More Information
Summary:The invention relates to the manufacture field of motors, and discloses a structure realizing a radial axis of a high power motor and a welding process. The radial axis structure of the motor comprises a rotor shaft (1) and a support rod (2), wherein the support rod (2) is installed between the rotor shaft (1) and a rotor sheet (4) of the motor, and the rotor shaft (1) and the support rod (2) are welded into a radial structure. The rotor shaft (1) of the motor adopts No.45 steel or 40Cr, and the support rod (2) adopts Q235-A carbon steel. The invention has the beneficial effects of saving materials, being favorable for heat radiation of the rotor surface and rotor cage bars, increasing the welded structure of the Q235-A radial rod by adopting the 40Cr axis, ensuring that the rotor axis does not have cracks after conditioning by applying the new process and measures, having very good welding effect, ensuring the performance of the motor, and adapting to the market requirements.
