Re: Team Update #18
Here's a fun image, generated here. Red line is Ether's theoretical diameter, and the motor load is indeed at max power. Yet the iterations show that a slightly different diameter can squeeze out a bit more due to acceleration being a slightly larger-than-anticipated factor.
Assumes: Battery voltage of 14.4V 6755 RPM Free Speed 0.095 Nm Stall Torque (Extrapolated the stall/free currents based upon a realistic efficiency curve) 2 motors 100% wheel-to-pole efficiency direct-drive minibot straight off the motor 2.3 lb weight Minibot goes exactly 7.5 feet straight up |
