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.
