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, the 3rd punching groove, the 4th punching groove and the 5th punching groove, the height of described the first punching groove is less than the height of the second punching groove, the height of described the second punching groove is less than the height of the 3rd punching groove, the height of described the 3rd punching groove is less than the height of the 4th punching groove, and the height of described the 4th punching groove is less than the height of the 5th punching groove.
As improvement, it is first a punching groove, second a punching groove, two the 3rd punching grooves, the 4th a punching groove and the 5th a punching groove 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 five kinds of sizes, the 5th punching groove grooved is maximum, the first punching groove grooved is minimum, and when distributing, arrange successively is first a punching groove, second a punching groove, two the 3rd punching grooves, the 4th a punching groove and the 5th a punching groove, and symmetrical with cross central line and longitudinal centre line respectively, the punching grooved adopts 24 grooves, 5 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, solved motor coil line wire diameter, 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 a of the notch of punching groove is all identical, suitable notch height b and oblique shoulder height degree c 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 five 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.
