Abstract

This paper presents two high speed brushless DC (BLDC) prototype motors: one is related to the surface-mounted permanent magnet (SPM) rotor, the other to the interior permanent magnet (IPM) rotor. The IPM rotor is a combination of magnets magnetized in tangential direction and in radial direction. As for the two prototype motors, the magnetic field distribution in the air gap calculated by 2D finite element analysis (FEA), the back electromotive force (EMF) waveforms obtained by 2D FEA and test, and the test speed-torque curves are compared respectively. The comparison results suggest that the leak flux in the IPM rotor reduces the air gap flux per pole and that the no-load speed and the speed-torque curve slope of the IPM motor are much greater than the no-load speed and the speed-torque curve slope of the SPM motor.
