Abstract
The utility model provides a motor rotor punching sheet and belongs to electromechanical technical field. The utility model resolves a problem of unreasonable structure of a motor rotor punching sheet in the prior art. The motor rotor punching sheet comprises a circular punching sheet body. A shaft hole is disposed on the center of the punching sheet body. Three keyways are uniformly disposed on the circumferential wall of the shaft hole. The punching sheet body is equally divided along the radial direction into an inner circumferential portion close to the shaft hole side and an outer circumferential portion outside the inner circumferential portion. Three heat-dissipating holes are uniformly disposed on the inner circumferential portion. Five magnetic steel slots are disposed on the outer circumferential portion. The motor rotor punching sheet has an advantage of 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
The effect of motor is to produce driving torque, as the power source of electrical equipment or various machineries, is widely used in the fields such as industry, agricultural, business, building industry.
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 efficient of motor.And use in the market the motor of more YGT and Z2 series, its rotor punching can't reach the purpose that improves electric efficiency, and in use realize also to have the defectives such as electromagnetic noise is large, starting current is large, 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, and when this rotor punching is used on motor, motor has advantages of that electromagnetic noise is little, starting current is little.
The utility model is realized by following technical proposal: a kind of rotor punching of motor, comprise circular punching body, described punching body middle part has axis hole, it is characterized in that, described axis hole perisporium is equipped with 3 keyways, described punching body radially is divided near the interior perimembranous of axis hole side and is positioned at the outer peripheral part of perimembranous, is evenly equipped with 3 louvres on described interior perimembranous, is provided with 5 magnet steel grooves on described peripheral part.
In the rotor punching of above-mentioned a kind of motor, the outside of described magnet steel groove has opening.
In the rotor punching of above-mentioned a kind of motor, the shape of described louvre is curved.
Compared with prior art, the rotor punching of this motor has advantages of rational in infrastructure, when this rotor punching is applied on motor, can reduce the electromagnetic noise of motor and the advantage of starting current.
Description of drawings
Fig. 1 is the structural representation of the rotor punching of this motor.
In figure, 1, the punching body; 2, axis hole; 3, keyway; 4, peripheral part; 5, magnet steel groove; 6, interior perimembranous; 7. louvre; 8, opening.
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 motor, comprise circular punching body 1, the middle part of punching body 1 has axis hole 2, axis hole 2 perisporiums are equipped with 3 keyways 5, punching body 1 radially is divided near the interior perimembranous 6 of axis hole 2 sides and is positioned at the outer peripheral part 4 of perimembranous 6, is evenly equipped with 3 louvres 7 on interior perimembranous 6, and the shape of louvre 7 is curved; Be provided with 5 magnet steel grooves 5 on peripheral part 4, the outside of magnet steel groove 5 has opening 8.
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 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.
