Abstract
The invention relates to a stator and rotor sheet of a motor, and provides a low-noise stator and rotor sheet of a ten-pole three-phase asynchronous motor. The low-noise stator and rotor sheet comprises a stator sheet body and a rotor sheet body. The stator sheet body is in an annular shape, 48 wire-embedded grooves are formed in the inner circle of the annular stator sheet body, the rotor sheet body is in an annular shape, and 58 notches are formed in the outer circle of the annular rotor sheet body. The electromagnetic noise of the motor can be lowered and the start performance of the motor can be improved by improving the groove match between a stator and a rotor of the motor.
Description
Technical field
The present invention relates to a kind of stator and rotor punching of motor, particularly relate to a kind of low noise stator and rotor punching of 10 pole three phase asynchronous motors.
Background technology
Electromagnetic noise is one of Main Noise Sources of motor, and in electrical machine with large number of poles, it is particularly outstanding that electromagnetic noise seems, if design improperly, electromagnetic noise will be fairly obvious, becomes the main noise source over other noise (ventilating and machinery noise).The electromagnetic noise of motor is mainly the stator vibration producing due under the effect at radial electromagnetic force ripple, causes surrounding air pulsation and the gas that causes carries noise.It is wherein, reasonable, appropriate that must to select motor stator rotor to coordinate be the important means of controlling electromagnetic noise.In existing small-sized 10 pole three phase asynchronous motors, generally do not have special-purpose groove to coordinate, stator and rotor groove number mostly is uses existing 6 or 8 utmost point motor stampings, it is 36/32,36/33,48/44 that groove coordinates, 54/44,54/50 etc., while being applied in 10 utmost point motor, can produce electromagnetic noise strong, and the startability of motor is also undesirable.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of 10 pole three phase asynchronous motor low noise stator and rotor grooves and coordinates, and effectively reduces the electromagnetic noise of motor, and improves the startability of motor.
For realizing above-mentioned technical purpose, the technical solution used in the present invention is: a kind of low noise stator and rotor punching of 10 pole three phase asynchronous motors, comprise stator punching body and rotor punching body, described stator punching body is circular, the inner ring of described circular punching body is provided with line embedding groove, and the quantity of described line embedding groove is 48; Described rotor punching body is circular, and the outer ring of described circular punching body is provided with notch, and notch quantity is 58.
Line embedding groove on described stator punching body is uniformly distributed along the punching body center of circle.
Line embedding groove on described stator punching body has a closing on the inner ring of punching body, and line embedding groove is Ω shape.
Notch on described rotor punching body is uniformly distributed along the punching body center of circle.
Notch on described rotor punching body has a closing on the external circle of punching, and closing in size is less than notch inside dimension.
This invention contrast prior art has following beneficial effect: by improving the groove of motor stator and rotor, coordinate, can reduce the electromagnetic noise of motor, improve the startability of motor.
Accompanying drawing explanation
The structural representation that accompanying drawing 1 is stator punching.
The structural representation that accompanying drawing 2 is rotor punching.
Embodiment
Below in conjunction with drawings and Examples, the present invention will be further described.
A low noise stator and rotor punching for 10 pole three phase asynchronous motors, the structure of stator punching is shown in shown in accompanying drawing 1, and it is circular, and the inner ring of described circular punching body is provided with line embedding groove 1, and the quantity of line embedding groove is 48, along the punching body center of circle, is uniformly distributed.As shown in Figure 1, line embedding groove 1 has a closing on the inner ring of punching body, and line embedding groove is Ω shape.
The structure of rotor punching is shown in shown in accompanying drawing 2, and described rotor punching body is circular, and the outer ring of described circular punching body is provided with notch 2, and notch quantity is 58, along the punching body center of circle, is uniformly distributed.As shown in Figure 2, notch has a closing on the external circle of punching, and closing in size is less than notch inside dimension.
The stator providing according to this embodiment, rotor punching on H160-10 5.5KW Motor Foundation, do respectively rotor groove coordinate be 48/44 and rotor groove to coordinate be 48,/58 two kind of contrast scheme, wherein two kinds of stator schemes are identical.
It is that the cooperation of 48/44,2# model machine groove is 48/58 that 1# model machine groove coordinates.After model machine has been assembled, carry out noise and startability test, test result is as follows: 48/58 groove coordinated scheme reduces by 8 decibels of noises compared with 48/44 groove coordinated scheme, and detent torque improves 16.7%, and effect is remarkable.
| Motor numbering | Groove coordinates | Noise LW dB (A) | Tst/Tn | Ist/In |
| 1# | 48/44 | 75 | 1.68 | 4.2 |
| 2# | 48/58 | 63 | 1.96 | 4.4 |
