Design and Analysis of Axially Segmented Double Claw Pole Permanent Magnet Motor
摘要
Abstract
When the permanent magnet synchronous motor is under high frequency conditions,the core loss of the stator and rotor and the eddy current loss of the permanent magnet will increase,which will increase the temperature of the motor,resulting in insulation aging and permanent magnet demagnetization.In order to solve the problem of increasing loss at high frequency,a double claw pole motor with axially segmented claw pole stator and single-stage claw pole rotor with soft magnetic composite materials for stator and rotor core materials is designed.Similar to the problem of excessive torque ripple in the double-salient structure,a combination of rotor magnetic pole offset and stator oblique pole to reduce torque ripple is used.Finally,the electromagnetic design and temperature distribution of the motor are analyzed to verify the rationality of the design.For the selection of claw pole parameters,the effects of the main size ratio,polar arc coefficient,rotor magnetic pole offset distance and stator oblique pole angle on the air gap magnetic density,no-load back electromotive force,torque and torque ripple of the double claw pole motor are studied.关键词
