Overview

Variable-frequency drives (VFDs) are devices used to control the speed and torque of electric motors by varying the frequency and voltage of the power supplied. VFDs are commonly used in applications like HVAC systems, industrial machinery, and pumps where precise motor control improves efficiency and performance.

FAQ

How do I ensure the VFD is shipped safely to my location?

Use a reputable transport service that specializes in electronic equipment. Ensure the VFD is securely packaged to prevent damage during transit and consider insuring the shipment.

What is the maintenance schedule for a variable-frequency drive?
