Description

Technical Field

[0001] The utility model relates to the technical field of motors, and more particularly, to a wire pay-off device. Background Art

[0002] When repairing a mining flameproof three-phase asynchronous motor, it is necessary to wind an enameled wire winding. Currently, the mainly used enameled wire is round enameled wire winding, and when winding, it is necessary to pay off the enameled wire with an "I-shaped" structure; among them, the round enameled wire winding refers to a single enameled layer 120-grade enameled copper round wire based on polyvinyl acetal resin.

[0003] Although the current wire pay-off form can realize the smooth winding of the coil, due to the limitations of its own structure, the following problems exist in the coil winding process:

[0004] (1) The coil winding relies on the winding machine to pull the "I-shaped" wire reel to rotate. When the weight of the wire reel is large, the friction between the wire reel and the steel pipe increases, and the winding tension also increases accordingly. When the enameled wire bears too much tension, the wire diameter of the enameled wire will become thinner, thus affecting the repair quality of the stator winding;

[0005] (2) When the winding machine stops winding, since the wire pay-off device has no braking device, the wire reel will continue to rotate under the action of inertia and finally brake by its own friction, which easily leads to loose and disordered wires on the wire reel;

[0006] (3) Multiple wire reels are threaded on a steel pipe, which is not convenient for replacing the wire reel and poses a safety hazard. Content of the Utility Model
