A center position of the punching sheet body is provided with a punching sheet inner hole. A plurality of punching sheet grooves which are equally divided on the circumference are provided around the punching sheet inner hole. The punching sheet grooves are arranged into four punching sheet groove groups. The four punching sheet groove groups are arranged to be symmetric with respect to a transverse central line and a longitudinal central line. Each punching sheet groove group comprises a first punching sheet groove, a second punching sheet groove, and a third punching sheet groove. The height of the first punching sheet groove is less than the height of the second punching sheet groove, and the height of the second punching sheet groove is less than the height of the third punching sheet groove. According to the utility model, the motor stator punching sheets use three groove structures, the groove shape utilization rate after windings use sine distribution is solved, the harmonic wave magnetic potential can be weakened, the iron loss can be reduced by fully using silicon steel plates, and the using reliability and security of a compressor can be improved.
Description
Technical field
The utility model relates to the stator punching on a kind of motor.
Background technology
Motor plays very important effect in compressor, its startup ability and runnability affect environment for use and the energy consumption requirement of compressor, the performance index such as the load capacity of compressor, noise, vibration to a great extent.Motor is the power resources of compressor suction and discharge actings, also is simultaneously that country advocates low-carbon (LC), efficient, energy-conservation critical component, also is the runnability that affects compressor, user's matching performance requirement.Consider use field and the scope of design of compressor, original compressor electric motor adopts copper cash sulculus type stator punching mostly, along with constantly riseing of World Copper valency, the cost pressure of compressor is more and more severeer, reduces the vital task that cost has become each Compressors Factory.In addition, existing copper cash motor is machine and rolls off the production line, and groove area is little, along with continuous popularization and the utilization of electric machine with aluminium winding, by original stator punching groove design, will cause the winding wire load not, the unfavorable factors such as heating increases, and efficient is on the low side are difficult to satisfy the performance requirement of compressor.Above situation has caused disadvantageous factor to the overall performance (runnability, vibration, noise, low-voltage startup, fail safe etc.) of compressor.
Summary of the invention
In order to overcome above-mentioned deficiency of the prior art, the utility model provides a kind of stator punching that designs the compressor electric motor of different punching trench structures.
The technical scheme in the invention for solving the technical problem is:
A kind of stator punching of compressor electric motor, comprise the punching body, described punching body center arranges the punching endoporus, be provided with some punching grooves around the punching endoporus by circumference equal dividing, described punching groove is set to four groups of punching groove groups, described four groups of punching groove groups are cross central line and longitudinal centre line is symmetrical, described every group of punching groove includes the first punching groove, the second punching groove and the 3rd punching groove, the height of described the first punching groove is less than the height of the second punching groove, and the height of described the second punching groove is less than the height of the 3rd punching groove.
As preferably, it is first a punching groove, second a punching groove and four the 3rd punching grooves that every group of punching groove arranged successively.
As preferably, at the adjacent punching tooth that is provided with of each described punching groove, described punching tooth is parallel teeth, and the width of described parallel teeth is all identical.
As preferably, the punching groove is peariform slot, and each punching groove is communicated with the punching endoporus by notch, and the width of the notch of described punching groove is all identical.
The punching groove is arranged to three kinds of sizes, the 3rd punching groove grooved is maximum, the first punching groove grooved is minimum, and the second punching groove is placed in the middle, and when distributing, symmetrical with cross central line and longitudinal centre line respectively, the punching grooved adopts 24 grooves, 3 trench structures, solved the grooved utilance after winding adopts Sine distribution, can slacken harmonic magnetic potential, core loss of grain orientation silicon steel sheet can be taken full advantage of again, the technological feasibility of the copper factor that rolls off the production line can be solved simultaneously.Simultaneously the punching grooved is amplified, the wire limited load is descended, reduce the winding wire loss, the runnability of motor when rated power improved.In addition, the adjacent punching tooth that is provided with of each described punching groove, the punching tooth is parallel teeth, and the width of parallel teeth is all identical, and each punching groove is communicated with the punching endoporus by notch, the width of the notch of punching groove is all identical, suitable notch height and oblique shoulder height degree can solve because tooth section magnetic potential skewness causes pulsating magnetic potential, have reduced simultaneously the magnetizing current of motor, can slacken harmonic magnetic potential and reduce copper olse, can take full advantage of core loss of grain orientation silicon steel sheet again.
The beneficial effects of the utility model are: the utility model makes motor stator punching adopt three kinds of trench structures, solved the grooved utilance after winding adopts Sine distribution, can slacken harmonic magnetic potential, can take full advantage of core loss of grain orientation silicon steel sheet again, and adopt large trench structure, effective copper loss of wire is reduced, improve the mechanical efficiency of compressor electric motor, winding wire diameter can be put slightly, can improve dependability and the fail safe of compressor.
