Abstract

The invention relates to the field of hub motor sealing and discloses an end face sealing structure for the motor and the stator of a hub motor. The end face sealing structure comprises a rotor, a stator and a sealing member disposed between the rotor and the stator, wherein the sealing member comprises a mounting portion and a sealing lip; a support skeleton is arranged inside or outside the mounting portion; the sealing lip is in seal fit with the end face of the rotor or the stator; the sealing member can be installed with the rotor and the stator in two ways in one of which the mounting portion is mounted on the rotor and the sealing lip is in sealed against the end face of the stator and in the other of which the mounting portion is mounted on the stator and the sealing lip is in sealed against with the end face of the rotor. The solution in the present invention is designed for solving the technical problem that the conventional hub motor has no reliable sealing member between the stator and the rotor. The sealing member designed by the invention is a separate component, is liable to form and prone to standardized production so as to be convenient in later maintenance.
