Abstract

In view of high frequency power and high speed rotation, many problems of high speed motor are more serious than conventional one, such as electromagnetic field, stress field, rotor-dynamics and drive system. Based on a claw pole motor with outer permanent magnetic rotor, the theoretic analysis of outer rotor stress at high speed is deduced, and the verification is achieved by finite element method. Because high speed rotor design should be investigated based on the dynamic properties analysis, the rotor dynamics and comparison results by finite element method are given and analyzed. In addition, a senseless drive system is simulated, and the experiment research of high-speed motor is carried out, the feasibility of the developed drive system has been verified by experimentation.

Key words： High speed motor permanent magnet motor claw pole motor multi-physical field analysis drive system design
