Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a wire embedding structure of a switched reluctance motor. Background Art

[0002] Compared with traditional motors, switched reluctance motors have the advantages of simple structure, small size, and high power density.

[0009] Preferably, the threads at both ends of the threaded rod have opposite rotation directions.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] When the utility model is in use, the elastic limiting ring is pulled upwards to rotate the rotating block, and the rotating block drives the second bevel gear to rotate through the connecting rod, so that the first bevel gear drives the threaded rod to rotate, and the slider drives the winding molds to move away from or approach each other, so that the distance between the winding molds can be adjusted, so as to be suitable for the winding operation of coils of different lengths. The elastic limiting ring is pressed down so that the corner of the rotating block is stuck in the limiting groove, so as to limit the rotating block, and prevent the connecting rod from driving the second bevel gear and the first bevel gear to rotate, and complete the winding of the coil on the winding mold, and then the wound coil is sleeved on the salient pole of the stator core, thereby improving the wire embedding efficiency.
