In this video I try to explain why is coreless motor better option for model train locomotive than iron core motor. Iron core motor shown in this video has extremely strong cogging effect, so better iron core motors of course exist. I chose this motor because it shows very clearly disadvantage of iron core motors when motor control (DCC) is considered.
Locomotive is Intermountain Cab Forward (also shown in my earlier video). Iron core motor is factory installed, later I replaced it with coreless motor as shown in this video.
Coreless motor with single shaft shown in this video can be bought here:

The same motor, but with dual shaft is recently also available:

By the way, test with vertical wheelset is excellent if you want to check easily if there is any jerkiness during slow speed running. If there is any, it will reveal it without mercy!
