ABSTRACT Line start permanent magnet synchronous motors with high efficiency and high power factor in steady state are meet the requirements of standards for high efficiency motors. They will be a feasible solution for replacing partially squirrel cage induction motors (SCIM) which widely used at the present time. Howerver, their performance are mainly depended on the configuration of their rotor configuration, sizes of permanent magnets, permanent magnet materials, phase back-EMF value (E0),... In designing process, if the EMF value is not suitable for motor, the efficiency of the motor will be down. Even, the efficiency of LSPMSM is lower than SCIM with the same power. Therefore, this paper studies the effect of rotor’s configuration on LSPMSM’s phase back-EMF waveform and determines phase back-EMF value. This study will help the motor designers computing E0 and modifying configuration of LSPMSM to reach appropriateE0 value.
