Brushed motor speed control device

INTRODUCTION

When operating commutator electric motors, it is often necessary to regulate the speed of the device. At the same time, it is important not to reduce the overall performance of the motor so that the work does not go down the drain. 

Power units of this type are actively used in household electrical appliances, tools: washing machines, grinders, vacuum cleaners, drills, quadcopters, etc. This is due to the high performance of devices that demonstrate a large number of revolutions and high torque (also starting). These technical characteristics are more than enough to ensure the operation of equipment and tools at the required level. 

The motors themselves operate from both direct and alternating current networks, from ordinary household networks. To control the speed of the rotor of such an engine, it is necessary to use special regulators. At the same time, power losses will be minimal. 

In this course project, devices for controlling the speed of rotation of a commutator motor under the control of a microcontroller are developed. The task of the device is also to adjust the speed of rotation of the brushed motor.
