Abstract
The utility model relates to air condition compressor motor equipment, in particular to a stator appearance structure of an air condition compressor, aiming to provide a deformed motor stator punching sheet which saves materials and improves the motor property. The deformed motor stator punching sheet is a quadrangle and provided with 28 slots which are distributed in bilateral symmetry. In the utility model, slot-shaped matching of the 28 slots is adopted, which ensures that a stator tooth is exactly positioned at a mounting hole, thereby too high magnetic density caused by too small magnetic circuit area is avoided, and the motor efficiency is improved.
Description
Technical field
The utility model relates to a kind of compressor of air conditioner motor device, relates to a kind of stator contour structures of compressor of air conditioner motor especially.
Background technology
Compressor of air conditioner is the heart in the refrigerating system, and the performance of its drive motors and quality are very important.That designs this motor will make it stably work in the compressor midium or long term, can reach best coupling with compressor body again, thereby improve the performance index of compressor, obtain best economic benefit.The size of stator punching internal diameter will influence the tooth portion of stator and rotor, the close ratio of magnetic of yoke portion.In order to save material, stator punching adopts the profile of round butt more, guarantees that at the butt place yoke is high equal, also has and adopts the sulculus design herein.
In existing technology, the stator of refrigerator refrigeration compressor motor all is the design of five equilibrium groove, the punching design of 16 vats, 8 sulculuses collocation.Adopt the punching of this designed motor one vat just in time to be arranged, make that the magnetic circuit area at this place is too narrow and small, thereby cause the magnetic at this place close very high, make whole motor properties can not get tangible raising at the installing hole place.And adopt the design of 24 grooves, motor dead point when starting is more, the illusion that very easily causes whole compressor to be stuck, thus cause motor normally not start, the abnormal working position of creeping at low-speed stage causes the major safety risks of burn-down of electric motor easily for a long time.And adopted the compressor of the motor that 24 grooves cooperate, and its COP value is lower, and the highest only can reaching about 1.80 is unfavorable for the measure of the energy-saving and emission-reduction of China's proposition.
The utility model content
The purpose of this utility model is to provide a kind of special-shape motor stator punching of saving material, improving motor performance.
The technical scheme that realizes the utility model purpose is, a kind of special-shape motor stator punching, and the said stator punching is a quadrangle, has 28 grooves, and 28 grooves are left-right symmetric and distribute.
Benefit of the present utility model is to adopt the grooved of 28 grooves to cooperate, and makes that being positioned at the installing hole place is a stator tooth just in time, thereby has avoided this place to cause magnetic close too high because of the magnetic circuit area is too small, has improved electric efficiency; Adopt 28 groove groove numbers to cooperate, make that the magnetic of stator teeth is close further to reduce, reduced electromagnetic noise, further improved efficiency of motor; Adopt eccentric tooth design, guaranteed the reasonability of magnetic circuit area fully, the maximized close too high situation of local magnetic of having stopped has reduced electromagnetic noise, has improved electric efficiency; Adopt the motor of the eccentric teeth groove type collocation of 28 grooves, on motor noise and electric efficiency, remarkable advantages is arranged than other motors.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
See Fig. 1, the punching of this air-conditioning compressor is a quadrangle, has 28 grooves 1, and is the left-right symmetric structure, and outline has adopted eccentric tooth design, has guaranteed the reasonability of magnetic circuit area fully, the maximized close too high situation of local magnetic of having stopped.Adopt 28 groove groove numbers to cooperate, make that the magnetic of stator teeth is close further to reduce, reduced electromagnetic noise, further improved efficiency of motor.
