I am having a major problem with one of my motors that was being used on my Vex Elevation robot…
-motor starts fast and gradually over a 20+ second time period slows down drastically
-motor heats up during this process stated above
-interior motor gears were replaced and nothing changed.
-Currently the green and black (front and back cover) of the motor and the gears have been removed. This rules out the possibility that the motor is being stopped by an outside external force
-the motor was not put under any heavey stress loads. The gearing that it was put under dealt with high torque which it should have been easily able to withstand
-these symptoms occur no matter what motor port is used
-batteries have been switched and have been ruled out as a cause of this problem
-extra: code running at the moment is the default code
-after a bit of cooldown the motor is able to run at full speed again but immediately starts slowing down
Does this mean that my motor has lived its glorious life and needs to be replaced? Is there a possibility of you guys taking a look at it (shipped to you) and repairing it without having to pay the full price for a new motor?
If you have any ideas that would be great. The VRC competition is only a few days away and this definitely is a problem that I hope you guys can help me resolve as soon as possible.
