Abstract
The invention relates to a rotor sheet of a motor, which comprises a rotor sheet body, wherein the rotor sheet body has 40 rotor sheet slots. In the rotor sheet slots, the width of rotor notches is 1.5 millimeters, a first rotor slot width is 3.4 millimeters, a second rotor slot width is 12 millimeters, the bottom width of the rotor slots is 5.7 millimeters, the shoulder angle of the rotor slots is -20 DEG, the height of the rotor notches is 2 millimeters, a first rotor slot height is 17.5 millimeters and a second rotor slot height is 40 millimeters. In the invention, only the stamping mold of the rotor sheet instead of the original assembly mode of the motor is changed; the sheet is used in a rotor iron core of a motor with a central height of 355 millimeters and grade-2 rotation speed for improving efficiency of the motor; and in the long-term use of the rotor sheet, the electromagnetic noise is small, the starting current is small and the torque is large.
Description
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 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 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 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 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 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 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 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.
Description of drawings
Fig. 1 is the present invention's 40 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 40 grooves 2.The present invention program does not change original fit of motor.
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.
