Core offering

Phi-Power AG designs and manufactures axial flux electric motors and generators for OEM automotive, motorsport, and industrial customers. The portfolio includes the Phi-Range family (Phi301, Phi271, Phi27S), the legacy-compatible PhE-Range (PhE381, PhE382), bespoke range-extender generators, and official European distribution of Rinehart Motion Systems automotive inverters (PM100, PM150, PM250). The company also delivers custom design, prototyping, small-to-medium volume production, and powertrain integration/motorsport engineering services.

Product overview

Phi-Power AG offers a hardware-focused product portfolio centered on a single core technology (axial flux electric machines) deployed across two motor ranges plus distributed power electronics. The Phi-Range is the company's flagship new-generation axial flux motor family (currently comprising the Phi301, Phi271, and Phi27S), designed for class-leading power and torque density with rugged IP6k9k closed-housing construction. The PhE-Range (PhE381, PhE382) is a legacy-compatible sub-family whose mechanical and electrical interfaces drop into existing EVO Electric installations while delivering the performance benefits of Phi-Power's axial flux topology. Complementing the motors, Phi-Power is the official European distributor of Rinehart Motion Systems (RMS) automotive inverters (PM100, PM150, PM250) and sells them either standalone or pre-matched to a Phi-Power motor. Custom axial flux range-extender generators and bespoke design, integration consultancy, and motorsport engineering services round out the offering, making the portfolio a platform-plus-modules architecture: a unified axial flux technology base instantiated in multiple motor SKUs, paired with third-party power electronics and tailored engineering services.

Targeted at racing and high-performance applications.
• PhE382 Axial Flux Motor PhE382 is part of the PhE-Range of axial flux motors designed to be interface-compatible with EVO Electric machines while delivering the performance benefits of Phi-Power's axial flux technology. Targeted at racing and high-performance applications.
• RMS PM100 Inverter (100 kW) PM100 is a 100 kW automotive inverter from Rinehart Motion Systems, distributed and supported by Phi-Power as official European reseller. Available in DX (300Arms continuous / 350Arms peak, 100-400VDC) and DZ (150Arms continuous / 200Arms peak, 300-800VDC) variants; shipping in small quantities as DV-stage pre-production hardware.
• RMS PM150 Inverter (150 kW) PM150 is a 150 kW automotive inverter from Rinehart Motion Systems distributed by Phi-Power, mechanically identical to the PM100 but 122mm longer to accommodate larger DC link capacitors and a larger power module. PM150 DX: 450Arms continuous / 450Arms peak, 100-400VDC. PM150 DZ: 225Arms continuous / 300Arms peak, 300-800VDC.
• RMS PM250 Inverter (250 kW) PM250 is the largest inverter from Rinehart Motion Systems distributed by Phi-Power, optimized for size and weight in high-power performance and heavy-duty applications. PM250DZ weighs only 17.5 kg with a repetitive peak power output over 360 kW, delivering class-leading power density.
• Axial Flux Range Extender Generator (RangeX) Bespoke axial flux range-extender generators (RangeX brand) leveraging the disc-shaped topology's short length and high torque density to fit constrained installation envelopes; generators are tailored to the engine's speed-torque characteristic and integrated with the active parts for OEM customers.
• Custom Axial Flux Machine Design Service End-to-end bespoke axial flux machine design service covering electromechanical modelling, detailed design, prototype build, testing, and small-to-medium-volume production runs, including P2 hybrid machine and bespoke traction motor variants. Targeted at OEM and industrial customers.
• Electric Powertrain Integration Consultancy Consultancy services assisting customers with integrating Phi-Power motors into existing electric drive systems and troubleshooting electric powertrain integration challenges.
• Electric Motorsport Engineering Service Rapid-response motorsport engineering service leveraging Phi-Power's experience working with motorsport teams to produce designs and supply parts within the short lead times demanded by racing applications.
