Abstract
The utility model relates to a rotor punching for an electric motor, which comprises a rotor punching body; and 40 rotor punching slots are arranged on the rotor punching body. As for the rotor punching slots, the width of the rotor notch is 1.5 millimeters, the first rotor slot width is 3.4 millimeters, the second rotor slot width is 12 millimeters, the rotor slot bottom width is 5.7 millimeters, the shoulder angle of the rotor slot is minus 20 degrees, the height of the rotor notch is 2 millimeters, the first rotor slot height is 17.5 millimeters, and the second rotor slot height is 40 millimeters. Only the punching tool of the rotor punching needs to be changed, and the original assembling method of the motor is not changed; the rotor punching is applied to a rotor core of an efficient motor, the center height of which is 355-2, can improve the efficiency of the electric motor, and has low electromagnetic noise, small starting current and high torque in the long-term using process.
Description
Technical field
The utility model relates to a kind of rotor punching of motor, specifically is used for the rotor core that the high efficiency motor height of center is the 355-2 utmost point.
Background technology
Along with the national economic development, deficient gradually and its inevitable pollution of traditional energy more and more is restricted its application, for making motor product can occupy bigger market share, development efficiency motors stator punching, reaching the cost that cuts down the consumption of energy and be client's save money, is the effective ways of realizing this goal at present for current low-carbon economy brings the productivity of sustainable development, adaptation client's requirements at the higher level.
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 355-2 utmost point motor is more outstanding.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby provide a kind of rotor punching of motor, this punching is used for the rotor core that the high efficiency motor height of center is the 355-2 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 the technical scheme that the utility model provides, a kind of rotor punching of motor comprises the rotor punching body, and described rotor punching body is provided with 40 rotor punching grooves.
Described rotor punching grooved rotor slot opening b02 is: 1.5mm; The first rotor groove width br1 is: 3.4mm; The second rotor groove width br3 is: 12mm; Rotor bottom width br4 is: 5.7mm; Rotor shoulder slope angle is counted zs2 :-20 degree; The high hr0 of rotor notch is: 2mm; The high hr12 of the first rotor groove is: 17.5mm; The high hr3 of second rotor is: 40mm.
Compared with the prior art the utility model has the following advantages:
The utility model 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 355-2 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.
