A motor with a dust-proof and corrosion-resistant casing

Abstract

The invention provides a motor with a dustproof and anti-corrosion shell. The motor comprises a motor base and a plurality of heat dissipation plates arranged on the motor base. An exhaust mechanism is arranged on one side of the motor base. The motor further comprises a shell. Te shell is connected with the motor base through a heat dissipation plate. The shell has an open state and a closed state. When the shell is closed, a ventilation cavity is formed by the shell and the motor base. A filtering device is arranged at the end, away from the exhaust mechanism, of the ventilation cavity. Cooling fins are arranged on the motor base. The shell capable of being opened and closed is arranged on the cooling fins. When the shell is closed, the motor base is protected from being corroded. Meanwhile, the closed shell and the motor base form the ventilation cavity, so that the heat dissipation of the motor is not affected while the motor base is protected. When the shell is opened, the shell can extend as a heat dissipation plate. The heat dissipation area is increased, and the heat dissipation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of electric motors, in particular to an electric motor with a dust-proof and anti-corrosion shell. Background technique [0002] A motor is a device that converts electrical energy into mechanical energy. It uses energized coils (that is, stator windings) to generate a rotating magnetic field and acts on the rotor (such as a squirrel-cage closed aluminum frame) to form a magneto-electric power rotation torque. Motors are divided into DC motors and AC motors according to the power used. Most of the motors in the power system are AC motors, which can be synchronous motors or asynchronous motors (the motor stator magnetic field speed and rotor rotation speed do not maintain synchronous speed). The motor is mainly composed of a stator and a rotor. The direction of the current-carrying wire in the magnetic field is related to the direction of the current and the direction of the magnetic field line (magnetic fie...

AI Technical Summary

Problems solved by technology

The working principle of the motor is that the magnetic field acts on the force of the current to make the motor rotate; in the case of long-term operation or high-power operation, the internal temperature of the motor rises, and if the heat cannot be dissipated in time, the service life of the motor will be affected; When used in an environment where the motor is used, it is necessary to take anti-corrosion measures on the outer surface of the motor, such as adding a casing to the motor, but the addition of a casing to the motor will affect the heat dissipation of the motor
