【Abstract】 According to the relevant specifications of a certain model of blower, a high-speed magnetic levitation motor with a three-stage solid rotor structure was designed. The rotor structure of the motor was determined, and electromagnetic design and magnetic levitation bearing parameter design were carried out. The performance of the electromagnetic scheme was verified by finite element analysis. The rotor using high-temperature alloy sheath was subjected to stress analysis to examine its changes under different rotational speeds and temperature rise conditions, and the strength of the rotor was calibrated. The intrinsic frequency and critical speed of the rotor structure were analyzed by modal simulation, thus proving the rationality of the motor design. The research results provide theoretical references for the design and application of high-speed magnetic levitation motors.更多还原
