Cooling and protection device for motor

Abstract

The invention discloses a cooling and protection device for a motor, which comprises a motor and a protection cover sleeving the surface of the motor shell, wherein the shell surface of the motor is provided with first connection plates; the shell surface of the motor is vertically symmetrically provided with grooves; the rear end of the protection cover is connected with a cooling fan mounting seat; the rear end of the cooling fan mounting seat is provided with a cooling cover; the cooling fan mounting seat is internally fixed with a fan through supporting rods; and the inner side of the protection cover is provided with shock-absorbing sleeves clamped in the grooves. Due to a spring and the arrangement of the lower end of the spring being located inside the shock-absorbing sleeve, when shock is generated when the motor works, the spring plays a shock-absorbing role, and the motor can be effectively prevented from transferring the shock to the protection cover. Through operation of the fan, heat generated when the motor works can be exhausted through the cooling cover, a role of cooling the motor is played, the protection cover can completely protect the motor, and the motor is protected.

Description

technical field [0001] The invention relates to the technical field of electric motors, in particular to a heat dissipation protection device for electric motors. 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 field d...

AI Technical Summary

Problems solved by technology

[0003] The electric motor has a wide range of important applications in real life, and its place of use is relatively complicated. It is easy to cause inconvenient installation and fixation of the motor after being installed with the cooling device, and the cooling device often has a single function, which can only dissipate heat and cannot play a role in protecting the motor. At the same time, the connection between the cooling device and the motor is generally a fixed connection. When the motor is working, the vibration is directly transmitted to the cooling device, and the working noise is large.
