Winding outputs

2. Definition – illustration
Slot composition
1 Wire also called strand.
2 Conductor. That also corresponds to a turn section (one conductor = one turn).

A conductor is composed with one or several wires in parallel.
2* The hatched area corresponds to the conductor’s useful area. Area which includes: the wires + insulation + free space. This is not the conductive area.
3 Coil which is an assembly of several conductors (i.e. several turns per coil).

3. Inputs

Label Symbol Tooltip, note, formula

4. Settings – Coil – Conductor

Label Symbol Tooltip, note, formula
No. turns per coil Turns Number of turns per coil.
No. wires in hand No.Wires Number of wires in parallel in a conductor (per turn) i.e. number of wires in parallel in each conductor.
Wire topology * Wire topology – Circular or Rectangular.
Wire diameter ∅ wire Wire diameter (without insulation).
Wire width * For rectangular shape type wire.
Wire height * For rectangular shape type wire.
Conductor topology * Cable topology – Circular or RectangularCoil conductors are grouped inside a circular shape or a rectangular shape. It is linked to the wire topology.Rectangular wires impose a rectangular cable. Circular wires impose a circular cable.
Conductor diameter * Cable diameter (without cable insulation) i.e. Diameter of the circle which are grouped inside all the coil conductors.
Conductor width * Cable width (without conductor insulation) i.e. Width of the rectangle which are grouped inside all the coil conductors - Case of rectangular shape type wire.
Conductor height * Cable height (without conductor insulation) i.e. Height of the rectangle which are grouped inside all the coil conductors - Case of rectangular shape type wire.

5. Setting – Coil Insulation thickness

For more details see section “Choice of winding MATERIALS”. All the thicknesses are defined as user input parameters in winding – Settings – Coil tab.

Label Symbol Tooltip, note, formula
Wire * Insulation thickness of the wire
Conductor * Insulation thickness of the conductor
Coil * Insulation thickness of the coil
Liner * Insulation thickness of the liner
Phase separator * Insulation thickness of the phase separator
Impregnation * Insulation spread inside the slot
Impregnation goodness * Quality of impregnation (percentage of winding impregnation)


6. Settings – Coil – End winding

This part characterizes the end-winding and the resulting conductor dimensions.

For additional information refer to the chapter dedicated to the coil and conductor settings - End-winding topology and dimensions.

Label Symbol Tooltip, note, formula
End-winding topology * End-winding topology: U-shape, C-shape or Y-shape.
C.S. total extension * Connection side total extension.
C.S. straight extension * Connection side straight extension
Axial overall length * Axial overall length. Length between the two extremities of the winding i.e. between connection side and opposite connection side.
O.C.S. total extension * Opposite connection side total extension.
O.C.S. straight extension * Opposite connection side straight extension.
Total conductor length * Total conductor length.
Mean turn length * Mean turn length.
Coil connection length * Additional length corresponding to the connections between coils.

7. Settings – Calibration factors

Label Symbol Tooltip, note, formula
Resistance factor * Setting of the “Resistance factor”. It allows adjusting computation result of resistance with resistance measurement. Thus, the resulting phase resistance value is considered wherever it is.
Inductance factor * Setting of the “Inductance factor”. It allows modifying the computation result of end-winding inductance.

Thus, the resulting end-winding inductance value is considered wherever it is.
Ref. temperature * The reference temperature.

First, resistance values are always computed by considering a temperature equal to 20°C.

However the user can also define his own reference temperature to compute the corresponding phaseresistance and Line-Line resistance

values.

Caution : This reference temperature is used only in the winding design environment.

The test temperatures are defined in the test settings (refer to TEST chapter).
