Background technology
In machine field, magneto has absolute advantage aspect efficient, power density, the torque density, more suitable to the occasion of volume and power requirement harshness.But its permanent magnet places on the rotor, high-power/and there are the following problems during wide rotating speed operation: and 1, centrifugal force is bigger during high speed rotating, must protect permanent magnet; 2, permanent magnet heat radiation difficulty; 3, magnetic field of permanent magnet and armature field are cascaded structure, and it is bigger that permanent magnet is influenced by armature field, when serious irreversible demagnetization can take place.
The switched reluctance machines stator and rotor are biconvex electrode structures, and no permanent magnet does not have winding yet on the rotor, and its rotor structure is the simplest.High voltage direct current switched reluctance machines starting/generating system also is the focus that Chinese scholars is paid close attention to and studied always, U.S. GE and Sund strand company beginning in 1985 joint research and development 270V high voltage direct current switched reluctance machines starting/generating system (30kw) under the subsidy of USAF, this system now is applied among the up-to-date Joint Strike Fighter F35 of U.S.'s exploitation, and it is to think the 270V high voltage direct current starting/generating system that performance is best at present in the world.
Switched reluctance machines is owing to be half period work, and power of motor density will be lower than magneto.Doubly salient permanent magnet motor, electric excitation biconvex electrode electric machine can be realized the complete period operation of motor by adding the second cover magnetic field, have improved the power density of motor.But the magnetic linkage waveform of double salient-pole electric machine is a unipolarity, and the utilance of motor material is not high, and in addition, the counter potential waveform of double salient-pole electric machine is rule inadequately, if adopt not control rectifying circuit of diode, power factor is lower when being operated in generating state.
The permanent-magnetic-switch flux linkage motor that belongs to the stator permanent-magnet motor with doubly salient permanent magnet motor can be regarded common switched reluctance machines as and slot on stator tooth on structure, inserts permanent magnet.Its rotor structure is identical with switched reluctance machines; From counter potential waveform, double polarity sine waveform back-emf is identical with the BLAC motor, so its power density is greater than switched reluctance machines; From the magnetic linkage waveform, permanent-magnetic-switch flux linkage motor magnetic linkage waveform is a bipolarity, and the utilance of motor material will be higher than doubly salient permanent magnet motor, electric excitation biconvex electrode electric machine.
In sum, the characteristics of permanent-magnetic-switch flux linkage motor are as follows: 1, permanent magnet places on the stator, is easy to cooling, is not subjected to centrifugal force; 2, distinctive " poly-magnetic " effect makes motor also can obtain higher air gap flux density when adopting the lower permanent magnet of coercive force; 3, rotor structure is simple, is easy to high-speed cruising; 4, magnetic field of permanent magnet and armature field are parallel-connection structure, and it is little that permanent magnet is influenced by armature field, and weak magnetic energy power is better than the rotor permanent-magnetic electric machine; 5, motor adopts centralized winding, and is simple in structure, and the end copper loss is little, the electric efficiency height; 6, torque density and power density are better than doubly salient permanent magnet motor and rotor permanent-magnetic electric machine.
But on essence, permanent-magnetic-switch flux linkage motor belongs to the permanent magnet excitation motor, and air-gap field is difficult to regulate, and is difficult to realize the wide speed range operation of motor.
