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 ...

Rolling-ring drives are friction drives that convert the constant rotary motion of a plain shaft into a traversing action that moves an attached carriage. Used in positioning and reciprocating ...

“Variable speed compressors and drives act similarly to a car’s accelerator pedal, which enables the driver to control and match the speed of the car to their exact needs at any given moment or road ...

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 ...

As a hybrid technology that combines mechanical and electrical systems, electrohydraulic variable speed drives allow for motor speed adjustments to conserve energy and provide precise control over ...
