You think the DRO turning off the motor is faster than a switch turning off the motor and hitting the brakes?

In working on the Eclipse jet engine [Pratt Whitney] starter generator controller, we had to calculate the angular momentum of a flywheel that would be the same load as starting the engine. We built a test fixture and put a motorcycle disc brake on the flywheel. We put strain gauges with radio transmitters to measure torque. We needed the brake... It took too long waiting for the wheel to stop after we quit applying power to the motor.
