Abstract :
In this paper, a new control algorithm is proposed to improve the efficiency of multiphase permanent magnet synchronous motor with outer-rotor type (MPMSM). The improved efficiency is obtained by using the change of the phase number from 6-phase motor to 3-phase motor and reducing the switching loss by using the bi-direction switch between two H-bridge inverter of six phase to change the number of the phase. The simulation and experimental results are presented to demonstrate the feasibility and advantages of the proposed algorithm.
