A four phase outer rotor switch magnetic resistance motor includes rotor and stator, said rotor is set outside of the stator, and there is not brush, winding, permanent magnet on the rotor, twelve poles or six poles formed by twelve grooves or six grooves are set on the inner of the rotor; eight poles formed by eight grooves which are corresponding with rotor are set on the outer of the stator, and they constructs biconvex pole structure with rotor; centralized coil is winded around the pole plate of the stator, the coil which is relative at radial direction composes a phase stator winding, eight coils composes four phase stator winding. The structure switch magnetic resistance motor can realize the direct drive for fan, electric car, electric roller, without middle transfer device, the reliability of drive system is not only improved, but also the energy spoilage is decreased, the structure is simple and firm, the cost of manufacture is low, and it possesses wide practicability.
