Abstract

The invention relates to a protection device for a motor, and the motor. The motor comprises a motor end cover, which is arranged at the end portion of the motor, and is provided with a rotating shaftthrough hole used for penetrating through a motor rotating shaft and a plurality of ventilation openings formed around the rotating shaft through hole. The protection device can comprise a dustproofassembly arranged in a ventilation opening of a motor end cover so as to prevent dust of the motor, and / or a waterproof assembly connected with the motor end cover so as to carry out waterproof operation on a motor. According to the protection device for the motor, the ventilation opening is formed in the end cover, so that axial cooling of a heating element in the motor can be achieved so as to improve the heat dissipation effect; and the dustproof cotton is arranged in the end cover and the air inlet waterproof assembly is arranged in front of the end cover, so that dustproof and waterproofeffects can be effectively realized, manufacturing is simple and installation is convenient.

Description

technical field [0001] The present disclosure relates generally to the field of electric machine construction. More specifically, the present disclosure relates to a protection device for a motor and the motor. Background technique [0002] During the operation of the motor, the internal stator and rotor will generate a large amount of heat, which needs to be dissipated to the outside of the motor, so it is necessary to arrange air inlet and outlet for heat dissipation on some structures of the motor. [0003] However, foreign substances such as rainwater and dust may enter the inside of the motor from the air inlet and outlet, and these foreign substances will damage the internal parts of the motor and cause the motor to fail to operate. Therefore, there is a need to develop a protective device for the motor to improve the problem that foreign matter will enter the motor from the air inlet and outlet of the motor. Contents of the invention [0004] The purpose of the pr...
