What Infinitum does

Infinitum (formerly Infinitum Electric, founded 2016 by Ben Schuler) is an Austin, Texas-based manufacturer of air-core axial flux electric motors built on a patented PCB stator architecture, in which copper traces etched onto a thin disc-shaped PCB replace the laminated steel core and copper windings of conventional motors. The unified Aircore platform integrates a Variable Frequency Drive (VFD) using Silicon Carbide MOSFETs and offers an optional Active Front End (AFE) for IEEE 519 harmonics compliance; the core motor is productized across Aircore EC+ Motor Systems (1–15 HP, four frame sizes), Aircore EC+ Fan Systems, Aircore EC+ for Pumps, Aircore Mobility liquid-cooled motors (50–250 kW), and Power Gen alternators (10–150 kW), supported by I-con motor control software, Motor and Fan Selection Tools, Retrofit Services, and Lifecycle Services with up to five-year extended warranties. Manufacturing is dual-shore, with assembly in Round Rock, Texas and a contract manufacturer in Mexico plus a newly opened Saltillo facility, and PCB fabrication is internalized via the wholly-owned subsidiary Circuit Connect, Inc. in Nashua, New Hampshire. Revenue is generated primarily through hardware sales of motors, fans, pumps, and alternators sold via OEM embedded channels (fan providers) and an enterprise retrofit motion with application-engineer-supported project sales, supplemented by service contracts, extended warranty subscriptions, and software/tools that support hardware specification. The company targets data centers, commercial HVAC, industrial pumps, mobility (commercial vehicles, aerospace, marine, construction, agriculture), and power generation customers, and has raised approximately $370M+ across Series A through Series E (including a 2024 Series E extension), a U.S. Department of Energy award, and follow-on working capital from existing investor Riverstone.

Revenue model

1. Hardware Sales — Motors & Fans: Primary revenue stream from sale of Aircore EC+ motors (1–15 HP / 2.2–11.2 kW), Aircore EC+ Fan systems, and Aircore EC+ for Pumps. Custom nameplating and configurable architectures. Power Gen alternators (10–150 kW) and Mobility motors (50–250 kW) sold separately. Customers can also purchase Evaluation Motors to test before buying.
2. Professional & Field Services: Revenue from turnkey Retrofit Services (free assessment, personalized quote, plug-and-play installation, on-site teams, spare parts). Service contracts provide premium support with factory-trained technicians. Lifecycle Services include start-up and commissioning, non-warranty repairs, technical training, on-site services, and recycling. Service rates are published.
3. Lifecycle Service Contracts & Extended Warranty: Service contracts and extended warranty programs (up to 5 years from shipment date in 1, 2, 3, or 4-year increments). RMA/field service technician support and on-site service programs generate recurring service revenue.
4. Software & Motor Selection Tools: I-con Motor Control Software (iOS, Android, desktop) and online Motor Selection Tool (mst.goinfinitum.com) and Fan Selection Tool provide value-add product capabilities supporting hardware sales. Fan Selection Tool requires registration access for submittal generation.

Core offering

Infinitum designs and manufactures air-core Printed Circuit Board (PCB) stator axial flux electric motors with integrated Variable Frequency Drives under its Aircore EC+ platform. The company sells these motors and motor-based packaged products (fans, pumps, mobility traction motors, power generation alternators) primarily to OEMs and industrial/data center end users, alongside retrofit installation services and post-sale lifecycle support.

Product overview

Infinitum offers a single unified air-core motor platform — branded Aircore EC / Aircore EC+ — built on a patented PCB stator architecture with an integrated Variable Frequency Drive (VFD), and extends it across multiple productized packages. The flagship Aircore EC+ Motor System is the core platform (formerly Aircore EC, with Aircore MC folded in), available in four frame sizes up to 15 HP with optional integrated Active Front End for harmonics mitigation. This core platform is then delivered in packaged offerings: Aircore EC+ Fan Systems (integrated fans with five wheel sizes), Aircore EC+ for Pumps (integrated motor + VFD for pumping), Aircore Mobility Motors (50–250 kW traction/propulsion), and the Power Gen alternator (10–150 kW). Service offerings include Retrofit Services and Lifecycle Services (commissioning, extended warranty, on-site services, recycle services, and technical training). Software and tooling built around the platform include the I-con Motor Control Software, the Motor Selection Tool, and the Fan Selection Tool, plus an Evaluation Motor sampling program. Together, these constitute a modular platform-plus-packages architecture that targets data centers, commercial HVAC, industrial facilities, mobility, and power generation.

Direct peers

• Turntide Technologies: Direct peer: Turntide also develops axial-flux / switched-reluctance electric motors targeting commercial HVAC, data center cooling, and electric mobility. Similar product positioning, sustainability-led GTM, and a competing efficiency claim. Both compete in the same air-core / advanced-motor category for the same data center and HVAC buyers.
• YASA (Mercedes-Benz): Direct peer in axial-flux traction motors: YASA develops high-power-density axial-flux motors for automotive and aerospace applications, directly comparable to Infinitum's Aircore Mobility line. Acquired by Mercedes-Benz in 2021, giving it a strategic commercial channel that Infinitum lacks.

Broad incumbents

• ABB: Broad incumbent: Global industrial giant offering the full spectrum of low-voltage and high-voltage motors, drives (e.g., ACS series), and integrated motor-drive packages that compete head-to-head with Infinitum's Aircore EC+ in HVAC, pumps, and industrial automation. Represents the largest competitive threat and the benchmark for unit economics.
• Siemens: Broad incumbent: Siemens' SIMOTICS motor line and SINAMICS drives portfolio competes across commercial HVAC, industrial, and data center applications, with comparable IE5/IE6 efficiency claims and integrated motor-drive offerings. A key bidder in any large data center retrofit or new-build specification.
• Nidec Corporation: Broad incumbent: World's largest manufacturer of small and mid-sized electric motors, including ECM/EC fan motors that directly compete with Infinitum's Aircore EC+ in commercial HVAC and data center cooling. Nidec's scale and global manufacturing footprint make it the dominant cost benchmark.
• WEG Electric: Broad incumbent: Major global motor and drives manufacturer with a strong industrial pump and HVAC motor portfolio. Competes with Infinitum on price-performance for industrial pump and fan applications, particularly in North and South America.
• Regal Rexnord: Broad incumbent: Owns Marathon, Leeson, and Century brands for commercial and industrial motors. Competes with Infinitum across HVAC, pump, and industrial customer segments, and is a common incumbent supplier in data center and industrial facilities.

Others

• Rockwell Automation: Partner and adjacent competitor: Named co-developer and distribution partner for Infinitum's 100k+ low-voltage drives program, but Rockwell's own PowerFlex and Allen-Bradley drives are direct competitive alternatives in any industrial automation customer spec. The partnership is strategic but could shift to a competitive posture at scale.

Regional players

• Johnson Controls: Strategic customer/peer in commercial HVAC: Johnson Controls is both a named HVAC industry reference for Buddy Doll (new board appointee) and a potential OEM customer integrating Infinitum motors into its commercial building systems, but also a competitive supplier of integrated HVAC equipment.

Emerging players

• Vertiv: Adjacent data center player: Vertiv provides thermal management, power, and IT management solutions for data centers, including CRAC/CRAH units and CDU products — exactly the systems into which Infinitum's motors are embedded. Vertiv is a potential large OEM customer and a useful comp for the data center cooling thesis underlying Infinitum's primary growth narrative.
