Motor cooling heat dissipation structure

The utility model relates to the technical field of heat dissipation structures, in particular to a motor cooling and heat dissipation structure, which comprises a motor body provided with a heat dissipation rear seat, and further comprises a heat dissipation processing part, a transmission assembly and a heat dissipation assembly, and the transmission assembly is used for driving the heat dissipation assembly to cool and dissipate heat through the motor body; the heat dissipation assembly comprises an outer mounting cover mounted at the heat dissipation rear seat, a heat dissipation fan is mounted in the outer mounting cover, and a heat dissipation outer cylinder is rotatably mounted outside the outer mounting cover; according to the motor cooling and heat dissipation structure, the heat dissipation assembly can be driven based on the output acting force of the motor through the transmission assembly, hot air can be discharged through a heat dissipation fan in the heat dissipation assembly for cooling, meanw
