Description
Technical field the present invention is a kind of high efficiency DC brushless motor-AC generator of direct current on-mechanical reversing motor, particularly a kind of used for electric vehicle.(mainly be a kind of high efficiency DC brushless motor, drive other mechanical works done; But when it drives other mechanical works done,, send a part of alternating current, so be called high efficiency DC brushless motor-generator at consumed power not, not under the situation with any load.)
The operation principle of background technology conventional DC motor is that electric energy is converted into electromagnetic energy, then be converted into mechanical energy and drive other mechanical works done, in this process, most electric energy are used to set up electromagnetic field as reactive power consumption, thereby its work doing efficiency is low; Then adopt electromagnet as the excitation stator mostly for the bigger motor of power; The input of electric energy simultaneously is to adopt a pair of carbon brush to cooperate with commutator mostly, so its voltage that need import is higher, consumes more electric energy.Number of patent application is that 97212240 disclosed its working methods of high-power DC motor are the high pressure low current, because required voltage is higher, is applied to electric motor car, automobile, motorcycle and factories and miness electrical equipment, and then required storage battery is bulky.At present no matter from the market, still on the domestic and international disclosed data, and also do not find DC motor on the patent documentation when driving other mechanical works done, do not increasing any device, not under the situation of consumed power, sending a part.
Summary of the invention purpose of the present invention will provide a kind of high efficiency DC brushless motor-generator exactly, at first it is a kind of high efficiency DC brushless motor, it is not increasing any device, can not send a part of alternating current under the situation of consumed power when driving other mechanical works done.We have carried out the research in 5 years, succeed in developing the efficient rare-earth permanent magnet DC brushless motor-generator that can regulate p-m rotor and stator air gap.
The technical solution adopted for the present invention to solve the technical problems is: put an axle sleeve in the rotating shaft of motor p-m rotor, four block sizes watt shape magnet identical, that make with the high-performance rare-earth Nd-Fe-Bo permanent magnet material is equipped with in axle sleeve outside, the different tight arrangement of adjacent permanent magnet polarity, be combined into cylindrical, design a certain thickness air gap regulating sleeve (non-magnet material is made) again, will be combined into columniform watt of shape magnet and closely be inserted in the air gap regulating sleeve.Stator still utilizes the stator cage of prior art, but the stator excitation winding is changed a social system, and is six phase windings with the transformation of the way of original three phase windings, and coil cross-slot not in the coiling process adopts the method for winding of alternating current generator; Make A-A ' and connect, B-B ' and connect, C-C ' and connecing, and in the center of every phase winding, i.e. the position tap of direct current " 0 ", then successively and connect with per three phase winding centre caps.
The invention has the beneficial effects as follows: just add the air gap regulating sleeve that a non-magnet material is made in the rotor outside made from the high-performance rare-earth Nd-Fe-Bo permanent magnet material, just having overcome prior art rotor and stator air gap is difficult to preferably, the size of magnetic force is difficult to adjust and causes motor starting and rotor is motionless, the motor cisco unity malfunction, the defective of band heavy service; Because rotor be can't help armature winding and is constituted, and adopt high performance strong magnetic field intensity rare-earth Nd-Fe-B permanent magnetic material to make, the rotor no current passes through, thereby saved the excitation electric energy, and motor is in work done, under the situation of consumed power not, can also send a part of alternating current, can become direct current by rectification and feed back to input power supply (storage battery), replenish a part of energy automatically, import same electric energy like this, motor is done the merit more than a times more, (uses this motor as electric automobile, can reduce cost, alleviate the automobile own wt, and fill once electricity with the battery of same capacity and can increase distance travelled more than one times) have advantages such as energy-efficient; Also can utilize original stator cage, end cap, rotating shaft, only need to change a p-m rotor, the stator excitation winding is changed system into six phases, coil cross-slot not in the coiling process, adopt the method for winding of alternating current generator, the electric controller of utilization prior art gets final product simple in structure, low cost of manufacture; Henry chloranthus herb shape magnet is equipped with in rotor axle sleeve of the present invention outside, the stator excitation winding is six phases by the three-phase transformation of the way, adopt the design of polyphase multipolar, overcome the defective of motor high voltage low current, owing to be decomposed into six phases, four utmost points, reduced voltage, increased electric current, have good hard mechanical property, and noise low, do not generate heat, operate steadily.
