Variable Frequency Drives - Efficient Process Control

Variable frequency drives (VFDs) are electronic devices that control the speed and torque of motors in industrial, commercial, and residential applications. It is achieved by modulating the power frequency and voltage supplied to the motor.

VFDs provide more precise speed control compared to mechanical methods. By optimizing motor operation, VFDs improve process efficiency and energy savings.

VFD drives control fans, pumps, conveyors, mixers, and other motor-driven systems across many industries. 

 

Major VFD Drive Types and Applications

V/Hz (Volts per Hertz) VFDs:

  • The most basic and affordable type of VFD.
  • They control the motor speed by varying the voltage and frequency proportionally. So, the V/Hz ratio is kept constant.
  • No feedback on actual motor speed or torque. Open loop control.
  • Used mainly for simple applications where precise speed control is not critical. Examples are ventilation fans, conveyors, and pumps.
  • The low cost makes them popular for basic motor speed control needs.


Sensorless Vector VFDs:

  • More sophisticated drives that estimate motor speed and torque by measuring current and voltage.
  • This allows the drive to optimize voltage and frequency to provide better speed regulation and torque control than V/Hz drives.
  • It is well suited for applications like variable speed pumping, air handling, mixing, and conveying where good speed precision is needed.
  • It's more expensive than V/Hz drives but still relatively simple and affordable.


Closed Loop Vector VFDs:

  • Highest-performance VFDs use direct speed feedback from an encoder or other device to precisely regulate motor speed and torque.
  • This closed-loop control results in extremely accurate speed tracking and positioning capabilities.
  • Often used for demanding applications like machine tools, packaging, printing presses, and metal rolling where precision is critical.
  • Most complex and expensive type of VFD, but it provides the highest performance.


Regenerative VFDs:

  • Special VFDs are designed to capture braking energy from decelerating motors and reuse this power.
  • The regenerated power can be used to run other attached motors, saving energy.
  • Used in applications with frequent starts/stops or reversing loads. Examples are elevators, cranes, and centrifuges.
  • It is more costly than standard VFD drives but provides efficiency benefits through energy recovery.

 

Key Factors for Selecting a Variable Frequency Drive

  • Motor Compatibility: Ensure the VFD is suitable for controlling the AC motor type (induction or synchronous).
     
  • Power and Voltage: The VFD must match the voltage, horsepower, and amperage ratings of the connected motor.
     
  • Speed Range: Verify the VFD provides the precise speed range needed for an application.
     
  • Environmental Rating: VFD enclosures must suit the operating environment - indoors, outdoors, etc.
     
  • Programming and Control: VFDs offer different levels of programmability and process control integration.
     
  • Harmonic Mitigation: VFDs can generate power harmonics, so harmonic filters may be required.
