This microcontroller-based control circuit adjusts the speed of a small permanent-magnet DC motor to one of four speeds as selected by a pair of photosensors.

The DC motor speed control project is intended to manage the pace of a DC motor by means of an 8051 sequence micro-controller. The pace of DC motor is straightforwardly relative to the voltage ...

This paper presents a DC motor speed controlling technique under varying load condition. The linear system model of separately excited DC motor with Torque-variation is designed using PID controller.

He hooks up the SN754410 to two motors, giving him speed and direction control for both based on the duty cycle of a PWM signal entering the chip for less than $2.50.

As a result of the efforts of Smart Motor Devices engineers, a cost-effective, full-featured and reliable controller BMD-20DIN ver.2 for DC brush motors is available now at the industrial market.

These highly integrated, 8-bit MCUs are optimized for cost-sensitive motor control applications. The new C8051F85x/6x MCUs combine analog and communications peripherals, flash sizes ranging from 2 kB ...

En route to getting the off-the-peg DC-51 motor speed controller to better suit my small milling machine, I had a go at working out what the circuit is.

Speed Control of Motors Speed, torque, and horsepower are three inter-related parameters in motor control. The speed of a motor, measured in revolutions per minute (rpm), defines a motor's ability to ...

This 8051 microcontroller-based control circuit adjusts the speed of a small permanent-magnet dc motor via photosensors (see the figure). The circuit can find applications in light-tracking ...
