What Calnetix Technologies does

Calnetix Technologies, LLC is a privately held electromechanical systems company headquartered in Cypress, California, founded circa 2000, that designs and manufactures high-speed permanent magnet (PM) motor generators, active and passive magnetic bearings, silicon-carbide (SiC)-based variable frequency drives, magnetic bearing controllers, and integrated turbomachinery systems. Its technology stack is vertically integrated: PM machines operate at 30,000–100,000 rpm (with designs exceeding 450,000 rpm), are supported on the company's proprietary oil-free magnetic bearings (including PM-biased homopolar designs), and are driven and controlled by Calnetix's own VFDs and controllers. The portfolio is organized under three sub-brands — Magnaforce (PM motors and generators), Powerflux (magnetic bearings), and Enercycle (SiC-based bidirectional inverters for hybrid-electric powertrains). A wholly-owned subsidiary, Access Energy Heat & Power Solution, commercializes turboexpanders and Organic Rankine Cycle heat recovery systems for industrial waste-heat-to-power applications.

The company operates as an OEM supplier selling directly to defense and aerospace primes and industrial OEMs, with named end users including the U.S. Military, U.S. Army, and U.S. Navy. It addresses two primary verticals: Defense and Aerospace (hybrid-electric aircraft systems, export power inverters, high-speed starter generators, terrestrial power generation, mission-critical cooling) and Industrial (air/gas movement and control, compression, pumping, turbocharging, turboexpansion, and emerging sustainable hydrogen systems). Revenue is generated through hardware sales of engineered components and integrated subsystems, with power levels spanning 10 kW to over 1 MW and documented efficiency improvements from approximately 95% to over 98% using SiC switching in ORC systems. Calnetix has no parent company, no disclosed venture or private equity backing, and no public filings; pricing and revenue figures are not publicly disclosed.

Core offering

Calnetix Technologies designs and manufactures high-speed electromagnetic drive solutions for OEMs, including permanent magnet motor generators, active and passive magnetic bearings, magnetic bearing controllers, variable frequency drives, SiC power electronics, turboexpanders, and ORC heat recovery systems. These products are integrated into mission-critical defense, aerospace, marine, oil and gas, and motorsports applications, with the company operating as a direct OEM supplier and technology licensor.

Product overview

Calnetix Technologies provides electromagnetic drive solutions utilizing high-speed technologies for defense, aerospace, and industrial applications. The product portfolio centers on five core technology pillars: High-Speed Permanent Magnet Motor Generators (Magnaforce™), Active and Passive Magnetic Bearings, Variable Frequency Drives (VFDs) with silicon carbide (SiC) technology, and Magnetic Bearing Controllers. These products work synergistically as an integrated system — Magnaforce™ PM machines are supported on Calnetix's proprietary active magnetic bearings, driven by their Variable Frequency Drives and controlled via Magnetic Bearing Controllers. The company also offers specialized products like the Enercycle™ DC-1000 bidirectional inverter for power conversion and Turboexpanders with ORC heat recovery systems for industrial energy efficiency. All products emphasize high-speed rotating machinery, oil-free operation, high efficiency, power density, and low total cost of ownership across applications including aerospace power generation, turbomachinery, hydrogen systems, marine, oil and gas, and motorsports.
