2. Building the winding architecture - Easy mode – Main principles



Building the winding architecture - Easy mode
1 Selection of the Easy mode for building the winding architecture.
2

Selection of coil pitch. The proposed solutions depend on the number of slots, the number of poles and the number of phases.

Example 1: With 12 slots,10 poles and 3 phases, only one solution is proposed: a tooth winding.

Example 2: With 48 slots, 8 poles and 3 phases, two solutions are proposed: 5 or 6.

For various possibilities, a list of solutions is proposed.

3

Selection of the number of layers. The proposed solutions depend on the number of slots, the number of poles and the number of phases.

Example: With 12 slots, 10 poles and 3 phases, only one solution is proposed: 1 layer.

The three possible cases are illustrated below.

4 Number of parallel paths.

The possible numbers of parallel paths are automatically computed and proposed to the user.

When the user chooses a number of parallel paths, the connections on the winding scheme are automatically updated.

See examples in Auto mode chapter.

5 Selection of winding type: Concentric or Lap.Illustration of these two types of winding is given below.
6 Definition of the phase sequence i.e. the rotation direction of the Magneto-Motive Force (M.M.F):

Clockwise or Counter clockwise.The rotation direction is defined when facing the machine on the connection side.

7 Icon to restore default input values.

Default values are those which defined the winding architecture by using the automatic mode.

8 Icon to apply inputs. Pressing the enter key twice applies inputs too.
9 Icon to export winding data into a text file

3. Number of layers



Building the winding architecture – The number of layers is represented in the winding scheme
1 Example where the No. layers is equal to 1.
2 Example where the No. layers is equal to 2.

4. Coil pitch



Building the winding architecture – Definition of the coil pitch(N° Slot return coil) - (N° Slot Go coil)
1 Example where the coil pitch is equal to 5 - From slot 1 to slot 6 (6-1 = 5).
2 Example where the coil pitch is equal to 6 - From slot 1 to slot 7 (7-1 = 6).

5. Winding type



Building the winding architecture – Definition of the winding type: Lap or Concentric
1 Example for the concentric winding type.
2 Example for the Lap winding type.
