The utility model relates to a double-functional special motor. The magnetic pole pair groups of a plurality of pairs of stators winding with windings are fixedly connected together by a front connecting plate and a back connecting plate, and the magnetic circuit of each pair of the magnetic pole pair groups is independent and is not disturbed mutually. The middle bearing between the front connecting plate and the back connecting plate is provided with a rotary shaft, and the pole block of a rotor is fixed on the rotary shaft by a supporting frame. A rectifying disc is arranged on the connecting plate, and the rectifying disc is provided with a leading wire, a winding leading wire and a control circuit which are connected together. The applied voltage is switched on with an exciting winding by an electric brush and a rectifying piece, and the magnetic field produced by the exciting winding and the magnetic drawing force produced by the magnetic field induced by the pole block of the corresponding rotor make the rotary shaft rotate.

Description
The utility model is to belong to motor with stepless speed regulation and low rotation speed large torque motor technology field.
Adjustable-speed motor commonly used at present has two kinds: a kind of is to carry out speed governing by electromagnetic slip clutches, and another kind of is frequency control.These two kinds of speed regulating methods, the speed control device investment is high, consumes a large amount of electric energy during other speed governing, and these two kinds of speed regulating methods all can not carry out speed governing in the low-speed range simultaneously.Two kinds of functions of difunctional extraordinary motor are: the one, and stepless speed regulation does not need to add speed control device, and the speed governing consumed power is few; Another function is to be used as the low rotation speed large torque motor to use, and has saved reduction of speed increased force will moment devices such as gear, and this is an especially big breakthrough.
The purpose of this utility model not only provides a kind of novel difunctional extraordinary motor, and electric motor structure also made significant improvement, makes the motor material saving, and is in light weight, can make jumbo motor.This difunctional extraordinary motor be the disc type electric device for valve (patent No.: 89211407.X), the extraordinary motor of column type (patent No.: 92218555.7) and the extraordinary motor of stepless speed regulation (No. 1, patent: on the basis 94241682.1), through long-term practice in addition significant improvement develop.
Difunctional extraordinary motor is different with above-mentioned several patent electric motor structures, and stator is made up of many groups pole pair group, and these pole pair group magnetic circuits are independent separately, all are tied with magnetic pole winding, fly-wheel diode in parallel on every group of pole pair group.By two gusset pieces in front and back magnetic pole of the stator is formed a whole to group, in the middle of gusset piece bearing is housed, rotating shaft is assemblied in the brearing bore.Rotor is housed in rotating shaft, and rotor is made up of support and utmost point piece.Fixing middle round-meshed rectifying disc on a gusset piece, the circular hole in the middle of the rectifying disc is passed in rotating shaft.Corresponding commutator segment is linked together on magnetic pole of the stator winding leads and the rectifying disc, applied voltage is added to collecting ring on the rectifying disc by control circuit, and by the brush that rotates with rotating shaft the applied voltage on the collecting ring is guided on the corresponding magnetic pole of the stator winding that joins with commutator segment.When stator winding electrifying magnetic field center line that produces and the magnetic field center line position of responding to by respective rotor utmost point piece are inconsistent, produce the magnetic tensile force, promote the rotor pole piece and rotate, drive rotating shaft and rotate.When utmost point limit behind the magnetic pole of the stator when corresponding rotor pole piece leading pole tip is close, magnetic tensile force maximum, this moment, this group magnetic pole of the stator winding should be switched on; When the magnetic pole of the stator and the rotor field center line of corresponding induction were consistent nearly, the magnetic tensile force was minimum, and this moment, this magnetic pole of the stator winding should cut off the power supply.So, magnetic pole of the stator winding wheel flow-thru electrode forms artificial rotating magnetic field, drives rotor rotation, and rotating speed is decided by institute's bringing onto load and applied voltage size.
The utility model is compared with first three items patent motor, has following several characteristics: one, especially rotor structure is simple especially for electric motor structure, and the extraordinary motor weight of therefore this New-type bifunctional is light, material is economized; Two, magnetic circuit is short, efficient is high; Three, the motor external form can be made into flatly, is fit to some load needs; Four, can make jumbo motor; Five.The electric function of this structure is brought into play difunctional effect well.
