Variable Frequency Drives

Variable Frequency Drives (VFDs) control AC motor speed by adjusting output frequency and voltage. Used across industrial and commercial applications, VFDs help improve process control, reduce startup stress, and support efficient operation for pumps, fans, conveyors, compressors, and other motor-driven systems.

Shop VFDs by voltage, phase, horsepower, enclosure, and application requirements, including options for variable torque and constant torque loads, plus related categories such as AC VFDs, Medium Voltage VFDs, and VFD Accessories.

Need help selecting the right VFD? Contact our team here or call us at 1-800-800-2261 for assistance with voltage, phase, horsepower, enclosure type, and application requirements.
