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 ...

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 ...

Here are two simple 12V DC motor speed controllers that can be built for just a few dollars. Here are two simple 12V DC motor speed controllers that can be built for just a few dollars. They exploit ...

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.

Why a two-speed transmission when 10-speeds are readily available? Electric motors have a vastly broader "sweet spot" of efficient torque delivery than combustion engines, so they don't need frequent ...

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, ...

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 ...

This file type includes high resolution graphics and schematics when applicable. Today’s machine-tool shops need high speeds and high torques to quickly and efficiently carve complex parts out of ...
