Title:
MOTOR STRUCTURE, MOTOR AND CLEANING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/124716
Kind Code:
A1
Abstract:
Disclosed in the present application are a motor structure, a motor and a cleaning apparatus. The motor structure comprises a casing, a stator assembly and a rotor assembly, the stator assembly and the rotor assembly being arranged in the casing. The stator assembly sleeves the rotor assembly. A heat dissipation space is formed between one end of the stator assembly and the inner wall of the casing, a heat conduction piece being arranged in the heat dissipation space. The motor structure in the present application solves the problem that because heat generated by a stator winding of a motor cannot be dissipated in time, the temperature rise of the motor is excessively high and accordingly the motor cannot work normally or even fails.
