Infinitum Redefines HVAC Efficiency with High-Performance Aircore EC+ Motor
Infinitum is pushing the boundaries of energy-efficient motion control with the launch of its Aircore EC+ motor. By integrating advanced PCB stator technology and active front-end electronics into a compact, unified package, the company offers a drop-in replacement for traditional motor-VFD configurations in demanding HVAC, fan, and pump applications.
At the heart of the Aircore EC+ lies a unique architectural approach that replaces bulky iron-core stators with a lightweight, flat-stacked PCB design. This innovation delivers up to 90% efficiency by drastically reducing eddy current losses and material mass. Beyond size reduction, the system addresses common power quality issues in industrial environments. By incorporating active front-end (AFE) technology, the motor mitigates harmonic distortion—a frequent culprit behind transformer damage, breaker tripping, and excessive thermal stress in power distribution systems. This built-in capability eliminates the necessity for external filters, effectively lowering the total cost of ownership and installation complexity for facility managers.
Operational durability is further enhanced through an IP65-rated enclosure and hybrid ceramic bearings. These non-conductive, corrosion-resistant components allow the Aircore EC+ to maintain reliable performance in harsh, outdoor, or high-humidity conditions where traditional motors might face premature failure. Furthermore, the motor's high ground resistance ensures consistent uptime even during standby power events, a critical requirement for infrastructure where unplanned downtime directly translates to revenue loss.
The Aircore EC+ platform is currently available in four frame sizes (13 to 20), supporting a power range from 1 HP to 15 HP and operating at speeds between 100 and 5040 RPM. With integrated electronics providing the precise variable-speed control traditionally relegated to external variable-frequency drives, the system provides a streamlined solution for cooling fans, heat pumps, and industrial furnace applications. By minimizing the footprint while maximizing electrical efficiency, Infinitum is providing engineers with a viable pathway toward more sustainable, lower-maintenance industrial operation.
