Propulsion

We make world-class propulsion systems, and strap airplanes to them.

Applications

Lift, push, and hybrid custom configurations power
Urban Air Mobility, VTOL, and CTOL applications.
High Torque 600 millimeters in diameter, BETA’s quad-redundant, high-torque, high power density operations-expanding vehicle mover enables aircraft to take off and land vertically in every element.
High Efficiency

500 millimeters in diameter, BETA’s dual-redundant, integrated hollow-shaft internal-rotor, high-efficiency, sensorless controlled, kilowatt-sipping motor provides aircraft with climb and range flexibility.
All Conditions Every BETA propulsion system is designed, validated, conformed and customized to the operational requirements of our customers and their mission.

Designed, produced and sold by BETA Technologies, our motors power vehicles across all platforms and propulsion needs.

4x Redundancy BETA’s V600A lift motor features 4x redundancy. The H500A features 2x redundancy

Climb On Kilowatts

Designed to meet the operating needs of emergency medical tissue transport carriers, the H500A pusher and V600A lift also meet the challenge of decarbonizing air transportation. All-electric means zero fossil fuels. We love horsepower — we just love kilowatts more.

Our electric propulsion systems set the standard for state-of-the-art electric motor technology, innovation, advanced materials, and production process.

Validation

We fly what we build. Safety, reliability and performance are the byproducts of BETA’s in-house validation and piloted flight test.

Endurance Testing

Our remotely controlled motor endurance stands, driven by 5.3MW of power and 24/7 live feed, let us use higher thrust loads that surpass the most rigorous customer requirements and mimic operations exposed to rain, sleet, snow, flying pigs, or boring sunshine.

Dynamic Power Analysis

Dynos — with up to 4800 Nm of torque and 3500 rpm are remote controlled, operate with regenerative power, and are under 24/7 live camera feed. All of our dynos are equipped with instrumentation such as HBM power analyzers, accelerometers, temperature sensors, torque cells, rpm meters, high speed data acquisition up to 10 kHz, and Speedgoat and Simulink controls.

We manipulate load side motors to mimic the operational behaviors of our customers' use cases, ensuring that when customers take delivery, the motor's hardest working days are behind them.

Sweet Silence

Electromagnetic interference (EMI) is unwanted noise or interference in an electrical path or circuit caused by an outside source. Our semi-anechoic and reverberation EMI chambers support DO-160G compliance testing, including high-intensity radiated field (HIRF) and lightning. The only signal these motors hear is the one the operator sends.

Support is One Click Away

Electric propulsion isn't new, and neither is expecting high quality aftermarket support. Our sustainment and maintainer expertise comes from decades of customer service and support. We've put our expertise in motors at your fingertips, bringing aerospace-industry standards in safety and reliability to modern day accessibility.
