Motor type and rating
The Dayton 4HZ68BG is a direct-drive blower motor built for HVAC control applications. It uses a permanent split capacitor design rated at 1/6 horsepower with a nameplate speed of 850 RPM.
Suitable installations and limits
This single-speed motor runs on 115V AC at 60 Hz and draws 2.4 A at full load, making it a fit for residential or light-commercial air-handling units that require a 48Y frame. It is not suited for variable-speed drives, three-phase supplies, or installations where the ambient temperature exceeds 40 degrees C.
Continuous duty performance
The open air-over enclosure and Class B insulation support continuous duty at the rated 1.0 service factor. Auto thermal protection resets after an over-temperature event, and the all-angle ring-stud mounting keeps airflow consistent during sustained operation.

Questions about this item
What voltage supply and amperage must the installation circuit provide for this 115 V motor?
The motor runs on 115 V AC at 60 Hz and draws 2.4 A at full load, so the circuit must supply 115 V and be rated for at least 2.4 A continuous.
Will the open air-over enclosure and CCWSE shaft rotation match the blower housing I am keeping?
The motor uses an open air-over enclosure and the shaft rotates counter-clockwise when viewed from the shaft end; verify the existing housing accepts that airflow path and rotation direction.
How can I confirm the motor is running at its rated 850 RPM after wiring it?
With power applied, measure shaft speed with a tachometer; a steady reading at or near 850 RPM shows the permanent split capacitor motor is operating at nameplate speed.
