Many furnace blowers are engineered to work within specific static
When they are operated outside the ductwork, some blowers will overload
unless you rig-up some static resistance.
Use an amprobe to see if it is drawing too many amps; some blowers will
bog down, it all depends on how they were engineered to operate.

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.

If you can figure out which leads are the 120v pair it should work
fine. Black and white are logical but that may be too easy. Is there a
wiring diagram on the motor plate or inside the end bell? Otherwise
try googling every number and name you see.
