Abstract

The utility model relates to a four-pole motor rotor punching sheet which comprises a rotor punching sheet body. An outer periphery of the rotor punching sheet body is uniformly distributed and punched with 40 rotor punching sheet grooves. A groove mouth width b02 of each punching sheet groove is 1.5 mm. A groove width br1 of a first rotor punching sheet groove is 3.5 mm. A groove width br3 of a second rotor punching sheet groove is 4.8 mm. A groove bottom width br4 of the punching sheet groove is 2.4 mm. A groove shoulder oblique angle zs2 of the punching sheet groove is 30 degrees. The groove mouth height hr0 of the punching sheet groove is 0.8 mm. A groove height hr12 of the first rotor punching sheet groove is 12.2 mm. A groove height hr3 of the second rotor punching sheet groove is 22.6 mm. According to the four-pole motor rotor punching sheet, an original assembly mode of a motor is not changed, the adaptability is good, the punching sheet is used in a rotor iron core of a high efficiency four-pole motor with a center height of 180mm, the electromagnetic noise is low, the starting current is small, the torque is large, and the efficiency of the motor can be effectively raised.

Description

A kind of rotor sheet of four-pole motor

Technical field

The utility model belongs to the motor technology field, is specially a kind of rotor sheet of four-pole motor, in the high four very high performance electric machine rotor iron cores in 180 centers that are specially adapted to.

Background technology

At present, widely used motor in the fields such as industry, agricultural, business, building industry and traffic, the defective such as ubiquity efficient is low, energy consumption is large can not satisfy energy-efficient requirement.

Rotor punching is the key components and parts in motor, its material, inner circle size, excircle dimension, flute profile size, what etc. the efficient of motor is had direct impact.Use in the market more Y2 Series Motors, its rotor punching can't reach the purpose that improves electric efficiency, and find that in long-term use procedure also there are the defectives such as electromagnetic noise is large, starting current is large, torque is little in it, particularly the center height is that its defects of 180-4 utmost point motor is more outstanding.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of motor rotor punching slice is provided, and this punching electromagnetic noise is little, starting current is little, and torque is large, can improve the efficient of motor.

The technical scheme that provides according to the utility model: 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 described rotor punching.

As further improvement of the utility model, the slot opening b02 of described 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; Punching groove groove shoulder slope angle number 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 second high hr3 of rotor punching groove groove is 22.6mm.

The utility model compared with prior art, advantage is: the utility model does not change original assembling mode of motor, and applicability is good, and it is the rotor core of the 180-4 utmost point that this punching is used for high efficiency motor center height, electromagnetic noise is little, starting current is little, and torque is large, can effectively improve electric efficiency.

Embodiment

The utility model is described in further detail below in conjunction with concrete drawings and Examples.

As shown in Figure 1 and Figure 2, described a kind of motor rotor punching slice comprises rotor punching body 1, and on described rotor punching body 1 excircle, uniform punching has 40 rotor punching grooves 2.

The slot opening b02 of described 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 second high hr3 of rotor punching groove groove is 22.6mm.

The utility model changes the diel of rotor punching, goes out the rotor punching body with the 50WW470 cold-reduced silicon sheet on punch press, does not change original assembling mode of motor; It is the rotor core of the 180-4 utmost point that this punching is used for high efficiency motor center height, can improve the efficient of motor, and in use procedure for a long time, electromagnetic noise is little, starting current is little, and torque is large.
