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.
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.
