Dayton 6K405 Pedestal Fan Motor
The Dayton 6K405 is a single-phase split-phase pedestal fan motor rated at 1/2 hp. It runs on 115V AC at 60 Hz with a nameplate speed of 1,725 RPM and draws 7.9 A at full load. The motor uses a 48YZ frame, Class B insulation and continuous duty cycle. Automatic thermal protection and an open air-over enclosure suit HVAC air-handling installations.
Suits direct-drive pedestal fans needing
Installers replacing a 1/2 hp, 115 V, single-speed unit with a 5/8 in. shaft and 2 in. shaft length will find the mounting and electrical specs match. Buyers who need a different voltage, higher horsepower, multi-speed operation or a vertical mounting orientation should look at something else because this motor is fixed at 115 V, 1/2 hp, one speed and horizontal mount only.
Mounts horizontally on standard 48YZ bolt patterns
The 5/8 in. diameter shaft extends 2 in. for direct coupling or pulley fitment. Wiring connects to 115 V single-phase supply; rotation is reversible between CW and CCW. Common issues include wiring the motor for the wrong rotation direction, insufficient airflow through the open air-over enclosure causing thermal trips at 40 °C ambient, and using undersized conductors for the 7.9 A full-load current.

Questions about this item
What voltage supply and circuit capacity are needed for the 115 V AC, 7.9 A full-load motor?
The motor runs on 115 V AC single-phase power and draws 7.9 A at full load, so the branch circuit and breaker must be rated for at least that current.
Will the 48YZ frame and 5/8 in. shaft fit the mounting pattern and fan hub on my existing pedestal fan?
The motor uses a standard 48YZ frame with a 2 in. long, 5/8 in. diameter shaft, matching many common pedestal-fan mounts, but verify the bolt circle and hub bore before installing.
How can I confirm the motor is running at the correct 1,725 RPM after installation?
With power applied, measure shaft speed using a contact or laser tachometer; it should read approximately 1,725 RPM under load at 60 Hz.
