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 ...

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 ...

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 ...

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) ...

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 ...

Matching drive to motor is essential to gain the best combination of torque, speed, and efficiency. Selecting the right drive is essential to getting the best performance and efficiency from an ...
