Electromagnetic–thermal coupled modeling and intelligent thermal management of high-power-density PM machines

Research chain (closed loop):

Harmonic loss → LPTN → Temperature sensing → Thermal management

Four Research Directions

  1. Current-spectrum analysis Analytical spectrum modeling of motor current/voltage under PWM supply, providing inputs for harmonic loss computation.

  2. Harmonic loss analysis Analytical calculation of iron loss and copper loss caused by PWM harmonics.

  3. LPTN mismatch robustness Lumped-parameter thermal network (LPTN) modeling and its robustness against parameter mismatch.

  4. Global temperature sensing Global temperature sensing of the machine and closed-loop intelligent thermal management.
