"Universal" Motors: AC Vs. DC

StrummerOGR Forum Member SUPPORTING MEMBER

I'm sure this has been discussed before, but since every site I've looked at seems to have a different answer, I thought I'd ask here.

Does the universal motor in an American Flyer engine actually run any different or better on DC?

I have a large and very nice Heathkit power pack, which runs my DC trains wonderfully. However, although it can run my AF engines very well, it does show a tendency to trip the "overload" circuit when powering one of these AC/DC locos. These same engines run fine with my MRC AC pack, with no signs of "overloading". Is this due to amperage, or what is the cause?

Any thoughts or experiences are most welcome. Thanks.
