Variable-stroke drives are most widely used in low-speed applications below 1.5 hp. They compete mainly with belt and chain drives and have running efficiencies near 80%. However, unlike belts, ...

For many retrofit projects, the use of a VFD seems like a “no brainer.” Drives are now cheaper and more reliable than ever, and the benefits of efficient control of motors can’t be beat. Still, there ...

The most reliable means for changing shaft speed remains a mechanical variable-speed transmission. These drives are used to provide a variable output speed from a constant-speed power source (as in a ...

In an industry evolving alongside consumer concerns over rising energy costs, impact on the environment, and, of course, stricter regulations handed down by the government, new technologies are ...
