Let us begin this session by revisiting a nostalgic motor control IC—the AN6651—designed for rotating speed control of compact DC motors used in tape recorders, record players, and similar devices.

Sophisticated motor control is no longer the sole province of custom hardware and proprietary control techniques. Advances in powerful, low-cost digital-signal controllers (DSCs) let designers use ...

1. How is back EMF generated? The generation of back electromotive force is easy to understand. The principle is that the conductor cuts the magnetic lines of force. As long as there is relative ...

High-speed solenoid valves and electromagnetic actuators represent a critical intersection of electrical and mechanical engineering, enabling rapid, precise control of fluid or gas flows in a myriad ...

A brushless-DC motor is common in ceiling fan and pan-tilt-zoom (PTZ) camera designs. But you can’t use the same brushless-DC motor solution for both of these end products. A ceiling fan driver ...
