Structure optimization of the built-in permanent magnet synchronous motor for fuel cell bipolar plate production equipment
摘要
Abstract
To effectively improve the torque performance of the permanent magnet synchronous motor and reduce the cogging torque,the built-in permanent magnet synchronous motor with 48 slots and 8 poles was selected as an example,and take the key parameters of the rotor as the optimization parameters without changing the radial radius of the rotor,and the multi-objective optimization of the motor was carried out based on the Taguchi algorithm,so as to increase the torque performance of the motor on the basis of effectively reducing the cogging torque.On the basis of the optimization,the three typical operating conditions of permanent magnet synchronous motors,including no-load operation,rated load and maximum speed operation,was simulated by the finite element analysis.The results show that the peak value of cogging torque decreases from 1.8 N·m to 0.9 N·m,the average electromagnetic torque under rated load increases from 73.17 N·m to 77.12 N·m,and the average electromagnetic torque increases from 37.3 N·m to 38.42 N·m at the maximum speed,respectively,achieving the goals of improving the torque performance of permanent magnet synchronous motor and reducing cogging torque.关键词
