Variable-pitch drives are the simplest of all mechanical adjustable-speed mechanisms.

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 ...

Variable mechanical drives are less costly than competing electrical variable-speed drives and their control is much simpler.

It's easy to understand how variable-speed motor drives benefit pumps and blowers from the energy curves that depict their performance.

Drive and motor manufacturers can also help to improve the power factor with variable speed drives. VSDs help solve the power factor problem, while improving process control, saving electrical energy, ...

A variable speed drive (VSD) controls the speed of the high-torque, direct-drive motor for optimal fan operation.

The MagnaDrive Adjustable Speed Drive (ASD) is based on the principles of standard AC eddy current variable speed drives but does not need an AC motor to create the electromagnetic fields. The ...

Voith introduces the first member of a new product family in the field of speed control for compressors and pumps: the VECO-Drive.

Drive and motor manufacturers can also help to improve the power factor with variable speed drives. VSDs help solve the power factor problem, while improving process control, saving electrical ...
