FAQ

An AC drive is a device used to control the speed of an electric motor in order to: 

  • enhance process control
  • reduce energy usage
  • decrease mechanical stress on motor control applications
  • optimize the performance of applications that rely on electric motors
     

Your operation runs on a complex system that consists of many dynamic parts, meaning it requires a great level of control to operate smoothly: whether that comes in the form of motion control, motor speed control, servo motion control or otherwise. And so, with the right drives, bring greater intelligence and efficiency to your operations for an overall better performance.

By working with different voltages and frequencies, drives can control the speed of electric motors to align with load demand – instead of running at full speed at all times. In essence, this makes it possible to enhance process control, reduce energy usage and optimize the performance of motor control applications.

 

A variable frequency drive (VFD) controls electric motors by using a range of voltages and frequencies. VFDs also have the capacity to control ramp-up and ramp-down when a motor is either starting up or stopping.

 

Today you can find a wide range of VFDs, with single-phase and three-phase varieties in particular having evolved to suit a number of applications.

Drives also differ when it comes to the methods used to control frequency and voltage, with some relying on harmonic mitigation technology to function.

 

 

Increasingly, energy storage is being used to create hybrid solutions such as DC/DC converters, which help improve performance by optimizing energy. Although there are various energy storage methods available, decreasing battery costs and increasing energy density have made battery utilization the fastest growing and most easily integrated storage medium available today. With a DC/DC converter you can connect to a wealth of sources including batteries, super capacitors, fuel cells, solar panels and the like.
