Infinitum has introduced the Aircore EC+ motor, a new addition to its existing Aircore EC motor platform aimed at power-intensive cooling applications, according to a July 6, 2026 report from HVAC/P. The company positioned the motor in the context of rising electrical power demand tied to artificial intelligence infrastructure and broader electrification trends across commercial and industrial facilities.
Infinitum builds cooling-application motors around what it calls Aircore technology, and the EC+ variant is designed to add power-quality and reliability features on top of the existing Aircore EC platform rather than replace it, per HVAC/P's report.
Aircore EC+ Motor Power-Quality Features
The Aircore EC+ motor integrates Active Front End, or AFE, technology, which Infinitum says reduces harmonic distortion below the limits set by IEEE 519, the industry standard covering harmonic control in electrical power systems. Reducing harmonics at the motor level is intended to limit electrical interference that can otherwise be introduced back onto a facility's power system by variable-speed motor drives.
Active Front End is a motor-drive technology that uses active switching components, rather than a passive diode bridge, to convert incoming AC power to DC for the motor's internal use, a design commonly associated with lower harmonic distortion and the ability to support power factor correction and regenerative braking in variable-speed drive systems. IEEE 519 is a widely referenced industry standard that sets recommended limits for harmonic voltage and current distortion at the point where equipment connects to an electric utility or facility power system.
Standard features on the Aircore EC+ motor include an IP65-rated enclosure, high-resistance grounding with power-loss ride-through capability, and hybrid ceramic bearings that are non-conductive and corrosion-resistant, according to HVAC/P. The IP65 rating denotes protection against dust ingress and low-pressure water jets from any direction, a sealing level commonly specified for motors operating in industrial or outdoor-adjacent mechanical spaces.
Power-loss ride-through capability allows a motor to continue operating, or to resume operating without a full restart sequence, through brief interruptions or dips in incoming power, rather than tripping offline. Hybrid ceramic bearings use ceramic balls in place of steel ones inside the bearing, which prevents electrical current from passing through the bearing and causing the pitting or fluting damage that can result from stray shaft currents in motors driven by variable-frequency drives.
High-resistance grounding is a grounding scheme used in some industrial power systems to limit fault current if a single line makes unintended contact with ground, allowing equipment to keep running through that first fault rather than shutting down immediately. In motors paired with variable-frequency drives, stray electrical currents traveling through the motor shaft and into standard bearings are a recognized cause of premature bearing wear, which is why bearing designs that block that current path, such as hybrid designs using non-conductive ceramic balls, are used in some industrial and commercial motor applications.
Infinitum's Aircore Motor Platform
The Aircore EC+ motor builds on Infinitum's existing Aircore EC motor platform rather than replacing it, according to HVAC/P's July 6 report. Electronically commutated, or EC, motors are a broad category of motors used across HVAC and industrial equipment that rely on electronic controls rather than mechanical commutators to manage motor speed and torque; manufacturers across the industry market EC-based products for a range of fan, pump and compressor applications. HVAC/P's report did not detail additional specifications of the underlying Aircore EC platform beyond noting that the EC+ variant adds power-quality and reliability features to it.
Industry Context: Power Demand and Data Center Cooling
Infinitum positioned the Aircore EC+ motor specifically in relation to rising power demand driven by artificial intelligence infrastructure and broader electrification trends, HVAC/P reported. Data centers supporting AI workloads have drawn attention across the electrical and mechanical trades for their high and growing power density, which in turn increases the electrical load placed on the cooling equipment, including motors, that keeps that computing hardware within operating temperature limits.
Power quality has become a more prominent design consideration for motors and drives serving those facilities, since harmonic distortion, voltage sags and other electrical disturbances can affect both equipment reliability and a facility's compliance with grid-connection requirements such as IEEE 519. Electrification trends, including the broader shift toward electric-driven mechanical and industrial equipment, have similarly added electrical load to power systems that were not always designed with that level of demand in mind.
Availability of the Aircore EC+ Motor
HVAC/P's July 6 report on the Aircore EC+ motor did not include pricing or a specific availability date. Infinitum is marketing the motor toward power-intensive cooling applications, building on the Active Front End technology, IP65 enclosure rating, grounding and bearing features that the company says distinguish it within its existing Aircore EC motor lineup.
