AC Drives
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.
DC Drives
Speed and torque controls for DC motors. Best suited for applications with high torque requirements at low speeds.

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:
- Start and stop the motor
- Reverse the rotation of the motor shaft
- Regulate and adjust the speed of the motor
- Regulate and limit the amount of torque on the load
- Protect against overload and failures due to overheating
- Protect against electrical faults from the source of power
These controls give the user precise control of the motor, allowing for a more smooth, accurate operation.
