Abstract: This paper analyzed the inadequacies of fluxweakening by way of existing control strategies based on the fluxweakening principle of permanent magnet synchronous motors. From the motor body structure, the paper explained the works of fluxweakening permanent magnet synchronous motor, and adjusted magnetic field through designing special rotor structures or adding to some mediation devices. The paper proposed the research status of five types of fluxweakening permanent magnet synchronous motor and provided ideas for some special fluxweakening application.
