Abstract
The utility model relates to a draw-bar type stator iron core structure for a double-feed asynchronous wind-power generator. The draw-bar type stator iron core structure comprises stator pressing rings, stator punching sheets, stator end plates, ventilation groove steel, a draw bar, a fixed seat, nuts, a stator iron core, a plurality of circular holes and a plurality of semicircular holes. The semicircular holes are arranged at outer edges of the stator punching sheets and the stator end plates. The circular holes are reserved on the stator pressing rings, the ventilation groove steel is mounted on the stator end plates, the stator pressing rings, the stator punching sheets and the stator end plates penetrate through the draw bar and are stacked and locked by the nuts. The fixed seat is welded on the outer circumference of the stator iron core. In the draw-bar type stator iron core structure, a motor punching sheet is utilized reasonably, a motor is small in size, light in weight, simple in structure, free of welding, convenient to operate, and fine in motor ventilation and heat radiation effect, and production cost is reduced.
Description
Technical field: the utility model relates to a kind of dual-feed asynchronous wind power generator and uses the rod-pulling type stator core structure.
Background technology: cylindrical welding rectangular steel plates form is adopted in traditional dual-feed asynchronous wind power generator stator core; This form is at surface attachment reinforcement unshakable in one's determination, need weld at reinforcement and engagement edge unshakable in one's determination, and the volume that reinforcement occupies radial space is big; The waste of rear of core volume; Under the condition that guarantees the adequate ventilation area, increased the overall volume of motor, increased weight, the waste production cost.
Summary of the invention: the purpose of the utility model is to overcome above-mentioned shortcoming; Provide a kind of dual-feed asynchronous wind power generator to use the rod-pulling type stator core structure; It has mainly solved the traditional structure stator core and has adopted cylindrical welding rectangular steel plates form; At surface attachment reinforcement unshakable in one's determination, the volume that occupies radial space is big, problems such as rear of core volume waste.The purpose of the utility model is achieved in that a kind of dual-feed asynchronous wind power generator is made up of: stator pressing ring, stator punching, stator end plate, ventilation channel-section steel, pull bar, holder, nut, stator core, circular hole, semicircle orifice with the rod-pulling type stator core structure.The outer edge of stator punching and stator end plate is provided with a plurality of semicircle orifices; Stator pressing ring is provided with a plurality of circular holes, and the ventilation channel-section steel is installed on the stator end plate, and stator pressing ring, stator punching, stator end plate pass pull bar and laminate; And use nut check, holder to be welded on the cylindrical of stator core.This product adopts the rod-pulling type stator core structure, rationally utilizes motor stamping, and motor volume little 10,000 is in light weight, simple in structure, need not welding, and easy to operate, the motor ventilation good heat dissipation effect has reduced production cost.
