Infinitum

Next-gen air-core motors for mobility, industry

Overview

Infinitum Electric designs and sells electric motors that use air core technology to deliver smaller, lighter, and more efficient motors for mobility and general-purpose applications. The air core design removes the heavy iron stator, while a printed circuit board (PCB) stator eliminates acoustic noise and torque ripple, resulting in higher power output relative to weight. The motors are intended for manufacturers and businesses that need robust, efficient propulsion for vehicles and industrial machinery, with the company selling directly to these B2B customers. Infinitum differentiates itself through its air core approach, reduced motor weight, quieter operation, and a collaborative, transparent culture that offers competitive benefits such as stock options. Its goal is to scale production and deployment of high-performance motors across a wide range of applications by partnering with manufacturers and advancing motor technology.

Simplify's Take

What believers are saying

  • HVAC veteran Buddy Doll joined the board in May 2026 to accelerate air-core motor adoption in data centers amid rising energy constraints.
  • Infinitum launched EC Fan Systems in 2026 with industry-leading Fan Energy Index, combining fan, motor, and VFD into one optimized platform for data centers.
  • Rockwell Automation will exclusively distribute Infinitum’s integrated VFD and high-efficiency drive systems for industrial applications starting late 2024, expanding market reach.

What critics are saying

  • Rockwell’s 2026 launch of 20% more efficient proprietary HVLS motors directly threatens Infinitum’s HVAC share with a superior product from a dominant OEM partner.
  • Siemens’ 2026 Blue Motor series offers 15% lower cost per kW and AI-driven predictive maintenance, eliminating Infinitum’s efficiency advantage in data center cooling.
  • Infinitum’s $40M Series C funding is insufficient for planned 200% workforce expansion and Mexico automation, creating critical liquidity risk as investor Riverstone exits.

What makes Infinitum unique

  • Infinitum uses patented air-core PCB stators to eliminate iron cores, achieving 50% lighter and smaller motors with 10–65% higher efficiency.
  • The company reduces harmonics below IEEE 519 limits via integrated Active Front End technology, enabling cleaner power for AI data centers without extra filters.
  • Infinitum’s Aircore EC motors maintain 20% higher efficiency at low speeds than conventional EC motors, solving critical limitations in variable-load HVAC applications.
