Energy Saving in Motor Start-up

Energy Saving in Compressor's Motor Start-up

Potential Energy Saving in Speed Controlled Compressor


What is Speed Control?

These Compressors are usually Direct Coupled, Direct Drive, meaning the Main Motor is directly driving the Rotor [usually Male Rotor].

Is a Electronically based control, where the speed [rpm] of Main Drive Motor is varied to adjust the free air delivery [FAD] to change in Plant air usage.

* If Demand Increase!
Motor Speed is increased, and therefore, the speed of the rotors is increased -----> free air delivery increases.

* If Demand Decrease!
Motor Speed is reduced, and therefore, the speed of the rotors is reduced -----> free air delivery decreases.
