Variable Frequency Drives Market Flourishing in North America
The variable frequency drive (VFD) market in North America is experiencing tremendous growth over the past few years and is expected to continue significant expansion over the upcoming decade. VFDs offer numerous benefits over traditional constant speed motor controls and their adoption across various industries is driving the market demand. This article provides an in-depth analysis of the North America VFD market trends, major applications, leading players and future outlook.
Introduction to Variable Frequency Drives
A variable frequency drive, also known as an adjustable speed drive, adjustable frequency drive, AC drive or inverter, is a type of motor controller that drives an electric motor by varying the frequency and voltage supplied to the electric motor. Without the ability to control motor speed, most electric motors run at a fixed speed based on the utility frequency and number of electromagnetic poles.
VFDs allow for controlling the rotational speed of an AC electric motor by controlling motor input frequency and voltage. They are particularly suitable for AC induction motors which require variable speed control in many industrial processing, HVAC, pumps, machine tools, and other applications. Variable speed capability is useful for precise control, energy savings and process optimization in numerous industries.
Major VFD Applications in North America
Pump Control:
Pump applications account for over 30% of North America's total VFD market. VFDs provide efficient and precise speed control of centrifugal pumps used in various industries like water/wastewater, oil & gas, chemical, food & beverage, etc. They help reduce pumping energy usage by up to 70% compared to uncontrolled pumps.
HVAC Systems:
Heating, ventilation and air conditioning (HVAC) systems use VFDs to vary airflow and optimize performance based on building occupancy and weather conditions. VFDs integrated into air handling units, fans, chillers, compressors and other devices lower HVAC energy consumption by 10-50%.
Material Conveyers:
Materials handling equipment like conveyor belts, lifts, elevators are often driven by variable speed electric motors. VFDs allow for regulating the speed of these devices according to production demands to save energy and increase throughput.
Machine Tools:
Machining centers, lathes, grinders and other machine tools vary spindle/axle speeds based on material type and cutting conditions. VFDs control these variable speed machine tool motors for improved productivity and surface finish quality compared to fixed speed operation.
Packaging Equipment:
Packaging lines in food, pharmaceutical, and other industries use VFDs to modulate flow rates, fill levels, and drive speeds of conveyors, augers, mixers, piston pumps etc. This ensures accurate product dosing/filling and synchronization of packaging equipment.
