This paper compares the electromagnet torque characteristics of ALA+PM rotor synchronous motor with the conventional permanent magnet motor, the former holds on linearity relationship with the increase of the stator flux linkage, but the later needs restrict condition. The direct electromagnet torque control is the best control method for ALA+PM rotor synchronous motor, but the stator current can increase if the stator flux linkage is bigger or smaller than magnet flux linkage, the maximum torque current percent ampere control method is used to overcome the disadvantage.
