Abstract
This invention relates to a short magnet circuit mixed excitation switch magnetic resistance motor, in which, multiple stator slots are opened on the internal cylinder surface uniformly, the length direction of the slots are parallel to the axial lead and through the surface of the internal cylinder, the thickness of the pole body between every two slots is the same, a magnet is inserted in each slot, the N pole and the S pole of the magnet are connected with the two vertical wall faces of the slots and an excitation winding is winded on the root of each pole body of the stator.
Description
Technical field
The present invention relates to a kind of Hybrid Excitation Switched Reluctance Motor, belongs to machine field.
Background technology
Existing switched reluctance machines, its stator, rotor are salient-pole structure, and by the stator excitation winding is switched on successively, stator poles and rotor pole interact and produce torque.Owing to both do not had winding on the rotor, do not have permanent magnet, so motor be simple in structure, reliable yet.But all do not use permanent magnet just because of stator and rotor,, just need big exciting power, so both limited the motor properties volume ratio, strengthened the cost of drive system again in order to obtain big output torque.Publication number provides a kind of Hybrid Excitation Switched Reluctance Motor for the patent of CN1560987A, though it can solve the problems referred to above, but its stator slot is divided into sipes and narrow groove, there is the gap in the back between sipes interior loop and permanent magnet so roll off the production line, and causes that space availability ratio reduces, torque is unsmooth.
Summary of the invention
The Hybrid Excitation Switched Reluctance Motor space availability ratio reduces in order to solve, the rough problem of torque, the invention provides a kind of short magnetic circuit mixing exciting switch Magnet resistance motor.
Motor of the present invention is made up of stator, rotor, excitation winding and a plurality of permanent magnet; Rotor is the cylinder that permeability magnetic material is made, and evenly has a plurality of deep trouths on the external cylindrical surface of rotor, and the center of rotation line parallel of the length direction of deep trouth and rotor also runs through the outer cylinder surface of rotor; Stator is the cylindrical sleeve that permeability magnetic material is made, and stator is enclosed within the outside of rotor, and makes between the external cylindrical surface of the inner cylinder face of stator and rotor and be provided with air gap, and the axial line of stator and the rotational axis line of rotor coincide simultaneously; Evenly have a plurality of stator slots on the inner cylinder face of stator, the length direction of stator slot and the axis parallel of stator also run through the inner periphery of stator, and the thickness of the pole body between per two stator slots all equates; Be inlaid with a permanent magnet in each stator slot, the N utmost point of permanent magnet and the S utmost point are connected two perpendicular walls of stator slot respectively, all are wound with the excitation winding on the root of each pole body of stator.
Operation principle: when the excitation winding no power, the magnetic line of force of permanent magnet does not pass through air gap, but passes through the pole body and the yoke portion closure of stator; When excitation winding was alived, the magnetic line of force path of the path of its electric excitation magnetic line of force and permanent magnet formed parallel circuits, and two magnetic fields form flux circuit by stator pole body, air gap, rotor.On-off action by electric excitation magnetic potential (excitation winding electric current logical and disconnected) is controlled the path and the size of magnetic flux power of the magnetic line of force of permanent magnet, realizes that the torque of motor is controlled.Because the inner cylinder face of stator of the present invention is evenly to have a plurality of grooves, so brought following advantage: 1, the staff can evenly be rolled off the production line when rule, is easy to the winding dynamics of control coil; 2, very close to each other in the stator slot, improved space availability ratio; 3, a permanent magnet can be installed in each stator slot, improve efficiency of motor, reduce the torque pulsation of motor.The present invention has the applications well prospect at robot, Digit Control Machine Tool and motor vehicle etc.The present invention has very high ratio of performance and volume and performance weight ratio, can use as motor, also can use as generator, and easy care simple in structure.
