Controller Targeted at Printed Industrial Motors Slashes Power-Line Harmonics
The Aircore EC+ is an improved version of Infinitum’s motor system platform offering a premium feature set that improves power quality, reliability, and performance for cooling applications used in power-intensive facilities. Aircore’s control electronics virtually eliminate the power-line harmonics produced by traditional variable frequency drives (VFDs) that can degrade electrical performance, reduce usable power, and degrade reliability.
By maximizing available power and electrical capacity, Aircore EC+ enables customers to do more work with smaller power bills. Features include:
- Integrated active-front-end (AFE) technology: Available integrated AFE technology within the motor’s VFD reduces harmonics at the source and below IEEE 519 limits. It thus delivers cleaner power without the added cost, footprint, and power losses of conventional passive and active filters.
- Standard IP65 enclosure: Heavy-duty exterior protects against dust, dirt and water, allowing motors to operate reliably in harsh outdoor or wet environments.
- Standard high-resistance ground: Delivers normal operation during an electrical ground fault and reduces the chance of equipment failure. Power-loss ride-through capability enables systems to continue operating during standby power.
- Standard hybrid ceramic bearings: As compared to standard bearings, hybrid ceramic bearings don’t conduct electricity and resist corrosion, enhancing durability, reliability, and efficiency in high-performance applications.
”The Infinitum design delivers a near-sinusoidal waveform with harmonic distortion reduced to well below the IEEE 519 standard, far outperforming traditional passive filtering systems that typically only reduce harmonics to 10%,” said Giselle Canahuati, Senior Consultant, Frost & Sullivan.
“Operators of power-intensive facilities are facing unprecedented pressure to maximize uptime, improve efficiency, and support growing power demands without expanding infrastructure," said Ben Schuler, founder and CEO of Infinitum. "By delivering cleaner, more resilient power, Aircore EC+ helps customers improve reliability, unlock additional electrical capacity, and maximize the value of every kilowatt."

Lee is the author of the popular PowerBites series.
Lee Goldberg is a self-identified “Recovering Engineer,” Maker/Hacker, Green-Tech Maven, Aviator, Gadfly, and Geek Dad. He spent the first 18 years of his career helping design microprocessors, embedded systems, renewable energy applications, and the occasional interplanetary spacecraft. After trading his ‘scope and soldering iron for a keyboard and a second career as a tech journalist, he’s spent the next two decades at several print and online engineering publications.
Lee’s current focus is power electronics, especially the technologies involved with energy efficiency, energy management, and renewable energy. This dovetails with his coverage of sustainable technologies and various environmental and social issues within the engineering community that he began in 1996. Lee also covers 3D printers, open-source hardware, and other Maker/Hacker technologies.
Lee holds a BSEE in Electrical Engineering from Thomas Edison College, and participated in a colloquium on technology, society, and the environment at Goddard College’s Institute for Social Ecology. His book, “Green Electronics/Green Bottom Line - A Commonsense Guide To Environmentally Responsible Engineering and Management,” was published by Newnes Press.
Lee, his wife Catherine, and his daughter Anwyn currently reside in the outskirts of Princeton N.J., where they masquerade as a typical suburban family.
