Description
Technical field
The present invention relates to the switched reluctance motor technical field, especially is a kind of torque enhancement mode switched reluctance motor of brand new.
Background technology
Present switched reluctance motor adopts the biconvex electrode structure; Rotor is only formed by silicon steel plate stacking, has not both had winding also without permanent magnet, and each is wound with excitation winding on extremely stator; Through feeding exciting current successively, stator salient poles and rotor with salient pole are interacted produce torque to the stator excitation winding.Present switched reluctance motor, its stator salient poles and rotor with salient pole magnetic circuit are along the radial arrangement of motor rotation axis.The switched reluctance motor operation principle is followed " magnetic resistance minimum principle ", after the energising, and the trend that the oriented magnetic resistance minimal path of magnetic circuit changes.When rotor with salient pole and stator salient poles dislocation, air gap is big, magnetic resistance is also big; In case stator excitation winding energising will form the magnetic pull to rotor with salient pole, make that air gap diminishes, the magnetic circuit magnetic resistance also diminishes.Meanwhile, can form continuous rotating moment with the energising phase sequence of electronic switch by certain logical relation switching stator excitation winding.Owing to both do not had excitation winding on this configuration switches reluctance motor rotor, there is not permanent magnet yet, thereby simple in structure, reliable.But just because of stator salient poles and rotor with salient pole all along the motor rotation axis radial arrangement; Make that stator and the rotor formed magnetic loop that interacts is longer; Magnetic loss is bigger, and in addition, the salient pole quantity of stator and rotor receives restrictions such as motor volume and external diameter; Be difficult to further improve the control precision of motor operation, still be difficult to break away from torque ripple and the noise in the switched reluctance motor running simultaneously.
Summary of the invention
The object of the invention provides the novel torque enhancement mode switched reluctance motor that a kind of stator salient poles and rotor with salient pole axially are provided with along rotation axis.
For realizing above-mentioned purpose; The present invention provides a kind of torque enhancement mode switched reluctance motor technical scheme; The formation of this switched reluctance motor includes rotor, stator, excitation control power supply;
