PMSM with Thermal Model
This example shows a nonlinear model of a PMSM with thermal dependency. The PMSM behavior is defined by tabulated nonlinear flux linkage data. Motor losses are turned into heat in the stator winding and rotor thermal ports.

The plot below shows motor speed and winding currents as the control system attempts to track a reference signal. A load torque is applied to the shaft, and the effect on the system is shown in the winding currents.
The plot below shows motor speed, torque, and temperature of motor components. The thermal model of the motor models heat transfer between the three windings and the rotor.
