variable frequency drive motor Applications

  • Variable frequency drive controls AC motors

    Consider integrating a variable frequency drive. It often can optimize energy efficiency by enabling you to match motor speed to the demands of the system. Look for opportunities, for example, to replace throttle valves or dampers used to restrict flow. However, a variable frequency drive may not make sense if the load on the motor is relatively small and constant — because speed changes will occur infrequently and any benefits from varying the speed will be negligible. So, thoroughly assess the system load profile to determine the scale and frequency of required speed changes before deciding about installing a variable frequency drive.

  • Pumps and Wells

    Operational efficiencies make good sense for business and for resource preservation. To extend the life of wells, gain more production from them, and to safeguard expensive pumps and motors from running dry, companies are retrofitting well pumps with VFDs (Variable Frequency Drives). But even with VFDs, wells are not being optimized to produce the maximum sustainable amount of water and are still running dry resulting in damaging hard stops on pump motors.

    Drive-Chat powered remote access systems optimize well and irrigation operations. With it, it’s estimated that irrigation well production can be significantly increased.

    Drive‑Chat powered systems can:

    • Equalize pump and motor speed to maintain safe drawdown levels
    • Monitor well health
    • Eliminate dry holes and the potential for well collapse
    • Avoid pump damage due to emergency stops
    • Extend useful service life of the well
    • Receive real-time alerts before major failures occur
