SM_3Phase

Inputs

This section is dedicated to the specification of 3-Phase synchronous machines. This applies to synchronous machines with permanent magnets (SM-PM), wound field synchronous machines (SM-WF), and variable reluctance synchronous machines (SM-RSM).

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 for a 3-Phase Synchronous 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	Select the winding technology: either classical winding or hairpin winding technology. This is applied in the winding area.
4	Choose a way to define the diameters of the machine and the airgap. See the dedicated section above.
5	Modify the values of structural data – When relevant the corresponding arrow is displayed on the view. See the list of input data below.
6	Button to apply inputs.
7	Icon to export data into a *.txt or *.xlsx file - please see above illustration.

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”.

Note: For machines with outer rotors, the order of user inputs changes as shown below. The outer rotor machines are considered with a 3-Phase winding. The choice of the number of phases is not possible.
