BETA NM Flown

Applications

Lift, push, and hybrid custom configurations power
Urban Air Mobility, VTOL, and CTOL applications.

High Torque This quad-redundant operations-expanding vehicle mover is 684 millimeters in diameter, providing high torque for high power-density operations and enabling aircraft to take off and land vertically in every element.

High Efficiency

This kilowatt-sipping, high-efficiency, sensorless-controlled motor, 566 millimeters in diameter, gives aircraft climb and range flexibility thanks to its dual-redundant internal rotor with an integrated hollow shaft.

All Conditions Every BETA propulsion system is designed, validated, conformed and customized to the operational requirements of our customers and their mission.

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.
