摘　　要：双绕组永磁容错电机在矢量控制(电流滞环)正常工作时,其电机的转矩脉动在额定允许范围内。当电机处于断路故障下,电机若无容错控制时,电机将会产生较大的转矩脉动。对双绕组电机本身设计时,转矩脉动的抑制方法进行论述,并对电机正常工作,无容错控制断路故障时与断路容错控制时,转矩脉动的抑制进行理论分析。同时把DSP28335作为控制器,搭建硬件平台,以双绕组三相永磁容错电机为实验对象,实际验证电机所产生的转矩脉动是否在电机允许的范围内。Vector control （current hysteresis） is used by dual-winding fault-tolerant permanent magnet motor, themotor torque ripple within rated allowable range. The motor has a greater torque ripple without fault-tolerant control in open-circuit. In this paper, torque ripple suppression method of designing dual-winding motor was discussed. In motor normaloperation, no fault-tolerant and open-circuit fault-tolerant control, torque ripple suppression was theoretically analyzed.Using DSP as controller, the hardware platform was built. Taking dual winding three-phase fault-tolerant permanent magnet motor as subjects, it＇s verified that torque ripple is within the allowable range.
