VFD Control System Basics
What is a VFD Control System?
A VFD, short for variable frequency drive, is a type of a motor control electrical device for starting and controlling an AC inductive motor and its speed with varying frequency (Hz) and voltage. A VFD Control System consist on an AC control panel housing the VFD and any associated motor control or circuit protection devices in an enclosure, protecting them from electrical shocks, fires, moisture, corrosion, dust, and other conditions. The most common NEMA ratings for VFD control panel enclosures are NEMA 12, NEMA 3R, and NEMA 4x. A VFD control panel typically houses a selection of control panel components including a VFD, harmonic filters, line reactors, surge protectors, a bypass, circuit breakers, motor starters, soft starters 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 such as elevators, rock crushing machines, and water & sewer treatment plants and water conservation for agricultural systems.
In the USA roughly 50% of the total electrical energy generated is consumed by AC Inductive motor equipment. Variable frequency drive technology offers a cost-effective method to match motor speed to load demands and represents a state-of-the-art opportunity to reduce operating costs and improve overall productivity.
IndustLabs Intelligent Series VFDs
The IndustLabs Intelligent Series AC drive VFD Control Panels are power by Fuji electric VFDs for controlling AC motor. The only drives on the market with a default 3 year manufacturers warranty. IndustLabs is a leader in bringing world class intelligence to our VFD product including our own Internet of Things (IoT) platform where your VFDs can be monitored and controlled remotely. You can even set alert thresholds and notifications to reduce the Mean Time to Repair for your facilities to ensure your production continues.
IndustLabs is a full service provider of AC drive VFD Packaged Solutions. We can build your VFD to your needs and specs. From fractional Horsepower to large 1000+ Horsepower motors. Below is a list of some of our most common applications and features including control the speed of ac motor.

VFDs have long been used as a primary source of cost of energy reduction as well as ambient noise. Unlike legacy methods; such as belts, sheaves, and gear boxes; VFDs control the speed and amperes that can be drawn by an electric motor to reduce energy cost and actually limit the speed of a motor.
According to the EPA it is possible to achieve a 50% – 85% reduction in energy cost through the use of Variable Speed Drives. A far greater reduction than the use of mechanical flow control devices such as dampers or valves. IndustLabs also has a custom algorithm to slowly start drives to reduce the initial energy draw when starting motors which can increase the life of a drive by up to 70%.
IndustLabs can design a VFD control systems that can vary the adjustable speed drive of ac motor based on input data such as pressure sensors and we can provide remote operations support to changing drive speed without having to send someone to an unmanned location. Through our in-house developed IoT platform custom built for VFD operation we can provide reporting on energy usage, drive speed as compared to input sensors such as pressure sensors, and we can alert on any of these parameters including drive or motor failure.
