Motor type and power

The Dayton 71213779M is a single-phase shaded-pole HVAC motor rated at 1/70 HP and 11 W output. It runs at 3000 RPM on 115 V AC at 60 Hz and draws 0.56 A at full load. The 3.3 frame uses a steel open air-over enclosure with stud mounting and a closed base.

Suitable and unsuitable uses

This motor suits continuous-duty HVAC equipment that requires clockwise shaft rotation viewed from the shaft end and an automatic thermal protector. It is rated for a maximum ambient temperature of 40 °C and carries a service factor of 1 with Class B insulation. Buyers who need operation at 200 V or 208 V, reversible rotation, multiple speeds or a different frame size should look elsewhere.

Compatibility checks

Verify that the application supplies 115 V single-phase power at 60 Hz and can accommodate a 3.3 frame with stud mounting. Confirm the driven load does not exceed 11 W and that the shaft rotates clockwise from the shaft end. Ensure ambient temperature stays at or below 40 °C and that the open air-over enclosure is acceptable for the installation environment.

Questions about this item

Does the 3.3 frame motor need a matching fan wheel and 115 V power supply to run?

Yes — the motor is a 3.3 frame, 115 V AC shaded-pole unit rated at 1/70 hp and 3000 rpm, so it requires a compatible fan wheel and a 115 V, 60 Hz supply.

Can I keep my existing 208 V or 200 V wiring and still use this motor?

No — the specifications state it is not usable at 208 V or 200 V; it is rated for 115 V AC only.

How do I confirm the motor is operating correctly after installation?

Verify the shaft turns clockwise from the shaft end, the unit draws about 0.56 A at full load, and the housing stays below 40 °C ambient during continuous duty.
