Variable Frequency Drives: What Are They, and Why Use One?

What are Variable Frequency Drives?

Variable frequency drives (VFDs) are a common electrical supply tool. These motor controllers vary frequency and voltage supply to an electric motor. These are often known by different terms, including adjustable speed drive, AC drive, microdrive, inverter and variable speed drive. They’re chosen by those in the industry due to their efficiency and suitability for a number of common applications.

VFDs are often used in high voltage wiring in Alexandria, VA. Read on to find out more about why this equipment is favored by electrical professionals, and which applications it’s best suited for:

  • How it works: A VFD drives the motor by controlling the frequency and voltage. It also can ramp the motor up or down during a start or stop. This is related to keeping speed control of the motor, and these kinds of adjustments are useful in a number of applications. Today’s drives have evolved to take on networking and diagnostic capabilities, thereby improving performance and making VFDs the leading choice in a number of industries. About three-quarters of all VFDs are used for fans, compressors and pumps. The flexibility of this kind of drive lies in its converter, which manages the motor’s load and can simply increase or decrease to meet speed requirements.
  • Efficiency: One of the leading reasons businesses choose VFDs is for their excellent efficiency. They can save energy and improve systems management instantly by managing workloads. That’s because VFDs match the speed of the drive to process requirements, reducing peak demand costs. This individualized system works well to reduce energy consumption and save money.
  • Extend equipment life: VFDs also reduce the stress placed on machines, thereby extending their lifetimes or allowing for smaller motors to be used. Additionally, equipment will be protected from hazards like electrothermal overloads and overvoltage, which can lead to costly damage and repairs. The wear and tear on your company’s investments will be reduced substantially by using the right drive. Also, VFDs allow for conversion of power in a range of hybridization applications.
  • Better process controls: By using VFDs and adjusting load maintenance, production will increase because there will be fewer mistakes and errors. For example, it’s easy to get rid of inconsistent starts on conveyors or belts by adjusting motor speed.
