New Type

The present motors are required to high speed, high efficiency, high power density but low pulsating torque. Traditonal rare-earth permanent magnet motor shows its defect; Halbach Array is a new type of permanent magnet structure: magnet field presents unilateral with the sinusoidal distribution. The structure makes the magnetic density of motor’s air gap larger relatively while the magnetic density of rotor’s yoke smaller. And it can help to reduce the motor’s pulsating torque and its size, as well as to raise the power density of motor. The result of finite element analysis based on ANSYS shows that the above structure is able to decrease the mass of motor, to widen the width of air gap and obviously to improve the multi properties of motors.
