Available for the CFW-11 variable-speed drive, the Pump Genius process control software manages and monitors up to six pumps in a coordinated system. It can operate motors from 5-150 hp in the 208- ...

Variable-speed drives are a powerful yet underused tool for boosting energy efficiency, reducing emissions, and optimizing ...

The Ultratech™ variable-speed motor is a four-wire electronically commutated motor with two-way communication. The motor receives commands from the furnace system control board, executes the command, ...

It is this variable output that is used to control motor speed, torque, or position. PWM is used in modern adjustable frequency drives because it is efficient.

This paper presents a DC motor speed controlling technique under varying load condition. The linear system model of separately excited DC motor with Torque-variation is designed using PID controller.
