@cnwdon posted:Any comments on how many minutes or hours of running in motors of this vintage need to get as smooth as they are going to get? I don’t have much experience with them.
@cnwdon posted:After 45 min+ running in, in each direction on rollers, smoothed out. Then pulled ore drag as intended and the only problem is the lack of cruise control, not available for AC motors, so that's the way it is.
Electric Railroad (ERR) makes a unit called the AC Commander that can be installed with TMCC AC motored engines (i.e., those with Pullmor motors), which will make them run smoother, and will provide additional speed steps for significantly slower speeds. Next best thing to cruise control for AC engines. Running TMCC engines using Legacy also improves running characteristics of these engines.
Regarding breaking in Pullmor motors, they typically continue to smooth out with age. You indicate you have rollers. You could probably run them repeatedly for hours (with occasional breaks for cool-downs) and it would continue to break them in. Older Pullmors with years of operation run very smoothly.
