Description

Technical Field

[0002] The rotor winding refers to the winding installed on the rotor, that is, the copper wire wound on the rotor. The winding is a general term for a phase or the entire electromagnetic circuit composed of multiple coils or coil groups. Electric motors can be divided into centralized and distributed types according to the shape of the coil winding and the embedded wiring method. The rotor winding is generally equipped with specific tooling and can be customized according to different rotor winding requirements. During the rotor winding work, the disassembly and assembly of the rotor winding will directly affect the installation efficiency of the rotor winding;

The rotor winding tool provided by the utility model supports the rotor through the support shaft, and fixes the rotor by using the fixing frame, the first fixing component and the second fixing component. The rotor is restricted from moving along its axial direction during the winding process by the fixing frame and the second fixing component, so that the rotor can be wound; the rotor can be rotated by cooperating with the support shaft in rotation and removably fixing the rotor to the fixing frame by the second fixing component. Therefore, the above-mentioned rotor winding tool meets the rotor winding requirements;

[0004] The existing rotor winding die is directly installed on the winding rod gear. The inclined groove winding die is heavy and is directly subjected to force during winding, which reduces the service life of the bearing at the connection and causes the winding die to vibrate, affecting the wiring. For this reason, we propose a new rotor winding tooling to solve the above problems. Utility Model Content
