Abstract

The invention belongs to the field of circuit control, and provides a control circuit and device. According to the control circuit, after interference signals in city alternating currents are filtered out through a rectifying and filtering module, the city alternating currents are converted into direct currents, more stable current signals are provided for a motor, working currents of the motor are further stabilized through a constant-current control module, so that the working currents of the motor are more stable, working voltage of the motor is prevented from being too high through an overvoltage protection module, and accordingly, the motor is prevented from being damaged. The control circuit can stabilize the city alternating currents and provide stable currents for the motor, design is simple, meanwhile, the reliability of the control circuit itself is guaranteed, and the design cost is also lowered.

Description

technical field [0001] The invention belongs to the field of circuit control, in particular to a control circuit and a device. Background technique [0002] Since the discovery and application of electricity, it has played an irreplaceable role in the rapid development of society. The motor is a product that emerged with the development of electricity. It plays an indispensable role in the production and life of people. Greatly promoted the development of human society. [0003] However, the current motor is unstable due to the instability of the mains itself and the complex design of the control circuit, and its control circuit is complex and costly. When the current is large, it is easy to cause damage to the motor and reduce the service life of the motor. . Contents of the invention [0004] The object of the present invention is to provide a control circuit aimed at solving the problems of complicated design, poor stability and high cost of the existing motor control...
