A miniature permanent magnet generator inner stator winding embedding tool

Abstract

The invention discloses an embedding tool for a stator winding in a micro permanent magnet generator. The tool consists of an I-shaped winding board, a combined fixture, a combined cushion block, a shaft-including fixed base and a movable handle. The tool is structurally characterized in that the I-shaped winding board can be fixed between upper and lower clamping plates by adjusting a butterfly-shaped nut on the combined fixture; a left cushion block of the combined cushion block sleeves a shaft of the shaft-including fixed base, and sleeves a right cushion block of the combined cushion block on which the stator core in the micro permanent magnet generator is arranged; the movable handle is arranged on a thread at the tail end of the shaft of the shaft-including fixed base, and is rotated clockwise till the combined cushion is clamped tightly by the movable handle. The embedding tool has the advantages that the entire set of tool is low in cost, and is easy to machine. By using the embedding tool together with a pedal type winding machine, the transition of the conventional embedding process for the stator winding in the micro permanent magnet generator from a pure manual operation mode to a semi-automatic +manual operation mode can be realized, one person can finish all embedding procedures, the embedding time is effectively shortened, and the embedding quality is ensured.

Description

technical field [0001] The invention relates to a new type of tool, in particular to an embedded tool for stator windings in a miniature permanent magnet generator. Background technique [0002] The inner stator winding of the miniature permanent magnet generator belongs to the soft winding. The traditional embedding process is manual operation. Two people work in a group. One person supports the inner stator core placed on the iron frame to prevent the iron core from falling over, and the other person directly puts the inner stator core on the iron frame. The enameled wire is embedded into the inner stator slot of the generator, and the enameled wire is tightened by hand every time it is inserted. Restricted by the ductility of the enameled wire, the traditional manual embedding cannot smoothly embed the windings evenly and tightly in the inner stator slot, and the quality of the embedding cannot be guaranteed. It takes time to arrange the copper wires in the slot many time...

Problems solved by technology

Restricted by the ductility of the enameled wire, the traditional manual embedding cannot smoothly embed the windings evenly and tightly in the inner stator slot, and the quality of the embedding cannot be guaranteed. It takes time to arrange the copper wires in the slot many times, which is inefficient and high in production costs.
