摘要: A motor structure in a salient pole type DC which torque ripple and cogging are reduced, without deceasing efficiency, the constant irregularity of rotation reduced. The magnetic flux density distribution an air gap approaches sine wave shape by forming groove vicinity neutral part (a boundary N-pole S-pole) rotor magnet.
