You can salvage some nice motors out of optical drives but they can be tricky to control. That’s because brushless DC motors require carefully timed signals used in a process called Electronic ...

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 ...

Approx circuit of DC-51 motor speed controller (D6 and D8 are the wrong way around, and there may be more errors). And the more I looked at the circuit, the more I liked the speed controller. Update ...

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.

The load allowed the DC-51 motor speed controller current limit preset to be adjusted. As the control was working right down one end (max is 4A and the motor max is 0.9A), and is very light in action ...

Maxon Precision Motor's ESCON 50/5 OEM module is a 4 quadrant Pulse Width Modulated (PWM) servo motor controller that can efficiently control permanent magnet brushed DC ...

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.

Until end of January 2015, both the RGB Lighting Shield with XMC1202 for Arduino and the DC Motor Control Shield with BTN8982TA for Arduino, are available for purchase from Farnell element14 and ...
