Eve Air Mobility has selected BETA Technologies to supply the electric pusher motors for its conforming prototypes and future production electric Vertical Take Off and Landing aircraft.

The collaboration supports Eve’s supply chain for its aircraft, which currently has a backlog of 2,800 orders. The agreement represents a potential 10-year opportunity for BETA Technologies of up to $1 billion. It follows an initial evaluation period during which Eve purchased, tested, and validated the performance of the BETA motors in its Engineering Prototype, ahead of a first flight expected in late 2025 or early 2026.

Johann Bordais, Chief Executive Officer of Eve Air Mobility, commented, “Integrating Beta Technologies into our supply chain is a pivotal milestone in advancing our eVTOL program. Their electric motor technology will play a critical role in powering our aircraft during cruise, supporting the maturity of our propulsion architecture as we progress toward entry into service. This collaboration underscores Eve’s commitment to working with suppliers that share its rigorous safety standards and deliver proven engineering solutions, driving performance, efficiency, and sustainability.”

BETA Technologies designs and manufactures its proprietary electric propulsion systems, which it states offer industry-leading power-to-weight ratios and energy-conversion efficiencies. The simple designs incorporate segment redundancy and feature significantly fewer parts than traditional aircraft engines, which the company says contributes to high safety and low cost.

Kyle Clark, CEO and Founder of BETA, added, “We’re excited to work with Eve Air Mobility and supply our electric propulsion technology to their production program. Our pusher motors have already proven high performance and reliability in thousands of demanding real-world operations across the globe, and our manufacturing capability will allow us to deliver these systems at scale to support Eve’s aircraft. This collaboration is another step in moving electric aviation toward commercialization and adoption”

Eve’s eVTOL aircraft utilizes a lift + cruise configuration, featuring eight dedicated propellers for vertical flight and fixed wings for cruise, with no moving parts in flight. The aircraft’s electric pusher is powered by dual electric motors, providing propulsion redundancy. This configuration allows separate systems to be optimized for each flight phase, simplifying maintenance, reducing operational costs, and minimizing the sound footprint.

BETA Technologies joins other suppliers supporting the development, including BAE Systems for batteries, Garmin for avionics, Honeywell Aerospace for external lighting, Intergalactic for thermal management, and Nidec Aerospace for lifter motors.

The current stage of development involves comprehensive tests with the prototype to evaluate every aspect of the aircraft’s operation and performance.
