2021年8月26日 · In this tutorial, we will cover the basic principles of DC motors and show you how to control the speed of a motor using PWM, an H-bridge circuit, and the L293D motor driver. A current carrying wire in the presence of a magnetic field experiences a mechanical force that acts in a particular direction.

2021年2月11日 · This page will show step by step the relationship between speed, torque and drive voltage of a DC motor, and how to control it.

2020年9月15日 · Here we will show how you can control a DC motor using the Arduino PWM build in capability. We will be using a general purpose transistor to amplify the output signal from the Arduino PWM pin. Also we will be using diode and decoupling capacitor for extra protection and reducing noise created by the DC motor.

In armature-controlled DC motors, the applied voltage Va controls the angular velocity w of the shaft. This example shows two DC motor control techniques for reducing the sensitivity of w to load variations (changes in the torque opposed by the motor load). A simplified model of the DC motor is shown above. The torque Td models load disturbances.

Thus, a variable-speed drive or VSD is a high-power circuit used to control the speed of a DC motor. Motor drives may be manually set to run a motor at a set speed, or accept an electronic control signal to vary the motor speed in the same manner an electronic signal commands a control valve to move.
