Eve Air Mobility Selects BETA Technologies for eVTOL Pusher Motors

This article is based on an official press release from BETA Technologies and Eve Air Mobility.

Eve Air Mobility Taps BETA Technologies for Critical Propulsion Systems

In a significant move for the electric aviation sector, Eve Air Mobility has officially selected BETA Technologies to supply the electric pusher motors for its eVTOL (electric vertical take-off and landing) aircraft. The agreement, announced on December 2, 2025, represents a major step toward supply chain consolidation as the industry approaches commercialization.

According to the official announcement, this long-term agreement covers the supply of electric pusher motors for both Eve’s conforming prototypes and its serial production aircraft. Industry reports indicate the deal could be valued at up to $1 billion over a ten-year period, supporting Eve’s substantial order backlog of 2,800 aircraft.

The partnership marks a strategic pivot from vertical integration to a “best-of-breed” supply chain approach. By selecting BETA’s proven propulsion technology for forward flight, Eve aims to de-risk its certification timeline while retaining Nidec Aerospace as the supplier for its vertical lift motors.

Technical Breakdown: The “Lift + Cruise” Architecture

To understand the significance of this supplier selection, it is necessary to examine Eve’s specific aircraft design. The company utilizes a “Lift + Cruise” configuration, which separates the propulsion systems used for hovering from those used for forward flight.

Distinct Propulsion Roles

Under this architecture, the aircraft relies on two distinct motor types:

• Vertical Lift: Eight dedicated propellers provide the necessary thrust for take-off and landing. These components are supplied by Nidec Aerospace, a joint venture between Nidec and Embraer.
• Forward Cruise: A single pusher propeller located at the rear of the aircraft drives it forward. This is the specific component BETA Technologies will now supply.

By separating these functions, Eve can optimize each motor for its specific phase of flight, high torque for the lift motors and high efficiency for the cruise motor.

BETA’s Motor Specifications

According to technical details surrounding the deal, Eve is expected to utilize BETA’s proprietary motor technology, likely the H500A series currently used in BETA’s own ALIA aircraft. Key specifications highlighted in industry analysis include:

• Redundancy: The motor features a dual-redundant internal rotor design, effectively operating as “two motors in one” to ensure continued operation even if one electrical channel fails.
• Power Output: The system offers a maximum power of approximately 427 kW and continuous power of roughly 300 kW.
• Efficiency: The motors boast an energy conversion efficiency of approximately 98%.

“These motors have been validated through thousands of flight hours on BETA’s own ALIA test aircraft, reducing the technical risk for Eve.”

Strategic Implications for the eVTOL Market

This agreement highlights a growing trend of cooperation between companies that might otherwise be viewed as competitors. Both Eve and BETA are developing their own electric aircraft, yet this deal positions BETA as a Tier 1 supplier to other Original Equipment Manufacturers (OEMs).

The “Buy” Over “Build” Advantage

For Eve, the decision to source a critical propulsion component externally rather than developing it in-house offers clear strategic advantages. It allows the company to leverage BETA’s existing flight heritage, BETA has flown its motors extensively across the U.S., thereby potentially accelerating Eve’s entry into service, targeted for 2026.

Supply Chain Maturity

With this selection, Eve has secured top-tier suppliers for the majority of its critical systems. The supply chain now includes:

• Cruise Motor: BETA Technologies
• Lift Motors: Nidec Aerospace
• Avionics: Garmin
• Batteries: BAE Systems
• Thermal Management: Intergalactic

The Era of “Frenemies” in Flight

We view this partnership as a maturing moment for the Advanced Air Mobility (AAM) sector. In the early days of the industry, many startups attempted to vertically integrate every component, from batteries to motors to airframes. Eve’s decision to purchase a motor from BETA, technically a competitor in the airframe space, signals that the industry is prioritizing certification speed and safety over proprietary exclusivity.

Furthermore, this deal validates BETA Technologies’ dual business model. By selling their propulsion tech to other OEMs, BETA diversifies its revenue streams beyond just operating its own ALIA aircraft. For investors, this reduces the “winner-take-all” risk often associated with new technology markets.

Frequently Asked Questions

What is the value of the deal between Eve and BETA?

Reports estimate the agreement could be worth up to $1 billion over the course of 10 years, covering both prototype and serial production phases.

Does this mean Eve is stopping its own motor development?

Eve is retaining Nidec Aerospace for its vertical lift motors. The agreement with BETA is specifically for the pusher motor used in forward cruise flight, allowing Eve to utilize off-the-shelf, proven technology for that specific function.

When is Eve expected to enter service?

Eve Air Mobility is currently targeting an entry into service (EIS) date of 2026.
