[Abstract]
The permanent magnet motor for bus was introduced, V type and V type of two kinds of different rotor structure motor torque, straight axis inductance and the flux weakening capability and iron loss properties were analyzed by the finite element method, the simulation of efficiency map of different rotor structures. By comparing and analyzing the characteristics of different rotor structure, the rotor magnetic circuit structure suitable for electric bus driving was selected.
