Abstract

Based on the combination of high-speed magnetic bearing and high-speed permanent magnet motor, high-speed maglev centrifugal permanent magnet direct drive frequency conversion unit is the future development direction of air conditioning. In order to make permanent magnet motor control more suitable for high-speed magnetic levitation unit performance requirements. The research on sensorless control of high-speed permanent magnet motor in the background of high-speed magnetic levitation centrifuge is carried out in this paper. The sensorless position observation, maximum torque-current ratio control, flux-weakening control, harmonic and shaft extension suppression, and generation mode of permanent magnet motor are studied. Finally, it is verified in the magnetic levitation unit, which can meet the requirements of the unit.
