Intelligent control application of motor

Abstract

The invention relates to an intelligent control application of a motor. The intelligent control application comprises a single-chip microcomputer, a driver, a pressure sensor, the motor and a pump head; the driver and the pressure sensor are both electrically connected with the single-chip microcomputer under weak current; the motor is electrically connected with the driver; the pump head is in drive connection with the motor; the pressure sensor is in sensing connection with the pump head. The driver is externally connected with a first conducting wire carrying high current. The motor is externally connected with a second conducting wire carrying high current. The driver and the motor are connected with a third conducting wire carrying high current. The intelligent control application has the advantages that control of weak current control signals is achieved through mechanical-loss-free electronic devices and the high-power motor, service lives of electric products can be greatly prolonged, the problem that traditionally excess current directly carried by a sensor or a control switch causes damage or shortened life to the sensor or the control switch is solved, no carbon accumulation occurs during long-term running, and running 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. (Column: 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 ef...

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.
