Abstract

The cogging torque of the aquatic ac synchronous motor is sensitive to the magnetization profiles, the relative angular offset, the magnetic field strength of the rotor magnet, and the structure of the stator core. With the same magnetic profile of the rotor magnet, the cogging torque of the motor is proportional to the trough width of the stator core. For different magnetic profiles of the rotor magnet combined with the same stator core, the cogging torque of the motor varied markedly with the magnetic profiles of the rotor magnet. The computed values of the cogging torque of the motor are in excellent agreement with the experimental values.
