It has a standard size shaft. Compatible with Coleman, Luxaire, York, amd Evcon hvac equipment. It's 1/3hp and has a rotation speed of 1,100 rpm.
I run it (my electric furnace)off a 100amp and it works as intended. Product has never been used and has no signs of heavy wear. I don't know much about hvac equipment, I just ordered incorrectly and can't return it. Feel free to message me with any questions.
