I had a motor from a vacuum cleaner that was AC/DC.  It worked great when 
the TC was turned off, you could vary the speed using a dimmer switch or a 
variac.  But when the TC was turned on, interference stopped it from 
turning.  Some good shielding might have fixed this, but a simple grounded 
aluminum foil shield did nothing.  Thanks.
