MOTOR AND INDUSTRIAL ROBOT

Embodiments of the present disclosure relate to a motor and an industrial robot. The motor comprises a main body, an inner end cover, an outer end cover, a first oil seal, a second oil seal and an oil leakage sensor. The main body comprises a rotor extending along an axial direction. The inner end cover is coupled to the main body and comprises a first hole for the rotor to pass through. The outer end cover is arranged outside the inner end cover along the axial direction and abuts against the inner end cover. The outer end cover comprises a second hole for the rotor to pass through, wherein a first oil seal is arranged adjacent to the second hole and a second oil seal is arranged inside the first oil seal and is adjacent to the second hole. A gap is provided between the first oil seal and the second oil seal along the axial direction. The oil leakage sensor is provided in a through hole penetrating the outer end cover along the axial direction and is configured to detect the amount of oil or grease flowing to the oil leakage sensor via the first oil seal. The motor according to the present disclosure is characterized in dual sealing and an automatic oil leakage detection, thereby improving the motor sealing reliability and the digitalization of the motor oil leakage detection.
