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 ...

When powering AC motors, the electrical supply can be at full power to run at full speed or at variable power to run at variable speed. Applications with varying loads benefit from the variable speed ...

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 ...

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 ...
