This is a BRAND NEW Carrier/Bryant/Payne Squirrel Cage or Blower Wheel . The part # is LA22LA017. It's 11 1/8" in diameter and 6" tall with a 1/2" bore. If the wheel is sitting with the set screw up (as seen in the picture) rotation would be counter clockwise. Thanks for looking and good luck!
An electric motor converts electrical energy into mechanical energy. In an HVAC system, motors typically turn the air conditioning fan blade and the furnace blower motor. Newer high efficient motors, such as X13 and ECM motors, have "end caps" that control the motor speeds. These can be removed and replaced separately.
