Reply To: Y wiring method and the start and end points of winding.

Hello,

In Maxwell Circuit Editor, you can create an external inverter circuit including windings and Y connection, and then connect it to Maxwell 2D/3D.
If you do not use an external circuit, the Y connection excitation setting is explained in the following help. In Maxwell 3D transient designs, the Y connection setting is supported since 2020R2 version.

Bulk coils are often used to simulate electrical machines, and the start and end points of U, V, W windings do not need to be considered. These coils are modeled for each slot, and after specifying the direction of current flow at the coil terminal, each coil is assigned to U, V, W windings.
