The Bosch 8733953243 is an electronically commutated (ECM) motor that powers the blower inside an air handler, keeping conditioned air moving through the system while pulling less power than a conventional PSC motor at similar output. It runs on 208 to 230VAC single-phase power at 50/60Hz, produces 3/4 horsepower, draws 4.5 amps, and spins at 1050 RPM under continuous duty. The long steel shaft extending from one end of the housing gives an installer room to seat a blower wheel or fan blade at the exact depth the air handler calls for, which makes it easier to match the motor to different assemblies. Cast aluminum end shields close off the cylindrical body and protect the windings inside, and the motor uses the airflow it generates to carry away its own heat, so it holds to its Class B insulation rating during normal operation. A factory-wired lead harness with a keyed plug ties it into the unit, letting the motor go in as a direct working replacement for air handler service.
