Description
technical field
The utility model relates to a kind of motor, particularly three-phase alternating-current motor.
background technology
Known three-phase alternating-current motor, the iron core of stator has countless teeth groove in annulus, and wire is symmetrical embedding around in groove.This structure makes wire be placed in rotor rotating magnetic field, when making motor, because wire is produced back electromotive force by the cutting of rotor rotating magnetic field, has reversible usability.Can say so, when making motor, efficiency 100% also does generator efficiency 100% simultaneously, and both cancel out each other.
The utility model aims to provide a kind of new three-phase alternating-current motor, can overcome above-mentioned phenomenon.
summary of the invention
In order to realize above-mentioned same machine, to do motor efficiency high, does generator efficiency low, thus improve the object of energy conversion efficiency.The solution of the present invention is: stator structure is made up of (1), insulating barrier (2) unshakable in one's determination, coil (3), charges (4), casing, end cap and bearing.Described iron core (1) connects several T-shaped pin in annulus, Q type cavity is formed between two T-shaped pin, there is small―gap suture at bipod place, after lining insulating layer (2), coil (3) is concentrated and is worn around in Q type cavity, and Q type cavity remainder is embedding full by charges (4).
This structure has two large advantages: 1, the average magnetomotive force of identical ampere-turn electric current generation, coil is concentrated and worn around symmetrical embedding more much higher in groove than wire.2, the high permeability of T-shaped iron core, the high magnetic resistance of Q type cavity and charges defines magnetic screen to coil, and the magnetic line of force of rotor rotating magnetic field is difficult to remove cutting stator coil completely, and back electromotive force diminishes; Iron core, cavity and charges do not produce loss to the magnetic line of force of stator conductor and the effect of rotor.Can say so, when making motor, also do generator efficiency is significantly less than 100% to efficiency 100% simultaneously, and both can not offset.
According to such scheme, Novel three-phase alternating-current motor of the present utility model is different from known three-phase alternating-current motor.Below in conjunction with the unshakable in one's determination embodiment of diagram to the Novel three-phase alternating-current motor stator of a pair magnetic pole, scheme is described in detail.

embodiment
The silicon steel sheet shape of (1) unshakable in one's determination is connect 6 identical uniform T-shaped pin in annulus to form, and adjacent two T-shaped pin and circle ring inner wall form Q type cavity, and there is small―gap suture at bipod place.T-shaped pin intrados is teeth groove type shape, and teeth groove number is 3---and 5, best 4.The interior arc length of T-shaped pin and gap sum are 60 °.Silicon steel sheet stack synthesis core length (paint film sheet) of countless iron core (1).Respectively put one at two ends unshakable in one's determination and make insulation spacer with the glass-fiber-plate of same shape unshakable in one's determination.Fixed iron core and pad.Insulating barrier (2) lining is at Q type cavity inner wall.After insulation values is up to standard, coil (3) passes from a Q type cavity, penetrates from another Q type cavity, forms closed-loop path, and tight note circle ring inner wall insulating barrier.Q type cavity remainder is embedding full by charges (4).Charges (4) are not magnetic conduction, non-conductive, resistant to elevated temperatures solid matter.Annulus is become at end plate two end plate after three-phase coil insulate separately.Three equidirectional conductor in parallel of the coil in interval are public zero curve together, and another three taps are A, B, C three-phase, and difference is 120 °.Coil and paint-dipping drying unshakable in one's determination.
A pair magnetic pole is 6 T-shaped pin, and two pairs of magnetic poles are 12 T-shaped pin, by that analogy.
Stator structure is made up of (1), insulating barrier (2) unshakable in one's determination, coil (3), charges (4), casing, end cap and bearing.
Rotor is any one in squirrel-cage or excitation-type or magneto.When using cage rotor, the ability of squirrel-cage bar generation current need increase 80%.
(1) unshakable in one's determination is contained in casing.Rotor is connected with casing with end cap by bearing.
The magnetomotive force that stator produces after concentrating the coil of coiling (3) galvanization, the annular of direction centered by wire, through magnetic circuit be: T-shaped pin iron core-air gap-rotor-air gap-T-shaped pin iron core-annulus (yoke) forms closed-loop path, and Q type cavity (charges) does not almost hinder it.Three-phase electricity produces rotating magnetic field, and the magnetic field that rotor induced current produces always hinders it to rotate, thus rotor is pushed and rotates.The point of stator and rotor active force and reaction force occurs in the T-shaped pin inner surface of stator and rotor outer surface, the magnetic line of force (direction of power) is between both air gaps, the size of active force is relevant with magnetic flux density and surface area, and the placement location of these and coil (3) has nothing to do.The rotating magnetic field of rotor and the rotating magnetic field of stator are had an effect after power, its flux circuit is walked therefrom, pass through if it walks Q type cavity (charges) totally, must cutting stator coil (3) totally, produce the back electromotive force the same with known motor, but, the magnetizing mediums of Q type cavity is air or non-magnetic charges (4), magnetic resistance is that the number of T-shaped pin iron core is dry doubly to tens thousand of times, therefore, its the flux circuit overwhelming majority is walked the little T-shaped pin iron core of magnetic resistance and is not walked the large Q type cavity of magnetic resistance and charges, like this, the magnetic flux of sectioned coil (3) significantly reduces, side back electromotive force significantly reduces.
The size of motor force and current related, rotating speed speed is relevant with frequency, has nothing to do with voltage.The threephase asynchronous of such as power output 1000W, back electromotive force be 100% known electric motor need phase voltage 220 volts, electric current 2.2 is pacified; The novel motor that back electromotive force is significantly less than 100% only needs phase voltage 110 volts, and electric current 2.2 is pacified.Visible Novel three-phase alternating-current motor significantly improves than known three-phase alternating-current motor energy conversion efficiency.
The machine is unfit to do generator.Asynchronous motor or the synchronous motor of large, medium and small different model can be made, be applicable to the occasion that all need threephase motor to drag.Structure is simple, and batch production easily.
