The line of adjustable-speed drives provide accurate and repeatable speed settings and can be used as a prime mover connected to a motor, or as a secondary drive The line of adjustable-speed drives ...

Prior to the advent of the adjustable-speed drive (ASD), the polyphase induction motor operated as a constant-speed motor. Figure 1 shows the well-known torque and current curves versus speed for the ...

Imagine an easy-to-install industrial technology that reduces energy consumption, eliminates mechanical vibrations and electronic harmonics, relaxes alignment tolerances and cuts maintenance needs.

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 ...

SIEMENS is introducing a new high-performance drive to the North American market. Sinamics G220 is a multi-purpose adjustable speed drive with built-in “clean power” technology, which reduces ...

Article 430, Part X provides the NEC requirements for adjustable-speed drive systems. Notice the word “systems,” which means this covers more than the drive itself. Size the branch or feeder circuit ...

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 ...

It is interesting to look at figures from the Energy Information Administration about where energy gets consumed in our economy. These figures reveal that industrial uses account for 31% of all energy ...

Adjustable speed drive allows easy adjustment of application rates — for example, for seed and fertilizer distribution. Accurate, repeatable speed settings; when used as a prime mover, drive acts as a ...

Sinamics G220 is a multi-purpose adjustable speed drive with built-in clean power technology, which reduces harmonics by up to 97% without the need for an AC line reactor or DC choke. Sinamics G220 is ...
