What is a VFD, and How Does it Work?
If you've been around AC electric motors for a while, you've probably heard about Variable Frequency...
Adding a motor speed control to your application can give you improved performance, savings on your energy bill, and protection of your motor and the equipment it drives, resulting in less downtime and savings on your maintenance bill.Contact Us
Variable Frequency Drives (VFDs) for controlling the speed and torque of three-phase motors. Excellent versatility for applications at or above 25% of motor rated speed.
Speed and torque controls for DC motors. Best suited for applications with high torque requirements at low speeds.
Reduced voltage starting to limit the stress on motors and loads on startup. Reduced inrush current for less strain on the power system and possible cost savings on industrial electricity charges.
Ever since we started using electric motors to move the world around us, we’ve been trying to mitigate issues with starting and stopping. A simple on/off switch that cuts power isn’t sufficient; they often cause voltage fluctuations that create overload situations, resulting in overheating. Companies like General Electric have spent decades trying to come up with a fine motor control solution. Advances in microcomputer technologies from the 1960s through the 1980s contributed to the advances in electric motor control that followed this period and continues today. The precision, response, speed-range, and performance of electric motors have grown exponentially.
Today, there’s a plethora of different types of electric motor controls for AC and DC motors. Motor starters, variable frequency drives (VFD), and motor fan speed controllers, to name a few. These electronic control units have quite a few possible capabilities:
These controls give the user precise control of the motor, allowing for a more smooth, accurate operation.
