Abstract
一种低噪音定子铁芯冲片，属电机用配套部件的制造技术领域，主要由定子铁芯冲片(3)，开设于定子铁芯冲片(3)底部极靴上的虚拟槽等构成；根据电机极数不同，可开设1～3个虚拟槽。设计合理，结构简单，从电机内部着手，通过在定子铁芯极靴上添加虚拟槽使齿谐波的频率变高，幅值降低，从而在整体上降低噪音，能有效改善电机的运行噪音，提高产品质量。
A low-noise stator core punching sheet belongs to the technical field of manufacturing supporting parts for motors, and is mainly composed of a stator core punching sheet (3), a virtual slot provided on the pole shoe at the bottom of the stator core punching sheet (3), etc.; 1 to 3 virtual slots can be provided according to the number of motor poles. The design is reasonable and the structure is simple. Starting from the inside of the motor, the frequency of tooth harmonics is increased and the amplitude is reduced by adding virtual slots on the stator core pole shoe, thereby reducing noise as a whole, effectively improving the running noise of the motor and improving product quality.
Description
Technical field
The utility model relates to a kind of low-noise stator core stamping sheet, belongs to the manufacturing technology field of motor with matching component.
Background technology
Along with growth in the living standard, people are also more and more higher to the quiet requirement of air-conditioning, and the air-conditioning noise has part to come from motor rotation, the noise source of motor has a variety of, for reducing the noise that produces when motor moves, prior art by seek solution route on parts such as rotor, installation foot, provides a kind of mounting bracket that reduces motor noise as Chinese patent ZL200720105627.9 mostly.But do not see the improvement report from the stator structure.
Summary of the invention
The purpose of this utility model provides a kind of reasonable in design, and is simple in structure, can effectively improve the operation noise of motor, the low-noise stator core stamping sheet that improves the quality of products.
The utility model is a low-noise stator core stamping sheet, comprises stator core stamping sheet, it is characterized in that offering virtual groove on the pole shoe of stator core stamping sheet bottom.
The offer quantity of described virtual groove on pole shoe can be 1～3.
During machine operation, every harmonic wave that comprises in the air gap field waveform that extremely descends is by the fourier progression expanding method amplitude height that then frequency is low; The amplitude that frequency is high is low.And amplitude strong noise is big more more.The utility model provides a kind of novel approach that reduces noise for motor, sets about from motor internal, and by add the frequency gets higher that virtual groove makes slot ripples on the stator core pole shoe, amplitude reduces, thereby reduces noise on the whole.Can select to offer 1～3 virtual groove according to the model difference of idle call motor simultaneously,, improve the quality of product so that the operation noise problem of motor is further improved.
Description of drawings
Fig. 1 is the overall structure schematic diagram that the utility model is offered 1 virtual groove;
Fig. 2 is the overall structure schematic diagram that the utility model is offered 2 virtual grooves.
Embodiment
The utility model is opened in the formations such as virtual groove on the stator core stamping sheet 3 bottom pole shoes mainly by stator core stamping sheet 3.
According to the motor pole number difference, can offer 1～3 virtual groove, as offering 1 virtual groove 1, on 6 utmost point machine stator core stampings, 3 bottom pole shoes, evenly offer 2 virtual grooves 2 in the center of 8 utmost point machine stator core stampings, 3 bottom pole shoes.Add man-hour, make mould according to designing requirement earlier, go out desired punching again, in the punching process,, laminate out desired stator core automatically by Equipment Control.
Claims (2)
1, a kind of low-noise stator core stamping sheet comprises stator core stamping sheet (3), it is characterized in that offering virtual groove on the pole shoe of stator core stamping sheet (3) bottom.
2, by the described low-noise stator core stamping sheet of claim 1, it is characterized in that the offer quantity of described virtual groove on pole shoe is 1～3.
