Coil

Description

Table 1. Definition of the coil – Case of Circular wires


1 Definition of the wire topology, Circular or Rectangular
2 Choice of the method to fill the slot:

Three ways are allowed to fill the slot: Orthocyclic, Random, Layer. See the below illustrations.
3 Choice of method to group the elementary wires.

Three ways allow to fill the slot: Grouped, Horizontal, Vertical.
4 Description of the coil and dimensions of elementary wires + twist options
4.1 Number of turns per coil
4.2 Number of wires in parallel in a conductor (per turn) i.e., number of wires in parallel in each conductor
4.3 Wire dimensions - Diameter (without insulation) (1)
4.4 Minimum distance between insulated wires to be considered for modelling inside the Flux® 2D environment.

When there is no wire insulation, Inter-wire space represents the minimum distance between the bar wires (2).
Note: Different ways are available to choose the wire diameter:
  • Directly entering the value of the wire diameter (without insulation)
  • Choose the diameter from the American Wire Gauge table in which available wire diameters are listed (without insulation)
  • Choose the diameter from the Metric Wire Gauge table in which available wire diameters are listed (without insulation)
Note: Illustration of inter-wire space

This value is considered in the Motor factory for computing the filling factor and while exporting a model into Flux® environment (Export area) for building the corresponding finite element model.
