I won't pretend to know the answer from experience or a swell list of academic credentials. But I'd say yes without worry to using a transformer and bridge rectifier, given that all of them are rated for that much current. A large electolytic capacitor might help smooth the current more, but I don't think that's important with motors. (I hope an electronics guy pipes in, because this is a great idea.)
In fact I wish I'd thought of this.
I have hooked mine up to a car battery. Runs quite well.
