One of the hidden complications of upgrading grain drying and handling systems is providing enough electricity to power the new larger electric motors. Electric motors that are larger than 15 hp ...

Home machinists can often find great deals on used industrial equipment, and many a South Bend lathe or Bridgeport milling machine has followed someone home. Then comes the moment to plug it in, and ...

It’s impossible to balance line-to-line voltages perfectly in three-phase circuits, so they typically differ by a few volts or more. However, if voltage unbalance exceeds 1%, it can markedly decrease ...

There are several reasons to use a three-phase inverter to run a single-phase induction motor, including isolation from variable power grids, reduction of peak currents and elimination of the starting ...

This application note presents the vector control of a 3-phase AC induction motor using the Z8FMC16100 microcontrollers. This document also briefly describes the series of Z8FMC16100 flash ...

What You’ll Learn: The origins of Permanent Magnet Brushless DC motors (PMDC). How the efficiency of electric motors increases as you increase the number of phases. How to optimally control stators as ...

In the original version of this article, the second figure contained an error. The image has been updated. It’s important for engineers to have a good, working ...

One of the more popular three-phase electrical services supplied to medium-size commercial buildings is the Wye or Star configuration transformer. The name comes from the transformer’s secondary ...
