Motor Type and Target Use
This capacitor-start motor delivers 3/4 hp at 1725 RPM for single-phase HVAC fan and blower applications. It suits technicians who need a direct replacement in equipment wired for 115/208-230V AC supplies. The open drip-proof enclosure and Class B insulation fit standard indoor mechanical rooms. Buyers who require a totally enclosed or wash-down rated enclosure will need a different motor design.
Installation Requirements and Flexibility
The 56 frame with cradle base mounting aligns with common HVAC motor brackets, while the 1.25 service factor provides headroom for continuous duty at 40 Degrees C ambient. Auto thermal protection reduces nuisance tripping during extended runs. The motor operates on 115V or 208-230V but is not usable at 200V, so installers must verify the supply voltage before wiring. Shaft rotation is reversible to match blower direction.
Sustained Load Behaviour
Continuous duty rating and 10.6 A full-load amps at nameplate voltage indicate stable current draw during long heating or cooling cycles. The 1.25 service factor absorbs temporary overloads without tripping the automatic thermal protector. At 60 Hz the motor maintains 1725 RPM under load, delivering consistent airflow for ducted systems. Performance drops if the supply falls below 208V, so voltage stability matters for sustained operation.

Questions about this item
How long can the motor run continuously at 40 °C ambient before the 1.25 service factor becomes the limiting factor?
The motor is rated for continuous duty at up to 40 °C ambient with a 1.25 service factor, so sustained full-load operation within those limits is its design intent.
What is the full-load current and enclosure type that determine heat and noise during all-day operation?
It draws 10.6 A at full load and uses an open drip-proof enclosure, which moves air directly through the windings for cooling but also transmits more mechanical noise than a totally enclosed design.
Which voltage must the site supply and what mounting does the 56 frame require?
The nameplate lists 115/208-230 V AC, 60 Hz, usable at 208 V but not at 200 V, and the 56 frame mounts on a cradle base.
