Motor Overview
The Dayton 6K630 is a general-purpose, single-phase motor rated at 1-1/2 HP and 3450 rpm. It uses a capacitor-start design and fits a 143T frame with a rigid base. The open drip-proof enclosure suits indoor fan and blower applications where ambient temperatures stay at or below 40 degrees C.
Compatibility Check
Verify that your supply voltage matches 115 V or 208-230 V AC at 60 Hz. The motor draws 18.6 A at the low voltage and 9.8 to 9.3 A at the higher voltages and is usable at 208 V. Confirm the shaft rotation requirement; this unit runs clockwise or counter-clockwise and mounts at any angle. No thermal protection is built in, so external overload provision is required.
Upgrade Context
This motor replaces a failed unit of the same frame, horsepower, speed and enclosure type. The 1.15 service factor provides a modest margin for occasional load peaks. It is not suited for applications needing sealed bearings, integrated thermal switches or a totally enclosed enclosure. Buyers needing variable speed or lower noise should consider alternative designs.

Questions about this item
What is included with the Dayton 6K630 motor and what must be purchased separately?
The motor ships as a complete unit with a rigid base and open drip-proof enclosure. A capacitor, wiring, overload protection and any pulleys or couplings are not included and must be sourced separately.
Which voltage setting should I choose for the 115/208-230 V motor?
Wire the motor for 115 V if your supply is 115 V; wire it for 208-230 V if your supply is 208 V or 230 V. The nameplate shows full-load amps of 18.6 A at 115 V and 9.8-9.3 A at 208-230 V.
What does the 3450 rpm rating mean once the motor is installed?
At 60 Hz the motor runs at a nameplate speed of 3450 rpm under full load. With a 1.15 service factor it can handle brief overloads, and the continuous duty rating means it can operate non-stop at 40 °C ambient.
