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.

摘要： The present invention relates to a control technology of a three-phase DC motor. In order to resolve a problem in the prior art that the good current closed-loop control has not been realized on a three-phase square-wave brushless DC motor, the present invention provides a brushless DC motor control system, wherein cathodes of freewheel diodes D1, D3 and D5 are independent of input terminals of their respective switch tubes and connected in parallel to a sampling coil L1, and anodes of freewheel diodes D4, D6 and D2 are independent of output terminals of their respective switch tubes and connected in parallel to a sampling coil L2. The present invention can use a single resultant current sensor to completely and continuously sample the three-phase current existing during the motor is on and performs current freewheel, and perform the continuous closed-loop control on the three-phase current with a single current closed-loop regulator, thereby increasing dynamic and static indexes of the motor significantly.

摘要： This invention relates to a three-phase square-wave permanent magnet brushless DC motor for solving problems of the existing square-wave permanent Magnet Motor and sine-wave permanent magnet motor. In this invention, the number 2P of magnetic poles on the said rotor core is 8; the slot number Z of the said stator core is 12, accordingly there are 12 teeth, including three big teeth, three medium teeth and six small teeth; the ratio of their mechanical angles is 50° (±5°) for big teeth: 40° (±5°) for medium teeth: 15° (±5°) for small teeth, and the sum of the mechanical angles of one big tooth, one medium tooth and two small teeth must be 120°. Three-phase concentrated windings are respectively wound on the big teeth and the medium teeth, in which there are only two concentrated windings for each phase, thus there are only 6 concentrated windings for the three-phase motor. With driven by three-phase square-wave current, the said motor can produce a smooth torque which ripple index corresponds to that of the sine-wave permanent magnet servo motor, at the same time, it also has a plurality of advantages including windings end minimization, air-gap minimization, material minimization, cogging torque minimization and loss minimization and so on.
