A kind of intelligent control application of electric motor

Abstract

The intelligent control application of a kind of electric motor of the present invention, comprises single-chip microcomputer, and the driver and the pressure sensor that are connected with single-chip microcomputer respectively weakly, and the motor that is electrically connected with driver, and the pump head that is connected with motor drive, and described pump head The sensor is connected to a pressure sensor; the driver is externally connected with a high-current load wire; the motor is externally connected with a high-current load wire, and the driver is connected to the motor with a high-current load wire. The invention realizes the control signal of the micro-current to control the high-power motor load of the electronic device without mechanical loss, which can greatly prolong the service life of the electrical product, and solve the problem of excessive load current directly controlled by the sensor or control switch in the past. The control switch is damaged or the life is shortened. Long-term work will not produce carbon deposition, which is safe and reliable.

Description

technical field [0001] The invention relates to an intelligent control application of a motor. Background technique [0002] In the existing motor control method, when the motor needs to be intelligently controlled, the load current of the motor flows directly through the control switch, or is completed through the conversion of the relay. However, the working principle of the control switch and the relay is contact conduction, and long-term work will cause carbon deposition and damage after excessive temperature. If the load current is too large, the life of the control switch and the relay will be greatly reduced. (Example: 3-month or 6-month warranty for water pump motor merchants on the market) cannot meet the national quality life standard. The speed of the motor is directly related to the frequency, and the speed of the motor will decrease when the frequency is low, so that the mechanical efficiency driven by the motor will decrease, and it will also affect the use e...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a control signal of a micro-current to control a high-power motor load through an electronic device without mechanical loss, which can greatly prolong the service life of the electrical product and solve the problem caused by sensors or control switches in the past. The current load is too large and the negative effect of the voltage rising edge generated at the moment of power-on will cause damage to the sensor or control switch or shorten the life. Long-term work will not produce carbon deposits. It is a safe and reliable intelligent control application for motors.
