DC_PM

Inputs

This section is dedicated to the specification of DC machines. This applies to DC machines with permanent magnets (DC-PM).

The user inputs, the cross section, the axial view and datasheet can be selected and displayed.

Here is the process to modify the structural data from the general data panel.

Table 1. Process to modify the topology structural data - Example of a DC machine with Permanent Magnets and Inner Rotor


1 Open the Specification panel (Click on the icon Specification).
2 Select the topology section for defining the structural data of the machine, meaning the main overall dimensions (stator and rotor outer and inner diameters) and characteristics like the number of slots, poles.
3 Choose a way to define the diameters of the machine and the airgap. See the dedicated section above.
4 Modify the values of structural data – when relevant, the corresponding arrow is displayed on the view.

See the list of input data below.
Here are the user input parameters to define the structural data of the machine:
  • Stator outer diameter
  • Stator inner diameter
  • Stator length
  • Number of poles
  • Airgap length
  • Rotor outer diameter
  • Rotor inner diameter
  • Rotor length
  • Number of slots

The modification of the structural data can lead to the modification of the user input parameters in defining dimensions of parts like slots or magnets. When modifications occur, a warning is displayed.

The application ranges for structural data are defined in the section “Topology / Structural data – Validity domain”.
