摘要
通过分析空心杯电机的电气性能,提出了一种定子电压相位超前转子磁链90°的控制策略,以及通过改变母线电压以减小绕组在一个开关周期内电流波动的方法。通过仿真和试验结果验证了所提出的控制策略的有效性。
Due to the outstanding energy saving, performance smart control performance and smooth running performance, coreless motor has been a development trend of motor as a high efficiency energy conversion equipment. Based on analyzing the special electric character, A novel control strategy of coreless PMSM by orienting the stator voltage a leading angle of to PM rotor flux link, and a method of tuning the DC link voltage to reduce the current ripple in every switching period were introduced. The experimental and simulation results verify the validity of the proposed control strategy.
