What about the motor, gears, axles? Are they lubed? Is there something binding in the powertrain?My atlas trolley ( few years old)is taking a dump. Only runs slow at full speed. Its all electronics inside. I guess the speed controller is shot. Anyone else with this problem?
A conventional powertrain with likely a DC can motor and rectifier. Not many pieces to the puzzle.
That's likely an electronic version of an E-unit for switching direction. If you don't need direction control, a simple bridge rectifier will convert AC track voltage to DC for the can motor. Then the transformer's throttle is the speed control.I opened it up. Has a large speed control board with a ton of components on it. Not simple at all. Thinking about putting in a bluerail board. Any of you guys tried that?
Are you sure (not aware of your skills)?Its the motor, fried. Cant seem to find one on net. Double worm drive. p/n 727a12v0 s7609a11 (A)
What are my replacement options?
Try a search of hobby robot motors retailers. Here's one. They'll have an assortment of small DC can motors you can buy in single units.pulled the motor and its seized, hence the current draw. Need a source for Chinese motors.
