General-purpose HVAC motor
The Dayton 30PT54 is a single-phase capacitor-start/run motor rated at 1/3 hp and 1725 RPM. It operates on 115/230V AC at 60 Hz with a 56 frame and cradle-base mounting for horizontal installation. Continuous duty cycle and automatic thermal protection suit always-on HVAC equipment.
Suits direct-drive HVAC duties
This unit fits blowers, fans and pumps that need a 56-frame motor with 1.35 service factor and open drip-proof enclosure. It is not for applications requiring inverter-rated operation, vertical shaft mounting or ambient temperatures above 40 degrees C. Buyers needing variable-speed control should look at alternative designs.
1/3 hp capacity and headroom
At full load the motor draws 3.9 A at 115 V or 1.9 A at 230 V, delivering nameplate speed of 1725 RPM with a 1.35 service factor for short overloads. Insulation class B and 40 C maximum ambient set the thermal limit, while the open enclosure restricts use in wet or dusty environments.

Questions about this item
What voltage supply must I have on site for the 115/230 V AC motor?
The motor is dual-voltage and runs on either 115 V or 230 V single-phase AC at 60 Hz.
Will the 56 frame and cradle base match the mounting holes on my existing HVAC blower?
Yes, the NEMA 56 frame with horizontal cradle base aligns with standard 56-frame mounting patterns used on many blower assemblies.
How can I confirm the motor is delivering its rated output after installation?
Measure full-load current; it should read approximately 3.9 A at 115 V or 1.9 A at 230 V while the shaft turns at 1725 RPM under load.
