Analytical prediction of electromagnetic performance of surface-mounted PM machines based on subdomain model accounting for tooth-tips

The developed subdomain model accounting for tooth-tips can accurately predict the open-circuit, armature reaction and on-load field distributions in surface-mounted permanent magnet machines. Based on this field model, the electromagnetic performance, such as the cogging torque, back-EMF and electromagnetic torque and winding inductances are calculated. The model can also be used for the evaluation of demagnetisation withstand capability. The finite-element analysis confirms excellent accuracy of the developed analytical model.
