Abstract: Introduction was made to the pole-slot matching principle of brushless direct current motor (BLDC) fractional slot winding. This paper analyzed the effects on winding connection mode, winding coefficient, air-gap magnetic field, pole-arc coefficient, cogging torque, stator magnetomotive force harmonic and the stator iron loss of BLDC. Ansoft and Matlab were used to carry out simulation for four kinds of pole-slot matching BLDC including 12-slot with 8-pole, 12-slot with 10-pole, 12-slot with 14-pole, 12-slot with 16-pole. The result of theoretical analysis was verified, which provides theoretical basis for BLDC design.
Key words: pole-slot match; brushless direct current motor; cogging torque; magnetomotive force harmonics
