Description

Technical Field

[0001] This utility model relates to the field of electric motor equipment technology, and more specifically, to an electric motor with a multi-seal structure. Background Technology

[0002] An electric motor is a device that converts electrical energy into mechanical energy. It uses an energized coil to generate a rotating magnetic field, which acts on the rotor to form a magnetoelectric torque. The motor housing is usually composed of multiple parts, such as the connection between the end cover and the base. To prevent external substances from entering the motor through these connection gaps, sealing bolts with sealing washers are used at the connection bolts.

[0003] In environments with high salt spray and high humidity, these harsh conditions continuously erode the sealing structure of the motor casing, accelerating the aging of the sealing materials and leading to seal failure. This, in turn, damages the internal structure of the motor and affects its service life. Utility Model Content
