VFD Control Panel Basics
A VFD, short for variable frequency drive, is a type of a motor controller that powers and controls a motor and its speed with varying frequency (Hz) and voltage. A VFD control panel consolidates VFD’s and any associated motor control or circuit protection devices in an enclosure, protecting them from moisture, corrosion, dust, and other conditions. The most common NEMA ratings for VFD control panel enclosures are NEMA 1, NEMA 3R, NEMA 4 and NEMA 4x. A VFD control panel typically houses a selection of control panel components including a VFD, line reactors, harmonic filters, circuit breakers, surge protectors, motor starters, soft starters, a bypass, and some kind of cooling unit, as VFD’s tend to produce a lot of heat.
VFD control panels are available in a wide variety of power ratings, and are used across large-scale industrial applications like pumping, drilling and to control other heavy-duty equipment.
Is a VFD Right for Me?
VFD’s and VFD control panels have several advantages including energy savings, performance, durability and less maintenance. Electric motor systems can take up a good chunk of power, so if you have equipment that does not need to be running at full speed all of the time, a VFD might be a good choice. A VFD control panel only draws power when it’s required. That is to say, as a motor’s requirements change, the VFD can change the motor speed accordingly. This benefits you on all fronts in terms of energy savings, performance and durability. Further, because VFD’s are an AC drive, there is less maintenance required since you’re not dealing with a DC motor or a transmission. However, one thing to remember is the high level of heat they produce. It’s important to have proper air flow in the control panel so the VFD and its components do not overheat. VFD's are most commonly compared to soft starters, however soft starters are more compact and can be used just when speed and torque control are needed.
