Description
The present invention relates to rectifying device and production method in a kind of variable voltage speed control asynchronous motor machine.
Existing tandem control alternating current motor, stator winding is arranged, phase-wound rotor, axle, bearing, collector ring, brush, front and rear cover, motor field frame, formations such as the equipped outward three-phase zero formula active inversion cascade adjustable-speed system device of machine, the equipped outward three-phase zero formula active inversion cascade adjustable-speed system device of machine is to be direct current with the rectification of rotor slip electromotive force elder generation, adding a direct current back-emf again goes to subtract each other with it, thereby the corresponding minimizing electric electromechanics of electric current power is apart from reduction on the rotor, motor just slows down apart from decline because of electric power, and whole device utilizes controllable silicon three-phase active inverter circuit to realize speed governing.Structure is complicated, is unfavorable for maintenance, and cost is higher.Existing above-mentioned motor also is provided with collector ring, brush, and these parts contact frictions are easy to generate spark, cause and use the place to be restricted
Task of the present invention is to design the production method of rectifying device and device in variable voltage speed control asynchronous motor machine.
The present invention finishes the work like this: transforming on the basis of existing squirrel-cage threephase asynchronous, mainly is the rotor winding coil of design rectifiable.The rotor coil number is identical with the rotor number, coil is connected on lead-in wire on the tie-point of skeleton cylindrical after being embedded in the rotor successively, the number of poles that coil span produces equates with the stator field number of poles, the rectifier cell of connecting in each coil is evenly distributed successively by same rectification direction, rectifier cell evenly is installed in the insulation framework in advance and fixes, rectifier cell connects with interface on the skeleton end to end, connecting with interface end to end of coil makes it to have of one's own short circuit, fixing with the epoxy resin casting at last, every coil is separate, through colligation, insulation, dipping lacquer, stoving process is handled the back and is formed global facility with rotor.Or rectifier cell is weaved into the one colligation with rotor coil welding back and coil respectively fix through paint-dipping drying formation global facility.Such global facility is exactly the rectifying device in the machine.
Accompanying drawing 1 is a rotor winding loop construction sketch of the present invention.
Accompanying drawing 2 is the present invention's structure diagrams in motor.
Accompanying drawing 3, accompanying drawing 4 are that rotor structure of the present invention and double-deck stagger-wound coil are arranged sketch.
Accompanying drawing 5 is large and medium motor rectifier cell technology arrangement sketches.
Now be described with reference to the accompanying drawings the present invention, the present invention can be at the squirrel-cage three-phase asynchronous electric Machine is transformed on the basis, mainly is the rotor coil of design rectifiable. By reference to the accompanying drawings 2 explanation the present invention, brushless transform speed regulating asynchronous motor is by stator winding (6), rotor core (2), rotor coil (3) and be connected on the interior fairing of machine that the rectifier cell (4) in the rotor coil (3) consists of, motor shaft (1), bearing (8), motor casing (9), fan (12) consist of. The production method of fairing is as follows in the machine: be separate during rotor coil (3) coiling, in rotor core (2) groove, divide two layers to be embedded in successively in motor rotor core (2) groove by the lap wound method, see accompanying drawing 3, accompanying drawing 4, the rotor slot number is identical with the rotor line number of turns, the number of poles that coil pitch produces is equal to the stator field number of poles, by same rectification square between the head and tail that rectifier cell (4) is connected on successively every rotor coil (3) and firm welding, through insulation processing, miniature motor with flush type respectively with rectifier cell (4) colligation in rotor coil (3) end, see accompanying drawing 3. Large and medium motor evenly is installed in rectifier cell elder generation five equilibrium on the insulation framework (13), see accompanying drawing 5, rectifier cell connects with wiring point (14) on the skeleton end to end, interface (14) connects end to end with rotor coil (3) respectively, with epoxy resin rectifier cell is solidified in being fitted on the insulation framework on the motor reel at last again, process rear and rotor formation global facility through colligation, insulation, dipping lacquer, stoving process. Other each production technology is equal to existing electric motor production technology. Rotor global facility is installed on the motor reel with back-up ring (11) and block (10). Fairing is like this work: because two effective edges of every rotor coil are under the magnetic pole of the stator simultaneously most effectively, and every coil is separate to have short circuit of one's own after rectification, by same rectification square to being evenly distributed on successively on the rotor circumference, after stator winding passes through three-phase alternating current, namely produce with the fundamental wave magnetic field with the leg speed rotation in the air gap of stator and rotor, this rotating excitation field is two effective edges of each coil of cutting rotor successively; Make rotor coil produce successively semi-wave DC, this DC current simultaneously and stator field interact, produce moment, with the direction along rotating excitation field overcome mechanical loss and load force apart from and rotate. The three-phase alternating voltage that changes stator then can make rotor form infinitely variable speeds.
Most preferred embodiment of the present invention is as follows: transform on small-sized Y series threephase asynchronous, stator coil is same as prior art around embedding technology and mounting process, mainly be to change the rotor manufacturing process, be about to squirrel-cage cast-aluminum rotor manufacturing process and change over rotor winding technology.The rotor coil number is equal to the rotor number, separate between every coil, the number of poles that coil span produces equates with the stator field number of poles, coil embeds in the rotor core groove successively, in every coil by same rectification direction with rectifier cell be series at this coil end to end between weld, and make it to have of one's own short circuit, the rectifier cell of miniature motor adopt flush type technology successively equably colligation at end winding, see accompanying drawing 3, for large and medium motor is that rectifier cell is evenly distributed on predetermined fixed on the insulation framework in advance five equilibrium, see accompanying drawing 5, the head and tail of rectifier cell drawn respectively receive on the outer interface of insulation framework, with epoxy resin rectifier cell and skeleton are solidified into to press-fit after the one and are fixed on the armature spindle.After colligation, dipping lacquer, stoving process is handled and rotor forms global facility, finish brushless variable voltage speed control asynchronous motor rotor manufacturing process, the rotor integral body of such reincarnate is packed in the middle of original stator, other technology is identical with existing technology, finishes brushless variable voltage speed control asynchronous motor production task.
The present invention compared with prior art has the following advantages: the induced-current that the electronic rectifier element produces the rotor coil conductor carries out the rotary integral parts that self-commutation is realized electromechanical integration, changing the stator input voltage can realize rotor stepless speed regulation, speed adjustable range is big, and can steady running there be unusual noise, can not produce electric spark in the present invention's running, rectification in the machine, simple in structure, cost is low, starting current times is little, and the starting torque multiple is big, low speed power factor height, nothing is paid and is added the speed governing energy consumption, and economize on electricity significantly.
