Cogging torque suppression in flux-reversal permanent magnet machines
IET Electric Power Applications(2018)
摘要
In this paper, an analytical expression of cogging torque considering flux-leakage effect for FRPM machines with different magnetization methods of magnets is derived based on co-energy and magneto motive force-permeance model. Then, the influences of machine parameters (including PM width and rotor tooth width) on cogging torque as well as its harmonic spectra are analysed according to this deriv...
