Electromotor device with heat dissipating and noise reducing functions

Abstract

The invention discloses an electromotor device with heat dissipating and noise reducing functions. The electromotor device comprises a base and an electromotor, wherein the base is provided with the electromotor, the electromotor is provided with a power interface, a rotating shaft is arranged at one side of the electromotor, a spline is arranged on the rotating shaft, turbine cooling fins are arranged at the other side of the electromotor, liquid coolant is arranged at the center of the turbo cooling fins, heat sink strips are arranged at one side of the turbine cooling fins, a noise reduction box is arranged outside the electromotor. The electromotor device with heat dissipating and noise reducing functions is simple in structure, low in manufacturing cost and high in practicability; through an eddy formed by the turbine cooling fins, a circular airflow is formed inside the electromotor; by virtue of the liquid coolant on the turbines, the temperature of the electromotor can be reduced; due to use of the heat sink strips, the temperature can be reduced more rapidly and conveniently; therefore, the double cooling effect is achieved; since the noise reduction box is arranged outside the electromotor, noise can be reduced and the electromotor can be prevented from being affected by the outside.

Description

technical field [0001] The invention relates to a motor device, in particular to a motor device for heat dissipation and noise reduction. 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 direction). The working p...

[0003] The motor shell is an important part of the motor, which plays the role of positioning and protection. However, the existing motor shell is prone to generate a lot of heat after working for a long time, and sometimes it will explode due to thermal expansion, which will affect the work of the motor.

At the same time, when the motor is working, it is easy to generate noise, the working environment is not good, and it is easy to affect the lives of nearby residents, which brings troubles to people. This phenomenon is caused by the inability to accurately know the temperature of the motor and cannot control it, causing the motor to be overheated. explode
