Around 25 percent of the world’s total electrical energy is used by electric motors used in industrial applications. These are particularly conducive for energy savings using variable frequency drives in centrifugal load applications, and the variable frequency drives global market breakthrough for all applications is still relatively small. This exact lack of penetration emphasises notable efficiency improvement opportunities for new drive installations.
A variable frequency drive is a type of adjustable speed drive that’s commonly found in electric and mechanical drive systems used to manage torque and AC motor speed by varying input frequency and voltage. Frequency drives are used in applications ranging from compressors and large mill drives, to the smallest of appliances. You can find a variable frequency drive for sale online quite easy and pick one for the application you need.
Over the past few decades, thanks to the many technological advancements in the frequency drive field, their prices have been significantly reduced and their performance improved. This is a result of the advancements made in the control and simulation technologies, drive topologies, hardware and semiconductor switching devices.
A lot of fixed-speed motor applications that are supplied from the AC line power directly, could save much energy when operated at variable speeds implemented by a frequency drive. Such energy cost savings are particularly pronounced in fan applications and variable-torque pumps, where the power of the load and the torque vary with the square and cube of the speed.
The AC motors which are used in frequency drives are usually three-phased induction motors. In some instances, single-phase-type motors can be applied, but three-phased motors are the better and the preferred type. Different types of synchronous motors provide more advantages in specific situations, but the three-phase induction type is suitable for pretty much every purpose and is the superior economical choice. Besides variable frequency drives, in some appliances, fixed-speed drives are used as well.
So when looking for a variable frequency drive for sale, whether that’s online or not, make sure you know what you’re looking for. However, regardless of what you’re looking to apply the drive to, you can rest assured that you will find improvements in the application’s flow, pressure, temperature, acceleration, torque, tension and speed in both industrial and residential applications. Moreover, modern drives have never been safer than they are today, and come with extra safety features to compliment that. As a means for precaution, it’s always a good idea to read the manual before using the device. In a case of a blackout, treat it like you would treat a power generator – keep it stored in a ventilated and cool area away from sparks and heat.
