there is no corresponding article in “Material costs” table.
