glnc222 wrote:Did you have to pull the motor out of a gear train? Maybe should not run with all the gears under USB without disassembly. The speed control though, might solve the heating problem. But then a fast speed is needed to get enough smoothing... You can use 12v portable (or not) car batteries, too.
With the main load of the vacuum off, battery should give a lot more run time on USB. I think motor commands are disabled under USB when the charger is attached (so you don't trip over the cable -- product liability dragons; and new models don't have the charging cable anymore).
Thanks for cross-reference posting.

That is not a normal condition and a break-in run is not necessary with new robotic vacuums. aziesemer2 was just lucky that the motor windings didn't short out and burn up the motor from the high amount of current utilized to drive the wheel.
