Abstract
The utility model provides a rotor punching sheet of a motor and belongs to the electromechanical technical field. With the rotor punching sheet of the motor of the utility model adopted, the problem of unreasonable structure of a rotor punching sheet of a motor in the prior art can be solved. The rotor punching sheet of the motor of the utility model includes a round punching sheet body. A shaft hole is arranged at the middle of the punching sheet body. The side wall of the shaft hole is provided with key grooves. 60 magnet grooves are uniformly arranged the outer peripheral part of the punching sheet body; 12 circular through holes are uniformly arranged at the inner peripheral part of the punching sheet body; and a plurality of V-shaped grooves are arranged between the magnet grooves and the through holes. The rotor punching sheet of the motor of the utility model is advantageous in reasonable structure.
Description
Technical field
The utility model belongs to the mechanical ﹠ electrical technology field, has related to a kind of rotor punching of motor.
Background technology
Along with constantly advancing of society, improving constantly of scientific and technological level, the development of electromechanics trade, the market demand can constantly change, the new extension and connotation of motor product is also constantly expanded, and motor product is supporting wide, and it is widely used in the every field such as the energy, traffic, oil, chemical industry, metallurgy, mine, building, and the versatility of motor is progressively to specificity aspect development, broken the situation that same class motor in the past is used for heterogeneity, different occasions simultaneously.
Reduce in the whole world under the background of energy consumption, energy-saving efficient motor becomes the common recognition of global motor industry development.
Stator punching is the key components and parts of generator, and its material, inner circle size, excircle dimension, flute profile size etc. have direct impact to the energy-saving efficiency of generator.And the generator that uses in the market, the energy-saving efficiency of its stator punching is lower, and above-mentioned reason is the unreasonable structure of stator punching.
Summary of the invention
The utility model is for the problems referred to above that prior art exists, and proposed a kind of rotor punching of motor rational in infrastructure.
The utility model is realized by following technical proposal: a kind of rotor punching of motor, comprise circular punching body, the middle part of described punching body has axis hole, the sidewall of this axis hole has keyway, it is characterized in that, the peripheral part of described punching body is equipped with 60 magnet steel grooves, and the interior perimembranous of described punching body is equipped with 12 manholes, also has several V-shaped grooves between described magnet steel groove and the described through hole.
In the rotor punching of above-mentioned a kind of motor, the outside of described magnet steel groove has a kerf.
In the rotor punching of above-mentioned a kind of motor, the cross sectional shape of described magnet steel groove is notch cuttype.
Compared with prior art, the rotor punching of this motor has advantages of rational in infrastructure.
