Many applications using miniature brushed DC motors require motors to operate at more than one load point or through specific load cycles. Running a motor at usable load points requires a variable ...

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 ...

In designing a simple spectroscopy setup, we needed to synchronize the speed of a small, inexpensive dc motor precisely to 6000 rpm (100 Hz). Our first idea was to take a phase-frequency detector type ...

Recently, I found an interesting fan motor module in a web shop and grabbed a couple of them for nothing. At the heart of the module is an eight-pin L9110 DC motor control chip from ASIC (www.asic.net ...

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 Electroni… ...

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.

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 ...

Pulse-width modulated motor drives are becoming the dominant method of variable speed motor control, and are being used not only in industry, but in applications as diverse as electric vehicles and ...
