Few hackers have trouble understanding basic electric motors. We’ve all taken apart something that has a permanent magnet DC motor in it and hooked up its two leads to a battery to make it spin.

The project utilizes scavenged stepper motors from disk drives or printers with some probing of an ohmmeter followed by some simple driver code on the microprocessor. The project utilizes scavenged ...

Illustrated in this project is the use of stepper motors in order to generate electricity that may be used to power LEDs, charge some batteries or even drive a motor. Illustrated in this project is ...

Brushless-dc motors are taking center stage in medical-equipment design because they last twice as long a competing technologies. • Sensorless brushless-dc-drives have evolved to a point where they ...

The International Electrotechnical Commission (IEC) defines a servo device as “an adjustable-speed AC power drive system that includes an AC motor integrated by feedback, a converter, and control, ...
