Energy-saving controller of three-phase asynchronous motor

Abstract

The invention discloses an energy-saving controller of a three-phase asynchronous motor. The energy-saving controller comprises a housing, cooling fins, a cooling water tank and an integrated controller. The three-phase asynchronous motor is fixedly arranged in the housing; and cooling fins are fixedly installed on the inner wall of the housing. Each cooling fin comprises a contact piece, a fin body and a heat dissipation pipeline. The heat dissipation pipelines between the two groups of cooling fins are communicated through a first pipeline. The cooling water tank is fixedly arranged in the housing. The heat dissipation pipelines on the two groups of cooling fins are communicated with the cooling water tank through second pipelines; miniature water pumps are arranged on the group of second pipelines; a plurality of groups of semiconductor chilling plates are installed on the side face, corresponding to the rear portion of the housing, of the cooling water tank in an embedded mode; anintegrated controller is installed on the housing in an embedded mode; and the integrated controller comprises an integrated installation housing and a single-chip microcomputer installed in the integrated installation housing. The invention has the advantages of preventing high temperature from weakening the working effect of the motor and prolonging the service life of the motor.

Description

technical field [0001] The invention relates to the technical field of motor energy saving, in particular to a three-phase asynchronous motor energy saving controller. Background technique [0002] With the continuous development of our society, the industrial strength is gradually increasing. The motor in industrial production is an indispensable electrical equipment, and most of the motors in industrial production work for a long time and at high frequency. After working for a long time, the motor itself A large amount of heat will be generated. The higher the temperature, the greater the DC resistance of the winding of the stator or rotor. At the same current, the loss will be greater. It will affect the permanent magnet inside the motor, cause the permanent magnet to demagnetize, and cause damage to the motor. Contents of the invention [0003] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide an energy-sa...
