The stator iron core is provided with a first winding and the second winding; the first winding is arranged on an upper layer of a wire winding groove, and the second winding is arranged on a lower layer of the wire winding groove. The beneficial effects of the invention are that: the far pole ratio three-phase asynchronous motor can meet the instantaneous change from the high to low speed; the frequency does not need to be changed; and the special needs of the user are met.
Description
Technical field
The present invention relates to a kind of distal pole than threephase asynchronous machine, belong to mechanical & electrical technology field.
Background technology
Threephase asynchronous machine is a kind of new energy-conserving product, and this motor has significant energy-saving effect for continuous operation, occasion that load factor is higher.Abroad develop one after another and produced this motor from middle nineteen seventies Ge great manufactory, China, under the support of Bureau of Energy of national Economic and Trade Commission and Machinery Ministry science and technology department, electrician office, is organized Beijing, Dalian, Shanghai, Boshan Deng Shiyujia electrical machinery plant and Huazhong Institute of Technology in 83-84 design and has been trial-produceed successfully YX3 series of high efficiency rate threephase asynchronous by Machinery Ministry Shanghai Electric Appliances Science Inst.
Threephase asynchronous machine runnability is good, and can save various materials.Press the difference of rotor structure, threephase asynchronous can be divided into two kinds of cage and Wound-rotor types.The Induction Motor Structure of cage rotor is simple, reliable, lightweight, low price, is widely used, and its major defect is speed governing difficulty.The rotor of wound three-phase asynchronous motor is the same with stator to be also provided with three phase windings and to be connected with outside rheostat by slip ring, brush.Standardsizing rheostat resistance can improve the starting performance of motor and regulate the rotating speed of motor.
Machine operation principle is: when the threephase stator winding of motor, pass into after three-phase symmetrical alternating current, to produce a rotating magnetic field, this rotating magnetic field cutting rotor winding, thereby in rotor winding, produce induced current, the rotor conductor of current-carrying will produce electromagnetic force under the effect of stator rotating magnetic field, thereby on machine shaft, form electromagnetic torque, drive motor rotation, and motor direction of rotation is identical with rotating magnetic field direction.
At present, existing threephase asynchronous machine only has 4/2,6/4, and the double-speed motor of 8/4,8/6 ratio such as proximal pole such as grade, without the motor of distal pole ratio, has greatly limited the range of application of threephase asynchronous machine.
Summary of the invention
The object of the invention is for solve in prior art threephase asynchronous machine without distal pole than the defect of model, provide a kind of distal pole to solve the problems referred to above than threephase asynchronous machine.
To achieve these goals, technical scheme of the present invention is as follows:
A kind of distal pole, than threephase asynchronous machine, comprises stator core, and described stator core is provided with the first winding and the second winding, between the upper strata inserting slot that is arranged at winding slot of described the first winding, and described the second winding and being arranged between lower floor's winding slot.
In the present invention, the number of poles ratio of described the first winding and the second winding is 8/2,12/2,16/2,12/4 or 16/4.
In the present invention, also comprise rotor, the tail end of described rotor is provided with fan blade.
In the present invention, also comprise rear end cap, described rear end cap is provided with fan housing.
In the present invention, between described fan blade and rotor, be provided with shaft block ring.
The invention has the beneficial effects as follows: can meet high speed to the transformation of low speed moment, not need to realize by changing frequency, can meet user's specific demand.
