[Robert Murray-Smith] doesn’t like the price of inverters to convert DC to AC. That led him to build a dynamotor, or what is sometimes called a motor-generator set. These devices are just DC motors ...

Stepper motors are a subject that keeps recurring. This little circuit changes a clock signal (from a square wave generator) into signals with a 90-degree phase difference, which are required to drive ...

The MTD6501D is a three-phase full-wave driver designed for brushless sensorless DC motors. It has 180° sinusoidal drive, high torque output, and silent drive. It is intended to cover a wide range of ...
