How do brains turn environmental inputs into motor outputs? This question, known as the “black box” problem, has left ...

In Part 1 of this two-part series, we presented a 3-phase, 480VAC motor circuit with its associated controls (Figure). We stepped through a logical, systematic approach to troubleshoot the main power ...

Single-phase and 3-phase AC squirrel cage induction motors need some type of control circuit to initiate a start or stop function. The two types of ladder control circuits commonly used are the 2-wire ...

Here is a motor speed sensor module, the major goal is to check the rate of an electric motor. The module can be used in association with a microcontroller for motor speed detection, pulse count, ...

Microcontrollers may dominate today’s stepper motor projects, but there’s a charm in driving them with pure CMOS logic. Try ...

Using a multi-shunt-based current-monitoring circuit with a 50-MHz op amp delivers an overcurrent detection response time of ...

This circuit automatically turns a motor cycle’s headlight on and off, independently of both the light and ignition switches, provided the battery is fully charged. The first stage uses the 22O ...

Father of Lotus, Colin Chapman, said his secret to engineering racing and sports cars was to "add lightness." An intriguing phrase, to say the least. And one that might well have been lost in time by ...
