Centripetal Acceleration is equal to tangential velocity squared divided by radius.
We calculated that for the 5 inch diameter motor armature at 100 RPM the centripetal acceleration would be about 7 m/s^2 or 0.7 g's. We calibrated the accelerometer and 8x8 LED matrix to light almost all the LEDS at 1 gravity so at about 100 RPM there should be about 5 and a half rows of LEDS lit up.
So the idea is at some point in the future to integrate just the accelerometer into the motor control that is on the bottom of the armature and have it regulate the motor so that it could sense when the motor was going out of phase and make corrections or at least stop and restart the motor from a slow speed.
Stay tuned:)
