A single-speed motor has one rated speed at which it runs when supplied with the nameplate voltage and frequency. A multispeed motor will run at more than one speed depending on how you connect it to ...

The Stumpex auger-type stump grinder now includes a 2-Speed hydraulic motor for faster stump removal, especially on soft woods. The grinder improves cut time by up to 50 percent, the company says, ...

PSC motors rely on the rotating magnetic field that is generated by the applied alternating voltage and corresponding alternating current to turn the rotor. The magnetic field rotates at 3,600 rpm (60 ...

Full-voltage, single-speed motor starters: Single-speed squirrel-cage motors have starters that fall into two categories: full-voltage or across-the-line starters; and reduced-voltage starters.

As part of its asset management strategy, Nucor Steel replaces two-speed motors with variable frequency drives to reduce energy and water use as well as maintenance costs. With all the focus on energy ...

Even though many EV aficionados are not really on-board with the idea of putting a gearbox in an electric car, it looks like manufacturers are still doing it. Right now only the Porsche Taycan and ...

A synchronous and synchronous motors are the two main categories of ac motors. The induction motor is a common form of asynchronous motor and is basically an ac transformer with a rotating secondary.

Pretty much all mainstream electric cars integrate their electric motors with single-speed, often 10:1-ish gear reductions, mostly because it's cheap and easy, and it works. But now, the German ...

New layout for a 2-speed might be light and compact while maintaining efficiency Could potentially allow strong launch with a lower-cost motor unit Idea might be due in future Lucid EVs, or engineers ...

When it came time to confront the chore of keeping our 1960 Corvette project’s windshield clean during inclement weather, we quickly came up with four valid reasons to replace the factory system with ...
