The paper presents magnetostatic analysis of electromagnetic torque of surface-mounted permanent magnet motor with external rotor that is devised to be used for direct drive electric hand planer. Maxwell’s stress method and experimental method at stalled rotor are used to determine the electromagnetic torque for the analysis in this paper. The analysis of the obtained electromagnetic torque-angle characteristics shows that the studied motor has significant electromagnetic torque pulsations. The way of torque pulsations minimization by stator slots skewing, using multi-slide virtual model, is also analysed in this paper.
