How are Unmanned Vehicle Propulsion Motors Tested ?


For UAVs, UGVs and USVs, propulsion system performance directly determines mission reliability, endurance and range. While datasheet specifications provide a useful starting point, only testing under realistic operating conditions reveals the true behavior of the complete drive system.

Magtrol’s motor test solutions accurately simulate real operating conditions by applying a precisely controlled mechanical load to the propulsion system. Advanced dynamometer control enables application-specific operating points and load profiles to be reproduced using torque, speed, power or other control modes. At the same time, key mechanical parameters – including torque (N·m), speed (rpm), mechanical output power (W), temperature and additional performance data – are acquired with high accuracy.

Synchronous measurement of the electrical input power [W] and the mechanical output power (W) enables the overall efficiency of the propulsion system to be determined across the entire operating range. Detailed performance and efficiency maps provide engineers with the information needed to compare motors, ESCs, propellers and complete propulsion concepts, identify energy-efficient operating points and validate system integration.

The result is optimized propulsion system performance, reduced power consumption, extended operating time and increased mission range – critical advantages for today’s unmanned vehicles.

You can now get a clear picture of your engine’s performance and behavior based on your platform’s specifications !

Testing applications for UAV, UGV, USV & UUV propulsion systems.

  • UAV propulsion system testing: Simulate propeller load characteristics, aerodynamic drag, acceleration and transient responses during take-off, landing and flight control maneuvers.
  • UGV propulsion system testing: Reproduce rolling resistance, gradient loads, vehicle inertia, start/stop cycles and dynamic driving conditions encountered in real-world operation.
  • USV & UUV propulsion system testing: Replicate propeller and thruster load characteristics, hydrodynamic drag, continuous low-speed/high-torque operation and varying mission profiles.

Advanced dynamometer control accurately reproduces application-specific operating points and load profiles using torque, speed, power or other control modes. Automated test sequences – including acceleration, endurance, efficiency, overload and locked-rotor testing – can be executed repeatably with high precision.

From R&D and design verification to end-of-line production testing, Magtrol systems provide repeatable, automated and fully traceable test procedures for propulsion system characterization, quality assurance and certification.
