Technical corrections
1. I discuss changing the bearing to allow higher speeds of the test motor. However, the rotor of your braking motor is designed/balanced for a specific rpm. It might vibrate or even self destruct if spun at higher speeds. My motor has survived several test at 21k for an up coming video, but that certainly won't apply to all motors used for this.
