Abstract
The utility model relates to a punching sheet for induction motors in rotary drum washing machines. The punching sheet comprises a stator punching sheet (1) and a rotor punching sheet (2), wherein the middle portion of the stator punching sheet (1) is provided with a hollow inner circular hole (11), the rotor punching sheet (2) is arranged in the hollow inner circular hole (11) of the stator punching sheet, the inner circular edge of the stator punching sheet (1) is provided with a plurality of stator punching sheet grooves (12) along the circumference direction, and the outer circular edge of the rotor punching sheet (2) is provided with a plurality of rotor punching sheet grooves (21) along the circumference direction. The punching sheet is characterized in that the appearance dimension of the stator punching sheet A is equal to 106-108 mm, and B is equal to 106-108 mm, the stator punching sheet grooves (12) are circular-bottom grooves, and 33-35 rotor punching sheet grooves (21) are provided. Compared with the prior art, the punching sheet has the beneficial effects that the number of the rotor punching sheet grooves is increased, the number of electrified conductors in a magnetic field is more when the motor works, the output torque of a motor is enlarged, the starting time of the motor is shortened, the working current is reduced, therefore, the temperature of the motor is reduced, since the stator punching grooves are changed into the circular-bottom grooves, the yoke magnetic density of a stator is reduced, the appearance dimension of the punching sheet is relatively reduced, thereby using few silicon steel sheets, and reducing the cost of the motor.
Description
Technical field
The utility model is a kind of punching of rotary drum washing machine class induction machine, belongs to the improvement technology of rotary drum washing machine class induction machine punching.
Background technology
The punching structure of existing rotary drum washing machine class induction machine as shown in Figure 1, comprise stator punching 1 and rotor punching 2, the overall dimension A=108-110mm of stator punching, B=108-110mm, circular hole 11 in the hollow has been made at the middle part of stator punching 1, along the circumferential direction be provided with several stator punching grooves 12 on the internal circle of stator punching 1, stator punching groove 12 is a dovetail groove, along the circumferential direction be provided with 30 rotor punching grooves 21 on the outer circumferential edge of rotor punching 2, rotor punching 2 places in the interior circular hole 11 of stator punching hollow, there is following shortcoming in the punching of the rotary drum washing machine class induction machine of said structure: because the rotor punching groove is less relatively, be that electrical conductor number in the magnetic field is less relatively, so motor output torque is relatively low, low output torque, cause the electric motor starting time longer relatively, operating current is relatively large, makes electric machine temperature rise higher; 2, stator punching is selected dovetail groove for use, causes stator yoke portion magnetic close higher relatively, and close for reducing yoke portion magnetic, the overall dimension A of stator punching and B will make as above-mentioned size, and the silicon steel sheet consumption is more, and motor cost is higher relatively.
The utility model content
The purpose of this utility model is to consider the problems referred to above and a kind of low temperature rise is provided, big torque, the punching of rotary drum washing machine class induction machine cheaply.
The technical solution of the utility model is: a kind of punching of rotary drum washing machine class induction machine, comprise stator punching and rotor punching, circular hole in the hollow has been made at the middle part of stator punching, rotor punching places in the interior circular hole of stator punching hollow, along the circumferential direction be provided with several stator punching grooves on the internal circle of stator punching, along the circumferential direction be provided with several rotor punching grooves on the outer circumferential edge of rotor punching, overall dimension A=106～the 108mm that it is characterized in that described stator punching, B=106～108mm, the stator punching groove is a round bottomed vessel, and the rotor punching groove is 33～35.
The utility model has following beneficial effect compared with prior art:
One, the utility model rotor punching groove number increases, and during machine operation, the electrical conductor number in the magnetic field is many, and motor output torque increases, and the starting time of motor shortens, and operating current reduces, and therefore, the temperature rise of motor is minimized;
Two, the utility model stator punching groove is used round bottomed vessel instead, and the yoke portion magnetic that has reduced stator is close, makes that stator punching overall dimension is corresponding to be reduced, and therefore, the silicon steel sheet consumption is few, and motor cost is low
