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 ...

Permanent magnet dc motors need a chunky inductor in series with them if they are fed from an SCR (thyristor) based mains power controller. It is (probably!) possible to safely interface an Arduino to ...

RS, a high-service global product and service solutions provider for industrial customers, offers Schneider Electric's ...

You use limit switches to switch off a motor if it reaches one of its two end positions. Even if you build a microprocessor-based motor controller, you should switch off a motor with hardware by ...

Read part 1 of this series on construction and operating principles here. Having understood the construction and basic operating principle of BLDC motor in the first part of this article, it becomes ...

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 spin at a rate per unit ...

I have been trying to fix a little old milling machine I bought (and here), and needed a replacement motor controller. It is a Clarke DCM10, a variant of Sieg’s X1, sometimes knows as a ‘micro mill’.
