Abstract
An example includes a housing, a stator assembly, a rotor, and a self-cooling structure. The stator assembly is mounted on the housing and fitted around the rotor, the rotor is rotatably housed within the housing, the self-cooling structure is attached to the rotor, and the self-cooling structure is located at the stator assembly. The self-cooling structure comprises an outer cylinder, an inner cylinder, and a plurality of blades, wherein the plurality of blades are radially connected between the inner cylinder and the outer cylinder. A ventilation slot is formed between the outer cylinder and the inner cylinder, with multiple end-face air intake holes formed at the ventilation slot, and side exhaust holes are formed between adjacent two blades, with the end-face air intake holes being in communication with the side exhaust holes. In this way, it is capable of actively dissipating heat within the motor without altering its form.
