So I was putting some final adjustments on my robot today, when I noticed some of the motors on my intake would not run not matter what I did. They ran fine for a few seconds, then shut off. I changed ports and checked the motor controllers and all was fine. The strange part was, when I would turn them by hand, it was near impossible. I wasn’t sure why, because there was no stress on them I assumed they didn’t break, so I re-programmed them and I still had the same issue. So then, I unplugged a wire that ran to my intake, and all of a sudden the motors spun freely, and ran fine. The strangest part was that they were still bogged down after the Cortex had been turned off and un-plugged, but please note that they do this only when that wire is plugged into the cortex. What I am asking is, why does this specific motor shut off and bog down other motors when plugged into the cortex, and how can I fix this?! (I have tried this motor in multiple ports, and it just shuts off two different motors.)
Most DC Motors, when turned, become a DC Generator…
If the Output of the Cortex to Control the Motor is Fused/Shorted, turning the Motor by hand would be trying to Push electrons through the Short, and I believe would cause the Issue you are describing…
After disconnecting the Motor from the Cortex and finding that it turns freely, if you plug it back into the Cortex, WHILE NOT BEING POWER BACK UP, and try to turn it, does it Spin Freely, or is it Near Impossible again??
After removing the Motor from the Cortex, if you Short Together the two Wires of the Motor, and try to Turn it, is it Near Impossible to Turn??
I did figure out what the problem with the motor was that was causing other ports to freeze up. I switched out the motor controller I had on and it worked fine; it didn’t freeze up and it didn’t bog down the other motors. Thank you for your help though!
To answer your questions:
A.) After disconnecting the Motor from the Cortex and finding that it turns freely, if you plug it back into the Cortex, WHILE NOT BEING POWER BACK UP, and try to turn it, does it Spin Freely, or is it Near Impossible again??
It is near Impossible again. But no, I didn’t try shorting the wires together.
I did not realize you were using the Motor Controller 29 … Sounds Like it is “fried”…
Oh Okay, sorry for not being a little more specific! Thanks for the help though!
Your Welcome… Good Luck at your Competition…
