variable frequency drivesIn recognizing the potential of connectivity, and motor and system independence, Danfoss Drives give customers the freedom to optimize their systems, and the power to equip their drives to ensure they engineer the best possible AC-drive solutions without compromises and find the optimum outcome for their challenges.

7 Reasons for using Variable Frequency Drives

Variable frequency Drives vary the frequency and voltage of the power supply and are vital for controlling the ramp-up and ramp-down of the motor during the start or stop phases. Controlling the frequency and voltage is also referred to as speed control, because the result of this process is an adjustment in motor speed.

Use a VFD to:

  • Save energy and improve system efficiency.
  • Convert power in hybridization applications.
  • Match the speed of the drive to the process requirements.
  • Match the torque or power of a drive to the process requirements.
  • Improve the working environment.
  • Lower noise levels, for example from fans and pumps.
  • Reduce mechanical stress on machines to extend their lifetime.
    Shave peak consumption to avoid peak-demand prices and reduce the motor size required.

VFD Case Study

Take a closer look at how VFD’s dramatically reduce energy consumption in this Crowne Plaza hotel

‘’Designed for sustainability, Crowne Plaza Copenhagen Towers is truly engineering tomorrow, with 60% lower electricity consumption than comparable hotels operating conventional energy technology, in 2015. Deploying the best environmental and energy technology, the hotel comes close to achieving carbon neutrality.’’

ACS Variable Frequency Drives

The most common uses of a VFD are for control of fans, pumps and compressors, and these applications account for 75% of all drives operating globally.
