Small DC Motor Speed Controller
Electric motor has been widely used as motion control, and many type of motor controllers have been designed to provide variable speed drives for the motor. The best controller is the servo controller, where a precise speed control is implemented using a speed sensor in the feedback path. The circuit of the motor controller in [...]

3 Phase AC Motor Speed Control
Controlling the speed of three phase ac motor is done by controlling the frequency of the power line supply, since the motor is synchronized with the line frequency. Three phase ac motor speed controller is actually nothing more than three phase sine wave power inverter with variable frequency. The three phase power inverter is a [...]

Analog Fan Speed Control
The large issue today that caused by more electronic equipment enters the home and the office is noise of fan. to reduce fan noise, a variable speed fan is used because it permits quieter and slower, fan speed when temperature conditions allow. To build a variable speed fan we can use digital control or high-speed/low-speed [...]

DC Motor Speed Control – Video Tutorial
This is a video tutorial of DC motor control. This video shows how to control the DC motor speed. In this video, speed of the DC motor is controlled by changing the power supply. Increasing speed can be done by increasing the voltage, and decreasing the voltage will decrease the speed of DC motor. Here [...]
