摘要：
This paper deals with magnetic field calculations and FE model-based prediction of torques in a PMBLDC motor. As a function of the rotor position, the torque produced by these machines has a pulsating component in addition to the dc component. This pulsating torque, according to the motor drive, has a fundamental frequency corresponding to six pulses per electrical revolution of the motor. The finite element analysis (FEA) has been employed to assess electromagnetic torque and cogging torque waveforms. The torque ripple in dependence of the switching angle for the control device is thoroughly investigated.
