Our biggest problem in building our robot has been procrastination... As such, the robot was built yesterday, in time to discover that FP motors like to overheat. Our "leadership" called me to see if I as a programmer could slow them down to avoid a bonfire. I'm not too knowledgeable with the motors and such, but as I have read and understand it, slowing down the FPs would only cause more overheating, but maybe I'm wrong. If anyone has any advice, I'd love to see it. If we should change to a different motor, suggestions as to which ones would be greatly appreciated, as any other advice.
Thanks in advance. |
If your motors are overheating the answer is NOT to slow them down. It is to speed them up! If a motor is getting too hot then it is turning too slowly. FPs of all years like to run around 15,000 rpm. If you are not running that fast then too much energy is being turned into heat.
More gear reduction is the proper answer. Getting it is the problem.
BTW we managed to blow up an FP tranny early this morning. Apparently our arm blew through an electronic stop and hit the hard stop. Fragments of the output stage wound up all over. But the motor did not fry. At least our gear ratios are right!
