Abstract
The utility model relates to a motor stator punching. The stator punching (1) is formed by connecting eight blocks (2) having identical size and shape together in a buckling manner. Each block (2) is provided with a male part (3) and a female part (4) having a self-locking function on the left and the right. The manufacturing quality of the stator punching in the utility model is easier to be guaranteed. The material cost and manufacturing cost are lowered substantially, and no environment pollution is made in the production process. A motor adopting the motor stator punching provided in the utility model can save more electricity and have higher efficiency. And the service lifetime of the motor can be prolonged.
Description
Technical field
The utility model is a kind of motor stator punching, and particularly a kind of piecemeal composite type ventilation fan motor stator punching that is used for ventilation fan belongs to the renovation technique of motor stator punching.
Background technology
Existing used in air exchange fan capacitor motor adopts traditional stator structure all the time mostly, and there is the problem of following 6 aspects in it: 1) traditional capacitor motor stator structure is difficult to avoid inter-turn insulation to take place; 2) traditional capacitor motor stator structure is winding the line, the line of fall, and colligation, integer is difficult in the processes such as dipping lacquer guarantee that really the magnet wire insulation paint film is injury-free; 3) traditional capacitor motor stator structure is being difficult to aspect material cost and the manufacturing cost that breakthrough is arranged again, even stint no sacrifice quality replaces copper cash as using copper-clad aluminum conductor, cold drawing replaces silicon steel plate etc., and effect is also not obvious; 4) traditional capacitor motor stator structure must carry out the dipping lacquer processing, and is bad to environment; 5) for the manufacturing of traditional capacitor motor stator, because jet-bedding paper, the line of fall, wiring, integer, operations such as dipping lacquer necessarily need a large amount of staff, become and hardly may so reduce direct labor's quantity; 5) therefore traditional capacitor motor stator winding structure pursues more power saving of motor, more efficient being restricted because line of fall process technology limit can't overcome winding overhang loss problem.
Summary of the invention
The purpose of this utility model is to consider the problems referred to above and provides a kind of quality bills of materials easier guarantee, the motor stator punching that material cost and manufacturing cost are improved significantly.Production process of the present utility model is free from environmental pollution, and the motor made from the utility model is power saving and efficient operation more more, and can prolong motor useful life.
The technical solution of the utility model is: a kind of motor stator punching is characterized in that stator punching is formed by 8 sizes and the identical piecemeal fastening of shape, is provided with the convex portion and the concave portion of band self-clinching function about each piecemeal.
It is 2.29～3mm that raised part is divided the evagination height H.
Above-mentioned concave portion indent degree of depth h is 3～3.01mm.
The inner diameter d of said stator punching is 37～41mm.
The outer diameter D of said stator punching is 71～75mm.
Slot opening B after above-mentioned piecemeal fastens is 0.7～0.9mm.
The utility model is owing to adopt piecemeal buckle-type ventilation fan motor stator structure to replace traditional type capacitor motor stator structure, after the utility model is used for ventilation fan, compare with traditional type capacitor motor stator structure, has following effect: 1) because adopt coiling framework winding, can accomplish that winding displacement is even, winding high voltage position portion does not end to end contact, main paying alternately do not contact, thereby stop the possibility that inter-turn insulation takes place, make the electrical machine insulation life-span longer, motor uses more reliable, and motor market is complained minimizing and stopped; 2) directly coiling, sectional type coiling back combination, the no line of fall and dipping lacquer operation.It is bad fundamentally to stop production process generation turn-to-turn, thereby reduces defective products; 3) compare with traditional capacitor motor stator structure, owing to well solved the winding overhang problem, the enamelled wire consumption can significantly reduce, the also corresponding raising of motor performance, and simultaneously owing to the no line of fall, no dipping lacquer operation, cost of labor and manufacturing cost also significantly reduce; 4) because need not dipping lacquer handles, good to environment; 5) owing to do not need to carry out the jet-bedding paper of conventional motors, the line of fall, wiring, integer, operations such as dipping lacquer, the needed direct labor's quantity of whole stator production process reduce to original about 1/3,6) power saving and efficient----are because directly adopt the centralized efficient winding of 1/2 pitch, finely overcome winding overhang loss problem, so the more power saving of utility model motor, more efficient.
