Abstract
The utility model provides a rotor punching sheet of a generator, which belongs to the field of dynamo-electric technology. The punching sheet solves the problem that the structure of the rotor punching sheet of the generator in the prior art is unreasonable. The rotor punching sheet of a generator comprises a circular punching sheet body, the central section of the punching sheet body has a shaft hole, the side wall of the shaft hole is provided with key slots, the periphery of the punching sheet body is uniformly provided with 34 closed magnetic steel grooves, through holes are arranged between the magnetic steel grooves and the shaft hole along the circumference of the shaft hole, and each through hole has a trapezoid-shaped cross section. The rotor punching sheet is advantageous by reasonable structure.
Description
Technical field
The utility model belongs to mechanical & electrical technology field, has related to a kind of rotor punching of generator.
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 same class motor in the past simultaneously for the situation of heterogeneity, different occasions.
In the whole world, reduce 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 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 using 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, for the problems referred to above of prior art existence, has proposed a kind of rotor punching of generator rational in infrastructure.
The utility model is realized by following technical proposal: a kind of rotor punching of generator, comprise circular punching body, the middle part of described punching body has axis hole, the sidewall of described axis hole has keyway, it is characterized in that, the peripheral part of described punching body is equipped with the magnet steel groove of 34 closos, has the through hole circumferentially arranging along axis hole between described magnet steel groove and described axis hole, and the cross section of described through hole is trapezoidal.
In the rotor punching of above-mentioned a kind of generator, the cross sectional shape of described magnet steel groove is " protruding " font.
In the rotor punching of above-mentioned a kind of generator, the quantity of described through hole is 18.
Compared with prior art, the rotor punching of this generator has advantages of rational in infrastructure, has improved the energy-saving efficiency of generator while being applied on generator.
Accompanying drawing explanation
Fig. 1 is the structural representation of the rotor punching of this generator.
In figure, 1, punching body; 2, magnet steel groove; 3, axis hole; 4, keyway; 5, through hole.
Embodiment
Be below 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 generator, comprise circular punching body 1, the middle part of punching body 1 has axis hole 3, and the sidewall of axis hole 3 has keyway 4, and the peripheral part of punching body 1 is equipped with the magnet steel groove 2 of 34 closos, the cross sectional shape of magnet steel groove 2 is " protruding " font, between magnet steel groove 2 and axis hole 3, have the through hole 4 circumferentially arranging along axis hole 3, the cross section of through hole 4 is trapezoidal, and the quantity of through hole is 18.
Specific embodiment described herein is only 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 supplements 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.
