Abstract
The unity model relates to a fan-shaped impulse tablets alternate current motor stator iron core, in particular to a stator iron core of the alternate current motor. The unity model solves the current problem of the lug appearing and deformation of the fan-shaped alternate current motor stator iron core. The fan-shaped impulse alternate current motor stator iron core includes the fan-shaped impulse tablets forming stator iron core, the groove on one side of the fan-shaped impulse tablets, and the convex on other side of the fan-shaped impulse tablets, the groove and convex connecting together when rowing the round. The model adopts connecting the fan-shaped impulse tablets stator iron core construction, forming a whole part by its coupling between the constructions of the fan-shaped impulse tablets, and preventing the appearing of the lug and deformation. The stress on the drawing screw rod should be smaller than the former one, and the deformation influence will be controlled in a certain range, which ensured the motor security and reliable running. The stated fan-shaped impulse tablets alternate current motor stator iorn core construction is designed reasonably and easily, and can be used reliably and safely.
Description
Technical field
The utility model relates to alternating current machine, and particularly the stator core of alternating current machine (comprising synchronous motor, asynchronous machine) is specially the stator core of a kind of segmental punching alternating current machine.
Background technology
Stator core is the critical component of alternating current machine, is the path of alternating current machine rotating magnetic field.At present, segmental punching is adopted in the large ac machines stator core mostly, and every punching has two standing screw holes on the outside, and punching is stacked in draws on the screw rod, compress by trim ring, then by nut tightly welding.But in running,, add the weight of punching itself and the influence of vibration simultaneously because the influence of magnetic flux draws screw rod to generate heat, lug easily takes place in stator core, just indivedual fanning strips protrude in iron core, scratch stator winding insulation when serious, cause the short fault of motor ground connection or circle.Simultaneously, the long-term rotating operation of motor because magnetic flux, the weight of punching itself and the influence of vibration draw screw rod to have amount of deflection, thereby causes distortion unshakable in one's determination.Generally, solve problem on deformation drawing welding of screw rod middle part or mounting plate, but complex process, the reliability requirement height.It is particularly outstanding that lug unshakable in one's determination and metaboly show on large ac machines.
Summary of the invention
The utility model provides the stator core of a kind of improved segmental punching alternating current machine in order to solve the problem that lug and metaboly easily take place in existing segmental punching alternating current machine stator core.
The utility model is to adopt following technical scheme to realize: the stator core of segmental punching alternating current machine, comprise the segmental punching that builds up stator core, one side of segmental punching has groove, and opposite side is provided with double wedge, and row's bowlder segmental punching splicing lateral raised teeth and groove fasten mutually.Adopt to fasten (coupling) segmental punching stator core structure mutually, be coupled each other, form an integral body, prevented the generation of lug and metaboly by segmental punching.Draw stress on the screw rod also less than original structure simultaneously, the influence of distortion is controlled in certain scope, has guaranteed motor safety, reliability service.
Segmental punching alternating current machine stator core structure described in the utility model is reasonable in design, simple, safe and reliable.

Fig. 2 is segmental punching and row's circle structural representation;
1-draws screw rod among the figure; The 2-nut; The 3-trim ring; The 4-support; The 5-stator core; The fan-shaped notch punching of 6-; The fan-shaped end plate of 7-; The 8-segmental punching; The 9-groove; The 10-double wedge; 11-standing screw hole.
Embodiment
The stator core of segmental punching alternating current machine comprises the segmental punching 8 that builds up stator core 5, and a side of segmental punching has groove 9, and opposite side is provided with double wedge 10, and row's bowlder segmental punching splicing lateral raised teeth and groove fasten mutually.It is a full circle that 12 fanning strips are adopted in stator core 5, with existing unshakable in one's determination the same, has two standing screw holes 11 on every punching outside, and segmental punching is stacked on the baffle plate that draws screw rod 1 and support 4, and full circle is pieced together on support.Compressed by trim ring 3, two ends are tight by 2 on nut then, nut and trim ring spot welding again.The two ends of stator core also are respectively equipped with fan-shaped notch punching 6 and fan-shaped end plate 7.
Mutual coupling fanning strip stator core structure first Application directly drives in the rig in exchanging, and important technological parameters is as follows:
Type: asynchronous motor stator iron core
Number of poles: 24
Number of stator slots: 144
Stator core is long: 500mm
Frame diameter: 1450mm
Frame bore: 1270mm
