DC Motor Clockwise Anticlockwise Control H-bridge Circuit
This circuit can control the direction of a DC motor, allowing it to operate in both clockwise and counterclockwise directions (forward and backward).
The described circuit employs an H-bridge configuration, which is essential for reversing the polarity of the voltage applied...
DC Motor-Driver H-Bridge Circuit
A very popular circuit for driving DC motors (ordinary or gearhead) is called an H-bridge. It's called that because it looks like the capital letter 'H' on classic schematics. The great ability of an H-bridge circuit is that the motor...
PWM Motor Speed Control Using Class D Audio Amplifier
This is a Class D audio amplifier circuit used to control the PWM motor speed. This circuit has two advantages for battery-powered portable devices. First, it provides high efficiency, which extends battery life.
The Class D audio amplifier operates by modulating...
PWM Motor Speed Controller
A pulse width modulator (PWM) is a device that may be used as an efficient light dimmer or DC motor speed controller. The circuit described here is for a general purpose device that can control DC devices which draw up...
Driving Stepper
M1 is a stepper taken from an old disk drive. There are five pins, i.e., common, coil 1, 2, 3 and 4. Resistance measured between common pin and each coil is about 75 Ohms. Driving current for each coil is...
