Winding motor rotor lead support

The utility model relates to the technical field of motor heat dissipation devices, in particular to a winding motor rotor lead support which comprises a rotating shaft, a fan is fixedly connected tothe bottom of the rotating shaft, one fixing bearing is fixedly connected to the rotating shaft on the inner side of the connecting position of the fan and the rotating shaft, and the other fixing bearing is fixedly connected to the upper end of the rotating shaft. The two fixing bearings are symmetrically arranged relative to the center of the rotating shaft, vent holes are formed in the rotatingshaft, a rotor iron core is fixedly connected to the outer surface of the rotating shaft, heat dissipation holes are formed in the rotor iron core, penetrate through the rotor iron core and extend into the rotating shaft to be communicated with the vent holes, and winding grooves are formed in the outer surface of the rotor iron core. An electromagnetic winding is fixedly wound in the winding groove; the motor has the adv
