Dayton 5RHT9 Blower Motor Overview

The Dayton 5RHT9 is a single-phase permanent split capacitor blower motor designed for HVAC and air-moving equipment. It delivers a horsepower range from 1/5 to 3/4 HP at a nameplate speed of 1075 RPM. The motor operates on 208-230V AC at 60 Hz and fits a 48YZ frame. It is built for continuous duty in ambient temperatures up to 60 Degrees C.

Electrical and Interface Limits

The motor draws between 4.1 and 1.7 full-load amps depending on the load point across its voltage range. Its open air-over enclosure requires airflow from the driven fan for proper cooling. The unit provides four selectable speeds and reversible CW/CCW rotation. Thermal protection is automatic and the insulation rating is Class B with a 1.0 service factor.

Pre-Installation Checks

Verify that your application can supply 208-230V single-phase power at 60 Hz and accommodate a 48YZ frame with hole-and-stud mounting. Confirm the driven shaft length of 6 in matches your blower wheel or coupling. Ensure the installation environment stays within the 60 Degrees C maximum ambient rating and that airflow will reach the open enclosure for cooling.

Questions about this item

Should I pick the 1/5 hp or 3/4 hp setting for my application?

The motor delivers 1/5 hp at the lowest speed and 3/4 hp at the highest of its four speed taps; choose the tap that matches the airflow and static pressure your system requires.

What does the 1075 rpm rating mean once the motor is installed?

1075 rpm is the nameplate speed at full load on the highest tap; actual speed will vary slightly with voltage, load and the selected speed tap.

How does the 208-230V single-phase supply limit the motor in practice?

The motor draws 4.1 A at 208 V and 1.7 A at 230 V on the highest tap; circuit and wiring must be sized for the higher current at the lower voltage.
