MOTOR CONTROL CIRCUIT FOR LEVEL LASER

摘要

A motor control circuit for a level laser comprises a motor speed adjustment module and a speed stabilization module, wherein the speed stabilization module comprises a single-chip microcomputer and a motor speed stabilization chip, the single-chip microcomputer controls the motor speed stabilization chip, and the motor speed stabilization chip is connected to two ends of a motor. The motor speed adjustment module comprises a resistance adjustable device, and the rotational speed of the motor may be adjusted by changing the resistance value of the resistance adjustable device. The control circuit improves the use efficiency of the single-chip microcomputer.
