Abstract：When the permanent magnet assisted synchronous reluctance motor（PMaSynRM）runs at highspeed with flux-weakening control，the DC bus voltage utilization is not high，and the efficiency and torque output capacity of the motor are low. Therefore，a flux-weakening control strategy of permanent magnet assistedsynchr...
