Fundamental Wave SM_Permanent Magnet

Permanent magnet synchronous induction machine

Description

The FundamentalWave SM Permanent Magnet (or SM Permanent Magnet) component models a permanent magnet synchronous induction machine. Resistances and stray inductances of the machine refer to an $m$ phase stator. The symmetry of the stator is assumed.

The model takes the following loss effects into account:

 • heat losses in the temperature dependent stator winding resistances
 • optional, when enabled: heat losses in the temperature dependent damper cage resistances
 • friction losses
 • core losses (only eddy current losses, no hysteresis losses)
 • permanent magnet losses
