This example compares a time transient and a quasi static model of a synchronous reluctance machine. The machines are fed by a current source. The current components are oriented at the magnetic field orientation and transformed to the stator fixed reference frame. This way the machines are operated at constant torque. The machines start to accelerate from standstill.

Simulate for 2 seconds and plot (versus time):
