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...

A variable speed motor drive is a type of motor that is used to control the speed of a fan, pump or compressor based on an input signal. This can be achieved by using a simple pulley system or by using an electronic feedback loop. When can you use such a type of motor? Motor drives are used in many ways, depending on how you want to use them. For example, if you need a motor to run at different speeds and/or you need to control the speed of a motor, then it is more efficient and cost effective to use a variable speed drive. This type of motor drive can also be used for controlling the direction of your motors. If you want your motors or other equipment to turn off automatically after being left idle for some time period (e.g., when doing assembly line work), then this kind of automatic shutoff can be accomplished using an intelligent motor controller (IMC). How does a variable speed motor work? You might be wondering how a variable speed motor works. To understand this, it helps ...
