| Abstract: | The overall design process and key issues of high-speed permanent magnet motors were described.The effect of the different air gap length and stator slot number on the motor performance was analyzed.The results show that larger air gap length decreases the rotor torque ripple and rotor loss,and larger number of stator slot decreases the rotor loss. |

| Keywords: | brushless permanent magnet motor high-speed motor design air-gap length number of stator slots |
