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 Speed ...

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 is the first part exploring the motor control shield that I designed for the project where I was doing 3D Printer Filament Measuring with Arduino. The DC motor portion of the project is based on ...

The 555 timer IC is a handful of active components all baked into one beautifully useful 8 pin package. Originally designed for timing purposes, they became ubiquitous parts that can achieve almost ...

DC motors are used extensively in industrial variable speed applications because of most demanding speed-torque characteristics and are simple in controlling aspects. This paper presents a DC motor ...

To successfully integrate the drive into the system, the controller must provide full functionality for motor control. The more functions the drive itself can implement, the fewer add-ons and ...

The circuit in this Idea for Design provides three levels of speed control for a dc motor using a PC’s parallel port (LPT1). A C++ program performs the control functions by allowing the signals from ...

Related to my search for reduced motor noise (and thanks to all who have made suggestions – ‘scope avaunt this weekend), is a search for speed stability in that motor*. And to someone who is in love ...
