The invention belongs to the technical field of electrical and mechanical transmission, and discloses a hub motor stator cooling structure, a hub motor stator and a hub motor, the hub motor stator cooling structure comprises a cooling fin module, the end face of the cooling fin module is provided with a cooling medium inlet and a cooling medium outlet, and the cooling fin module is internally provided with a flow channel communicated with the inlet and outlet; the cooling fin modules are arranged at the two ends of the stator core to form a new stator core structure, and the stator winding is wound on stator teeth on the inner side of the stator core structure. And the contact surface of the radiating fin module and the end part of the stator winding is a smooth arc curved surface. Good thermal contact is achieved between the cooling fin module and the stator winding and the insulating layer, heat caused by motor winding copper loss and stator iron loss can be rapidly taken away, the cooling capacity of the hub motor stator is effectively improved, and the temperature rise of the motor stator is remarkably reduced. The heat radiation fin module enhances the heat radiation capability of the end part of the winding on the premise of ensuring higher slot space factor of the motor and not damaging the original structure of the motor stator.
