Embodiment Construction

[0018] A wound-type motor with a new rotor lead wire fixing structure, including a shaft 5 with a shaft hole, a rotor coil 1, and a rotor lead wire 4 welded on the rotor coil 1. A fastening ring 2 is arranged on the shaft 5 to fasten A beveled waist-shaped wire groove is processed on the ring 2, and the rotor lead-out wire 4 passes through the fastening ring 2 and the waist-shaped groove, and then penetrates into the hole of the rotating shaft, and the lead-out wire is fixed on the fastening ring 2 with the clip 3, and the rotating shaft The hole is filled with gel 6, and the rotor lead wire 4 is fixed in the hole of the rotating shaft through heating and curing.

[0019] The fastening ring 2 is made of non-magnetic material, and is connected with the rotating shaft 5 through an interference fit. The fastening ring 2 is processed with oblique waist-shaped wire grooves, and the rotor lead-out wire 4 passes through the shaft hole. It will automatically fit into the waist groove....

Abstract

The invention relates to a winding motor, in particular to a rotor leading-out wire of the winding motor, more particularly to a winding motor with a novel rotor leading-out wire fixing structure, which solves the problem that the traditional winding asynchronous motor has poor reliability of the leading-out wire, easy grounding of a shaft and the leading-out wire and turn-to-turn short circuit caused by the deformation of the leading-out wire. The winding motor comprises a rotating shaft, a rotor winding and a rotor leading-out wire welded on the rotor winding, wherein a fastening ring is arranged on the rotating shaft, the rotor leading-out wire penetrates out of a rotating shaft hole after passing through the fastening ring and is fixed on the fastening ring by using a clamp, gel is filled in the rotating shaft hole, and the rotor leading-out wire is fixed in the rotating shaft hole through heating and curing. By adopting the invention, the problem of fixing failure of the rotor leading-out wire can be solved, the defect of the grounding of the rotor leading-out wire is overcome, and the insulation failure grounding of the rotor leading-out wire, which is caused by local overheating because of eddy current loss, is avoided.

Description

technical field [0001] The invention relates to a wound-type motor, in particular to a rotor lead-out wire of a wound-type motor, in particular to a wound-type motor with a novel rotor lead-out fixing structure. Background technique [0002] In the prior art, for the fixing structure of the rotor lead-out wires of small-sized wound asynchronous motors, the lead-out wire slots are generally processed on the surface of the rotating shaft, and then the rotor lead-out wires are directly bound and fixed on the rotating shaft. Because the diameter of the lead-out wire is small, it is not greatly affected by the centrifugal force, and this method can be used to achieve the reliable fixing of the lead-out wire. However, the high-power wound asynchronous motor is subjected to a large centrifugal force due to the thicker wire diameter of the lead-out wire. The lead-out wire of the rotor usually adopts a wire-pressing seat structure to press the lead-out wire on the shaft. This structu...
