Abstract
The utility model provides a rotor sheet of an electric motor and belongs to the field of electromechanical technology. The rotor sheet of the electric motor overcomes an inappropriate structure of a rotor sheet of an electric motor in the prior art. The rotor sheet of the electric motor provided by the utility model comprises a circular rotor sheet body, a circular axle hole is arranged in the middle part of the rotor sheet body, and a key groove is arranged in the side wall of the axle hole. The rotor sheet of the electric motor is characterized in that: 56 magnet steel grooves are distributed in an external part of the rotor sheet body in a circumferential direction; a plurality of separately arranged rectangular holes are arranged between the magnet steel grooves and the axle hole; and the plurality of the rectangular holes are connected together to form a star on the rotor sheet body. The rotor sheet of the electric motor is advantaged by a proper 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.
Rotor punching is the key components and parts of motor, and its material, inner circle size, excircle dimension, flute profile size etc. have direct impact to the energy-saving efficiency of motor.And the motor that uses in the market, the energy-saving efficiency of its rotor punching is lower, and above-mentioned reason is the unreasonable structure of rotor 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 circular axis hole, the sidewall of described axis hole has keyway, it is characterized in that, the exterior circumferential of described punching body is distributed with 56 magnet steel grooves, has the rectangular opening that several minutes are arranged between described magnet steel groove and the described axis hole, and several described rectangular openings are linked to be together described punching body formation one star.
In the rotor punching of above-mentioned motor, the quantity of described rectangular opening is 8.
Compared with prior art, the rotor punching of this motor has advantage rational in infrastructure.
Description of drawings
Fig. 1 is the structural representation of the rotor punching of this motor.
Among the figure, 1, the punching body; 2, magnet steel groove; 3, rectangular opening; 4, axis hole; 5, keyway.
Embodiment
Below be specific embodiment of the utility model, and by reference to the accompanying drawings the technical solution of the utility model be further described, but the utility model is not limited to these embodiment.
As shown in Figure 1, a kind of rotor punching of motor, comprise circular punching body 1, the middle part of punching body 1 has circular axis hole 4, the sidewall of axis hole 4 has keyway 5, the exterior circumferential of punching body 1 is distributed with 56 magnet steel grooves 2, has the rectangular opening 3 that several minutes are arranged between magnet steel groove 2 and the axis hole 4, and several rectangular openings 3 are linked to be together punching body 1 formation one star.In the present embodiment, the quantity of rectangular opening is 8.
Specific embodiment described herein only is to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
