Inverter Drives

An inverter drive (also known as variable frequency drives or VFD) is a type of variable speed drive that allows you as the user to adjust the speed or output. Inverter drives allow AC power to be converted to DC providing the user with precise control. Inverter drives are also ideal for helping to reduce waste or loss of electrical energy in a range of applications.

How do inverter drives work?

Inverter drives are controlled by inputting specific frequencies or parameters into the device. This allows for greater control over your machinery and operations with more precision. Inverter drives are situated between an electrical supply and a motor, with the inverter allowing the power to be regulated to suit the application.

Features and Benefits

  • Control small appliances such as desk portable fans or pump loads
  • Larger appliances such as high torque machine control
  • Digital operation LED input screens (for easy parameter setting, input and monitoring)
  • Compact and sleek design (saves space in constricted areas)
  • Easy installation
  • Automatic restarts (varies in models)
  • Emergency stops (varies in models)
  • Safety self-diagnostics (varies in models)
  • Energy saving (not having a constant running frequency can save electricity costs)

Where might I use an inverter drive?

Inverter drives are used in a wide range of industrial applications. Inverter drives are particularly useful for applications that require precise control of speed and torque with motors.

These kinds of drives are used in areas such as small appliances like simple fan and pump loads all the way through to high torque machine control applications. Most inverter drives feature digital operation and commonly featuring an LED display or analogue dial. This provides the user with direct control of the important parameters they ish to set themselves. As result, this makes them easy to set up and monitor or adjust where needed.

Some inverters are very compact, making them easy to install and have many side by side if needed. Many inverter drives have built in security features such as automatic restarts after power failures, emergency stops or safety self-diagnostics that help you control the safety of your environment.
