Abstract
This paper presents an implementation of square wave drive on super-high-speed PMSM. In order to solve the problem that the rotor temperature of super-high-speed PMSM rises sharply, this paper compares SVPWM method with square wave method and designs a pre-BUCK PMSM drive. The new drive uses sensorless control algorithm and gets the position signal from BEMF. The simulation and experiment results are shown to exhibit the performance of the drive. The experiments are conducted at speeds up to 50000rpm and the results show that the drive can restrain the rotor temperature from rising remarkably.
