Energy savings

Parker Hannifin has launched a new family of AC drives that allow energy efficient permanent magnet motors to be used in a wide range of pump, fan and compressor applications.

The AC650S Series eliminates the need to run permanent magnet motors with closed loop speed sensors, enabling them to be used as replacements for induction motors.

The company says that using the AC650S drives to switch from induction to permanent magnet motors can cut energy consumption by up to 12% while reducing the combined drive and motor envelope by up to 75%. The new drives provide high start-up torque without the need for additional tuning.
