Infinitum’s Aircore EC+ motor system has been named a finalist in the Sustainable Solutions category for the 2027 AHR Innovation Awards. This new motor combines a variable-frequency drive (VFD), which adjusts motor speed to match demand, with harmonic mitigation to reduce electrical noise. Together, these features can cut real-world energy use by up to 20% while easing the strain on electrical infrastructure. The compact, service-friendly design also simplifies installation and reduces the need for extra parts, offering clear benefits for commercial HVAC upgrades and retrofits.

Codes, power quality, and incentive checkpoints

Energy codes like ASHRAE 90.1 and the International Energy Conservation Code (IECC) promote the use of variable-speed fans and pumps to improve efficiency. Infinitum’s integrated motor control helps meet these code goals by adjusting motor speed based on demand. Harmonic mitigation reduces total harmonic distortion (THD), which is unwanted electrical ripple that can harm equipment and lower power quality. This supports power-quality standards like IEEE 519, helping buildings avoid electrical issues. Many utilities offer rebates for installing high-efficiency motors and variable frequency drives (VFDs). These incentives can lower upfront costs. Always check with your local utility or energy advisor to confirm available rebates and understand the required documentation for qualification.

Who benefits and the business case

Facility managers can see lower energy bills and reduced demand charges by using the Aircore EC+ motor. It also helps free up limited electrical capacity, which is important during building electrification or major equipment upgrades. Contractors gain from fewer external parts like filters, reactors, and long cable runs. This means faster commissioning and less panel space needed. They also benefit from streamlined ordering and live tracking through HVAC365’s Contractor Portal. Property managers and advanced homeowners enjoy quieter and smoother airflow thanks to the motor’s ability to adjust speed precisely. However, professional installation is recommended to ensure proper setup and performance.

How it works and what to spec

The Aircore EC+ motor includes an integrated variable-frequency drive (VFD) that adjusts motor speed to match the actual load. This avoids running the motor at full speed all the time, which wastes energy. Depending on the duty cycle and controls, this can reduce energy use by up to 20%. The motor also has built-in harmonic mitigation, which means it reduces electrical "noise" or distortions in the power supply. This can eliminate or reduce the need for extra external devices like reactors or filters that normally smooth out electrical current. When specifying this motor, check key factors like voltage and phase, horsepower, frame size, enclosure rating, and the ambient temperature where it will operate. Also, confirm compatibility with your building management system (BMS) and that service access is convenient. The motor supports common control protocols like BACnet and Modbus for easy integration with HVAC control systems.

Action plan: assess, model, and source

Start by auditing your top energy users, such as supply and return fans or pumps. Collect their nameplate data, which lists key motor details, and run a simple payback analysis using expected energy savings between 10% and 20%. This helps you estimate the return on investment and decide if the upgrade makes sense. Next, pilot an air handler equipped with an integrated variable-frequency drive (VFD) motor. Check if it maintains comfort levels, lowers total harmonic distortion (THD)—which is unwanted electrical ripple—and reduces the number of panel components and wiring labor. This real-world test confirms performance and installation benefits. When you’re ready to source equipment, explore the available motors and controls at HVAC365.
