Dayton HVAC Shaded-Pole Motor

The Dayton 71633696M is a single-phase shaded-pole HVAC motor rated at 1/40 hp and 1550 rpm on 115 V AC. It draws 1.0 A at full load and delivers 19 W of continuous output from a 3.3 frame steel housing with an open air-over enclosure.

Suitable Replacements and Voltage Limits

This motor suits technicians replacing a failed 115 V shaded-pole unit in residential or light-commercial air-handling equipment where a stud-mounted, clockwise-shaft rotation is specified. It is not usable at 200 V or 208 V, so installers working on dual-voltage systems must select a different motor.

Critical Voltage Compatibility

The single specification that decides fitment is the 115 V AC, 60 Hz nameplate rating combined with the explicit statement that the motor is not usable at 200 V or 208 V. Match this voltage exactly or the motor will not operate.

Questions about this item

Will the 19 W output handle continuous duty without overheating?

The motor is rated for continuous duty with Class B insulation and automatic thermal protection, designed for a maximum ambient temperature of 40 °C.

How much noise and heat does the open air-over enclosure produce at 1550 rpm?

The open air-over design relies on airflow from the driven fan for cooling; the motor itself runs at 1.0 A full-load current and 19 W output, so heat and noise are low but depend on the fan installation.

What mounting hardware must I already have for the 3.3 frame stud mount?

The motor uses a stud mounting pattern on a steel frame; you will need matching stud holes or a bracket that accepts the 3.3 frame dimensions.
