Problems solved by technology
Electric excitation double salient pole motor has more excitation coils. When the coils are inserted into the wire, some punching sheets have loose slots, and some punching slots are tight. It cannot guarantee that the slot fullness of each slot is consistent, which is not conducive to Increased slot fill rate

The invention discloses a double-salient pole motor with a novel laminating structure. The double-salient pole motor comprises a stator (1) and a rotor (2), wherein the stator (1) has twelve poles, and the rotor (2) has eight poles; a stator lamination is provided with eight small grooves and four large grooves distributed at intervals of every two small grooves, an armature coil (4) is arranged in the small grooves respectively, an armature coil (4) and a magnet exciting coil (3) are arranged in the large grooves in upper and lower layers respectively, an insulating layer (5) is arranged between the armature coil (4) and the magnet exciting coil (3), and the armature coil (4) in the small groove and the armature coil (4) in the large groove have the same area. By adopting the structure, the double-salient pole motor can ensure consistent space factors of laminating tooth grooves of the motor stator, is favorable for improving the space factor, and prevents the coils from vibrating in the laminating grooves under the action of electromagnetic force so as to ensure the safe operation of the motor.
Description
technical field [0001] The invention relates to a double salient pole motor, in particular to a double salient pole motor with a novel punching structure. Background technique [0002] As we all know, the name of the doubly salient motor mainly means that the structural shape of the stator and rotor punching of this type of motor is doubly salient, and the switched reluctance motor is a typical form of doubly salient motor. In 1998, Nanjing University of Aeronautics and Astronautics designed a double salient pole motor with electric excitation winding as the excitation source on the basis of switched reluctance motor. The switched reluctance motor is converted to an electrically excited switched reluctance motor. The motor maintains the characteristics of good dynamic and static speed regulation, reliability and easy control of the traditional DC motor. It has a wide range of speed regulation. The magnetic pull between them is generated. For a general switched reluctance ...
