| Abstract: | Maxwell 2D finite element analysis of 12-pole surface PMSM was simulated by Ansoft 13,aiming to study the EMF and flux leakage coefficient caused by different PM polar arc coefficient.By processing the simulation results,obtained chart of polar arc coefficient with the THD and fundamental value of EMF,and a curve of polar arc coefficient with flux leakage coefficient likewise.4-pole and 6-pole motors which have conformable polar arc coefficient were presented to verify the conclusions,and then compared the THD of EMF and leakage coefficient with 12-pole motor. |
