Abstract

The invention relates to a rotor punching plate of a motor. The rotor punching plate comprises a rotor punching plate body, and the rotor punching plate body is provided with 28 rotor punching plate grooves. In the rotor punching plate grooves, b02 is 1 millimeter; br1 is 2.6 millimeters, br3 is 5.8 millimeters, and br4 is 2.2 millimeters; zs2 is 35 degrees; hr0 is 0.8 millimeter; hr12 is 7 millimeters; and hr3 is 15.9 millimeters. Only a punching die for the rotor punching plate is changed, but the original assembly mode of the motor is not changed; the punching plate used in a rotor core with efficient motor center height of 132-2 poles can improve the efficiency of the motor; and the punching plate has low electromagnetic noise, low starting current and large torque in long-term use.

Description

A kind of rotor punching of motor
Technical field
The present invention relates to a kind of rotor punching of motor, specifically be used for the rotor core that the high efficiency motor height of center is the 132-2 utmost point.
Background technology
In the current society of global resources scarcity, people strengthen day by day to the consciousness of energy-saving and emission-reduction low-carbon (LC) life, and country is at present also in energetically promotion energy-saving and emission-reduction, and by improving the mode of motor efficiency, are one of approach of realizing this goal.Be widely used in the motor in the fields such as industry, agricultural, commerce, building industry and traffic at present, defective such as ubiquity efficient is low, energy consumption is big can not satisfy the requirement of efficient and energy-saving and emission-reduction.
Rotor punching is the key components and parts in the motor, its material, interior round size, excircle dimension, flute profile size, what etc. efficiency of motor is had direct influence.And use maximum Y2 series motor in the market, its rotor punching can't reach the purpose that improves electric efficiency, and realize that in long-term use it also exists defectives, particularly height of center such as electromagnetic noise is big, starting current is big, torque is little is that its above-mentioned defective of 132-2 utmost point motor is more outstanding.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, thereby a kind of rotor punching of motor is provided, this punching is used for the rotor core that the high efficiency motor height of center is the 132-2 utmost point, can improve the efficient of motor, in long-term use, electromagnetic noise is little, starting current is little, and torque is big.
According to technical scheme provided by the invention, a kind of rotor punching of motor comprises the rotor punching body, and described rotor punching body is provided with 28 rotor punching grooves.
B02 is 1mm in the described rotor punching flute profile; Br1 is 2.6mm; Br3 is 5.8mm; Br4 is 2.2mm; Zs2 is 35 degree; Hr0 is 0.8mm; Hr12 is 7mm; Hr3 is 15.9mm.
Compared with the prior art the present invention has the following advantages:
The present invention only need change the diel of rotor punching, does not change original fit of motor; This punching is used for the rotor core that the high efficiency motor height of center is the 132-2 utmost point, can improve the efficient of motor, and in long-term use, electromagnetic noise is little, starting current is little, and torque is big.
Description of drawings
Fig. 1 is the present invention's 28 groove rotor punching structural representations.
Fig. 2 is a rotor punching flute profile dimensional drawing of the present invention.
Embodiment
Embodiment during following the present invention incites somebody to action in conjunction with the accompanying drawings is further described:
The present invention only need change the diel of rotor punching, goes out rotor punching body 1 with the 50WW470 cold-reduced silicon sheet on punch press, and rotor punching body 1 is provided with 28 grooves 2.The present invention program does not change original fit of motor.
In the described rotor punching grooved: rotor slot opening b02 is 1mm; Rotor groove width 1 br1 is 2.6mm; Rotor groove width 2 br3 are 5.8mm; Rotor bottom width br4 is 2.2mm; It is 35 degree that rotor shoulder slope angle is counted zs2; The high hr0 of rotor notch is 0.8mm; High 1 hr12 of rotor is 7(mm); High 2 hr3 of rotor are 15.9mm.
