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 ...

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 ...

Traditional 12V to 48V motor drive systems typically use an MCU paired with three separate gate drivers. However, rising demand for higher efficiency and more precise control is accelerating the shift ...

A dc motor driving an ac alternator was used to simulate an asynchronous wind electric generator. The output was used to drive a commercial air conditioning unit containing a hermetically sealed three ...

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) ...

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 ...

For the PDF version of this article, including diagrams, click here. Laptop/notebook PC cooling fans demand low noise and high efficiency. The latter is particularly important as notebook designers ...

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 ...

Lincoln Electric and Edge Energy are bringing DC fast charging with speeds of up to 100 kW to sites WITHOUT 3-phase power.
