In this paper, the skewing slot is applied to the PM surface mounted Brushless DC Motor 20kW 36 slots and 12 magnet poles (Z = 36, p = 12) for eliminating torque ripples. To observe the skewing stator effect, the stator lamination layers are skewed with different angles. With determined skewing angle, the cogging torque eliminated theoretically and flux density space harmonics are also reduced |
