Abstract

The invention discloses a motor control circuit, a motor control system and a motor driving device. The motor control circuit comprises a first control unit and a second control unit, the first control unit and the second control unit are used for controlling a motor to rotate forwards or reversely, and the second control unit is further used for controlling the rotating speed of the motor. One end of the first control unit is connected with a power supply, the other end of the first control unit is connected with the motor, one end of the second control unit is connected with the motor, and the other end of the second control unit is grounded; or one end of the second control unit is connected with the power supply, the other end of the second control unit is connected with the motor, one end of the first control unit is connected with the motor, and the other end of the first control unit is grounded. The motor control circuit can realize positive and negative rotation control and rotating speed control of the motor, the control mode is simple, convenient and practical, and miniaturization design of products is facilitated.

Description

technical field [0001] The invention relates to the technical field of motor control, in particular to a motor control circuit, a motor control system, and a motor drive device. Background technique [0002] With the increasing maturity of motor manufacturing technology, more and more motors with simple operation, convenient control and diversified functions are used in various industries, and the design of motor drive circuits has also received extensive attention. In the related art, the motor can only complete the forward and reverse functions, and the motor often controls the steering of the motor by changing the hardware circuit, which results in a large volume of the motor and is inconvenient to use. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. [0004] Therefore, the first object of the present invention is to provide a motor control circuit to realize the forwa...
