摘要： A broad-pole type square-wave three-phase brushless permanent magnet direct current motor and an assembling method thereof are disclosed. The number of magnetic poles on a rotor core is: 2P=4. The number of slots in a stator core is: Z=6. Six teeth on the stator are composed of three large teeth and three small teeth. The sum of mechanical angles of one large tooth and one small tooth is 120 degree. Electrical angles corresponding to the mechanical angles are: P*120=240°. Three-phase concentrated windings are wound on three large teeth separately, and only one winding is arranged at each phase. The advantages of the motor are low positioning torque, simple structure, effective production cost, convenient to wind the windings, and low copper loss, etc.
