Motor drives help to increase the productivity of your equipment by increasing torque and reducing motor speed. However, it’s important that you pick the right and  Perfect VFD Drives   for your application and motor power factor (PF). This will ensure that your motors are protected from overloading conditions and the efficiency of your system is at its peak. Proper motor selection Motor power factor is the ratio of real power to apparent power. It is usually expressed as a percentage, and it can be calculated by dividing the actual current in amperes by the nameplate current in amps. The best motor power factor to use depends on your application. In general, you should select a VFD drive with a motor's rated voltage and frequency (60Hz), horsepower rating, frame size (if applicable), type of enclosure (open or enclosed), shaft diameter and length, mounting style (footless vs pedestal mount), speed range required for your application along with any additional features needed s...

You may have heard the term Variable Speed Drive Motor (VFDs) before and wondered what they do. Or perhaps you're considering replacing your existing motor starter with a newer version that uses  VFD technology. If so, this article will help clear up some of the confusion around these devices.  We'll talk about why electric drives are important for industrial applications, how they work and what benefits they offer over other types of motor starters. Why Use Electric Drives? Variable frequency drives (VFDs) are used to control the speed and direction of electric motors in many industries. They can be found in manufacturing, mining, oil and gas, food processing, pulp and paper, steel and other metal industries. VFDs work by varying the frequency of an AC power source to match with that of an AC motor's operating frequency.  This allows you to control how much torque is being produced by your motor without having to change its voltage or current levels--which means no...
