When you get the call, “The motor won’t start,” you’d best have a logical and systematic plan in place to approach the problem. “Easter egging” just doesn’t work unless you happen to be very lucky!

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 ...

Electric motors consume almost half of the electricity produced worldwide. They, in fact, provide the necessary driving force for much of today’s equipment. Motors, pumps, and fans are present in an ...

Altech’s load-safe LSF Series and RT Series non-fusible motor disconnect switches and accessories de-energize electrical circuits for safe maintenance, repairs, inspections and emergencies. RS has ...

Embedded exhibition sets out to simplify DC motor control circuits Richard Wilson Simplifying the design of DC motor control circuits was the aim of a number of microcontroller announcements at last ...

As with internal-combustion vehicles, the advantages of all-wheel drive for electric vehicles have been obvious from the start as has been the potential to provide multiple motors, ideally one for ...

To make something work using electricity there needs to be an electrical circuit; a circuit is a complete loop that electricity can move around. Electricity moves from the power source (the battery or ...
