Ceiling Fan Motor for Home Airflow
The Dayton 5RHT8 is a single-phase permanent split capacitor motor built for ceiling fan and blower applications. It delivers a horsepower range of 1/5 to 3/4 HP at a nameplate speed of 1075 rpm. The unit operates on 115V AC power with a full-load current draw between 8.7 and 2.4 amps. It suits homeowners replacing an existing fan motor or installing new overhead airflow equipment.
Electrical and Thermal Operating Limits
The motor runs on standard 60 Hz household current and carries a 1.0 service factor for continuous duty cycles. Automatic thermal protection and Class B insulation guard against overheating up to a maximum ambient temperature of 60 degrees Celsius. The open air-over enclosure relies on the fan blades to move cooling air across the windings. These specifications define the safe electrical and thermal envelope for daily operation.
Flexible Mounting and Wiring for Installation
A 48YZ frame with hole and stud mounting allows all-angle positioning to fit various ceiling fan housings. The 5-inch shaft length and 36-inch lead wires provide reach for standard blade assemblies and junction box connections. Reversible CW/CCW shaft rotation lets the installer set airflow direction without rewiring the motor internals. This mechanical flexibility simplifies retrofit and new-installation work alike.

Questions about this item
Should I choose the 1/5 HP or 3/4 HP setting for my application?
The motor delivers a range from 1/5 HP up to 3/4 HP, with full-load current dropping from 8.7 A at the lower end to 2.4 A at the higher end; match the tap to the airflow and static-pressure requirements of your blower.
What does the 1075 rpm nameplate speed mean once the motor is installed?
At 60 Hz the shaft turns at 1075 rpm under rated load; actual speed will vary slightly with the selected horsepower tap and the connected fan load.
How does the 115 V single-phase supply limit the motor in practice?
The motor draws 8.7 A at 1/5 HP and 2.4 A at 3/4 HP on a 115 V AC circuit, so branch-circuit wiring and breaker must be sized for the highest anticipated current.
