Abstract

The invention relates to a rotor punching sheet of a four-pole motor. The rotor punching sheet comprises a rotor punching sheet body, wherein 40 rotor punching sheet grooves are uniformly punched in the outer circumference of the rotor punching sheet body; the notch width b02 of each punching sheet groove is 1.5 millimeters; the groove width br1 of a first rotor punching sheet groove is 3.5 millimeters; the groove width br3 of a second rotor punching sheet groove is 4.8 millimeters; the groove bottom width br4 of each punching sheet groove is 2.4 millimeters; the groove shoulder rake angle zs2 of each punching sheet groove is 30 degrees; the notch height hr0 of each punching sheet groove is 0.8 millimeter; the groove height hr12 of the first rotor punching sheet groove is 12.2 millimeters; and the groove height hr3 of the second rotor punching sheet groove is 22.6 millimeters. According to the invention, the rotor punching sheet has the advantages of no change of the original assembly way of the motor, good adaptability, applicability to a rotor core of an efficient four-pole motor of which the center height is 180, low electromagnetic noise, small starting current, large torque and capability of effectively increasing the motor efficiency.

Description

A kind of rotor sheet of four-pole motor
Technical field
The invention belongs to the motor technology field, be specially a kind of rotor sheet of four-pole motor, be specially adapted in the four very high performance electric machine rotor iron cores of 180 height of centers.
Background technology
At present, widely used motor in fields such as industry, agricultural, commercial, building industry and traffic, defective such as ubiquity efficient is low, energy consumption is big can not satisfy energy-efficient requirement.
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.Use more Y2 series motor in the market; Its rotor punching can't reach the purpose that improves electric efficiency; And find 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 180-4 utmost point motor is more outstanding.
Summary of the invention
The objective of the invention is to overcome the deficiency that exists in the prior art, a kind of motor rotor punching slice is provided, this punching electromagnetic noise is little, starting current is little, and torque is big, can improve the efficient of motor.
According to technical scheme provided by the invention: a kind of four-pole motor rotor punching, comprise the rotor punching body, be characterised in that: 40 rotor punching grooves evenly are set on the external circumference of said rotor punching.
As further improvement of the present invention, the slot opening b02 of said each punching groove is 1.5mm; The first rotor punching groove groove width br1 is 3.5mm; The second rotor punching groove groove width br3 is 4.8mm; The wide br4 of punching groove bottom land is 2.4mm; It is 30 degree that punching groove groove shoulder slope angle is counted zs2; The high hr0 of punching groove notch is 0.8mm; The high hr12 of the first rotor punching groove groove is 12.2mm; The high hr3 of the second rotor punching groove groove is 22.6mm.
The present invention compared with prior art, advantage is: the present invention does not change original fit of motor, and applicability is good; And this punching is used for the rotor core that the high efficiency motor height of center is the 180-4 utmost point; Electromagnetic noise is little, starting current is little, and torque is big, can effectively improve electric efficiency.
Description of drawings
Fig. 1 is a rotor punching structural representation of the present invention.
Fig. 2 is Fig. 1 rotor punching groove sketch map.
Embodiment
Below in conjunction with concrete accompanying drawing and embodiment the present invention is described further.
Like Fig. 1, shown in Figure 2, said a kind of motor rotor punching slice comprises rotor punching body 1, and being uniformly distributed with punching out on said rotor punching body 1 excircle has 40 rotor punching grooves 2.
The slot opening b02 of said each rotor punching groove 2 is 1.5mm; The first rotor punching groove groove width br1 is 3.5mm; The second rotor punching groove groove width br3 is 4.8mm; The wide br4 of punching groove bottom land is 2.4mm; Punching groove groove shoulder slope angle zs2 is 30 degree; The high hr0 of punching groove notch is 0.8mm; The high hr12 of the first rotor punching groove groove is 12.2mm; The high hr3 of the second rotor punching groove groove is 22.6mm.
The present invention changes the diel of rotor punching, on punch press, goes out the rotor punching body with the 50WW470 cold-reduced silicon sheet, 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 180-4 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.
