Optimum design and performance analysis of permanent magnet synchronous motor for vehicle

As the core of electric vehicle, driving motor should have advantages high-power density, wide speed range and small volume. Aiming at demand vehicle drive structural characteristics permanent magnet synchronous motor, by using Motor Cad, a internal rotor (PMSM) was designed analysed in detail this paper. In order to improve anti-demagnetization ability power density structure as built-in compound type. At same time, 8 poles pear shape stator slot were adopted reduce loss efficiency motor. The simulation model established software, its various performances analysed. results showed that design parameters prototype fully meet requirements
