If
your concern is recovering wheel speed, you want your CIM to be spinning at roughly half the free speed at your setpoint. That way, when the speed drops due to a frisbee passing through, you are near the max power point on the operating curve. Also, the more command headroom you have at your setpoint, the faster the recovery.
For a more thorough answer, please answer these questions:
- what motor controller(s) are you using for the shooter?
- what motors(s)
- what is the total gear ratio from motor(s) to wheel(s)
- wheel(s) diameter
- what is your setpoint operating speed(s)
- what is the current draw or voltage at those operating speed(s)
- what speed sensor are you using?
- how are you decoding the speed sensor signal?
- what's your speed control method (PID, bang-bang, TBH, etc)
