Background technology
Motor is the main driver part in the modern industry system, and the motor of excellent performance is most important to whole drive system.In recent years, development along with power electronic technology, permanent magnetic material and Control Technique of Microcomputer, permanent-magnet brushless DC electric machine is developed rapidly, permanent-magnet brushless DC electric machine has efficiently, the characteristics of high power density, along with the appearance of high performance permanent magnetic materials, improved the power density and the performance of permanent-magnet brushless DC electric machine greatly.On the other hand, switched reluctance machines is because characteristics such as simple in structure, good reliability obtain application more and more widely.In the middle of the stator tooth of switched reluctance machines, place the permanent-magnetic-switch flux linkage motor that permanent magnet obtains, combine the characteristics of switched reluctance machines and magneto, characteristics such as existing switched reluctance machines property simple and reliable for structure is good have characteristics such as magneto power density height simultaneously concurrently.In permanent-magnetic-switch flux linkage motor, rotor only is made of core lamination, and is simple and reliable for structure; Permanent magnet and armature winding all place on the stator, are highly susceptible to the heat radiation cooling.But the air-gap field of traditional permanent-magnetic-switch flux linkage motor is mainly produced by permanent magnet excitation, is difficult to regulate, and has so just limited the operational speed range of motor.
Summary of the invention
The objective of the invention is to propose the adjustable mixed excitation type switch magnetic linkage motor of a kind of air gap.
Mixed excitation type switch magnetic linkage motor of the present invention, comprise rotor, stator, threephase armature winding, single-phase excitation winding and casing, casing is a permeability magnetic material, and rotor is made of the Alveolus type core lamination, and the stator that is fixed in the casing comprises " U " the shape core unit and first permanent magnet that is arranged in order, " U " shape core unit two bottom sides has groove, first permanent magnet places between two limits of adjacent ' U ' shape core unit, and first permanent magnet is along the circumference cutting orientation magnetizing, and the N utmost point, the S utmost point are alternately arranged; Adjacent ' U ' shape core unit is equipped with second permanent magnet between the base, and second permanent magnet is along the circumference cutting orientation magnetizing, and the N utmost point, the S utmost point are alternately arranged; First permanent magnet on the same radius is identical with the second permanent magnet magnetizing direction, armature tooth is made of first permanent magnet and " U " shape that is close to first permanent magnet both sides limit unshakable in one's determination, the threephase armature winding is for concentrating winding, on armature tooth, single-phase excitation winding is for concentrating winding, in the groove of each " U " shape core unit bottom.
Above-mentioned rotor and " U " shape core unit can be formed by silicon steel plate packing.The opening of said " U " core unit is standard-sized sheet mouth or half opening.Said casing is rolled into by steel plate or is formed by silicon steel plate packing.
First permanent magnet among the present invention and second permanent magnet are neodymium iron boron, SmCo or the ferrite of parallel magnetization.
The present invention can settle magnetic conduction sheet between second permanent magnet and casing, the two ends of magnetic conduction sheet prop up the base of adjacent two " U " shape iron cores respectively.Like this, magnetic conduction sheet constitutes corresponding parallel circuits, under same exciting current condition, can obtain better to regulate the effect of air-gap field.
During work, the threephase armature winding of mixed excitation type switch magnetic linkage motor is linked to each other with the control circuit that connects DC power supply.Utilize rotor-position sensor detection rotor position, determine the conducting state of threephase armature winding thus, because it is the three-phase voltage of f that DC power supply is given threephase armature winding loading frequency by control circuit, then in the threephase armature winding, flow through the three-phase current that frequency is all f, so rotor speed n=60f/p (p is the armature winding number of pole-pairs).Be added to voltage swing and frequency on the threephase armature winding, the then speed of scalable motor by control.Be added to voltage swing and frequency on the threephase armature winding, the then speed of scalable motor by control.Single-phase excitation winding is connect DC power supply, as required excitation winding is imposed electric current forward or backwards, the permanent magnetism air-gap field is played the effect of strengthening or weakening.By adjusting to exciting current direction and size, realize adjusting, thereby regulate the motor speed of service, torque etc. the synthetic air-gap field of motor, be fit to the needs of different occasions.
Beneficial effect of the present invention:
1. permanent magnet excitation and excitation winding electricity excitation is synthesized air-gap field jointly, has realized the controllability of air-gap field, makes mixing excitation type permanent magnet switch magnetic linkage electric machine have better controllability.
2 rotors only are made of core lamination, and are simple in structure, reliable.
3. permanent magnet and winding all place on the stator, are easy to heat radiation, cooling, improve power density.
4. can adopt conventional permanent magnet brushless control of DC method, control flexible, various.
