Motors can be wired delta or wye. Which arrangement do you choose, and how do you do it? For purposes of making the connection, it doesn’t matter to the installer if the motor is delta-wound or ...

In power distribution systems, three-phase transformer configuration directly impacts system reliability and load management.

So you just spent three hours removing and replacing a motor that drives the feed to a robotic welder. You connected the leads exactly the way they were before you disconnected them. You properly ...

A motor control IC is a convenient way to implement custom motor drive algorithms such as the single-phase induction motor (SPIM) control. A generalized control algorithm, implemented and tested in an ...

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 ...

The flux-oriented control (FOC) is a commonly used technique for three-phase electric motor control application. Here, the applied voltage pattern is defined using the space vector modulation (SVM) ...

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 ...

This solid-state thyristor (SCR) switch circuit is perhaps the simplest means of reversing a 3 phase motor. “Static” is a catch-all term that essentially means without moving (mechanical) contacts ...

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 ...
