As udarrel says, make sure you don't exceed the rated amps for the
motor. I have a few of these furnace blower "fans". You need a
bit of framework to hang on to the squirrel cage anyway, I use a
piece of peg board across the non-motor side of the housing. This
is usually enough to get the amps down to a decent level.
