Description
Summary:The torque overload capability of permanent magnet synchronous motor(PMSM) is very important in transportation applications, which means instantaneous acceleration ability. In the interior PMSMs, the reluctance torque is generated due to the asymmetry of the magnetic circuit, which contributes to the torque overload capacity. In this paper, finite element models(FEMs) of PMSMs with different rotor structures are established to study the torque overload capability. Frozen permeability method is used to analyze the distribution change of rotor permeability under different operating conditions. The torque overload capabilities of different rotor structure are compared. The interior rotor type suitable for overload condition is obtained.
