Abstract
The utility model discloses a stator punched sheet for a motor. A plurality of winding grooves (2) are uniformly distributed in the stator punched sheet (1), wherein the width of the open end A of each winding groove (2) is less than the width of the bottom of the winding groove (2); and 12 winding grooves (2) are uniformly distributed in the stator punched sheet (1), wherein the winding grooves (2) are U-shaped, and the width of the opening of each U-shaped winding groove (2) is less than the width of the bottom of the winding groove (2). With the adoption of the structure that the plurality of winding grooves are uniformly distributed in the stator punched sheet, and the width of the open end of each winding groove is less than the width of the bottom of the winding groove, the stator punched sheet for the motor disclosed by the utility model is low in cost, high in efficiency, and capable of remarkably improving the performance of the motor so that lampblack exhaust is more efficient, energy-saving, and easy to adjust the speed. The utility model discloses a stator punched sheet for a motor, which is ingenious in design, excellent in performance, convenient and practical.
Description
Technical field
The utility model is a kind of stator punching of motor, and particularly a kind of stator punching that is used for the brush DC fume exhauster motor belongs to the renovation technique of the stator punching of motor.
Background technology
The shortcoming that the stator punching of the existing used motor of most of smoke exhaust ventilator on the market exists is that the punching size is big, and the groove number is many, and winding construction adopts the distributed winding structural shape mostly, makes that motor enamelled wire consumption is big, the motor cost height; And motor performance is low, temperature rise, noise height.
Summary of the invention
The purpose of this utility model is to consider the problems referred to above and stator punching that a kind of low cost, high efficiency motor are provided.The utility model can significantly improve motor properties, makes more efficient, energy-conservation, the easy speed governing of smoke exhaust ventilator.
The technical solution of the utility model is: the stator punching of motor of the present utility model, be evenly equipped with some winding slots on the stator punching, and wherein the width of the openend A of winding slot is littler than the bottom width of winding slot.
Be evenly equipped with 12 winding slots in the said stator punching, winding slot is the U type, and the A/F of U type is littler than the bottom width of winding slot.
In addition, be evenly equipped with 24 auxiliary tanks on the inner periphery of said stator punching.
The utility model is evenly equipped with some winding slots owing to adopting on the stator punching, the structure that the width of the openend of winding slot is littler than the bottom width of winding slot, and therefore, the utility model becomes to hang down originally, the efficient height.In addition, be evenly equipped with 24 auxiliary tanks on the inner periphery of said stator punching.Auxiliary tank can reduce cogging torque, improves the noise of motor properties and reduction motor.The utility model can significantly improve motor properties, makes more efficient, energy-conservation, the easy speed governing of smoke pumping.The utility model is that a kind of design is ingenious, function admirable, the stator punching of convenient and practical motor.
