Dayton 5K671 General Purpose Motor
The Dayton 5K671 is a single-phase, split-phase motor designed for general HVAC applications. It operates at 115V AC with a 1.35 service factor and offers two-speed performance for flexible airflow control. The cradle base mounting and steel frame provide a durable foundation for continuous duty cycles in compatible equipment.
Open Drip-Proof Enclosure Limits
The open drip-proof enclosure permits ventilation while guarding against vertically falling liquids. It is not sealed against dust, moisture spray or direct water exposure, so the motor must be installed in a protected indoor location. Ambient temperatures must not exceed 40 degrees C to maintain the Class B insulation rating and continuous duty rating.
Dual-Speed Nameplate RPM
The motor delivers 1,725 RPM at 1/4 hp and 1,140 RPM at 1/8 hp, with corresponding full-load currents of 4.6 A and 4.3 A. The 48Z frame and flat shaft design must match the driven component exactly. Buyers who need a different speed range, horsepower rating or shaft configuration should select another model.

Questions about this item
Should I use the 1/4 HP or 1/8 HP setting for my application?
The motor delivers 1/4 HP at 1725 RPM and 1/8 HP at 1140 RPM. Choose the higher speed for greater output or the lower speed for quieter, reduced-power operation.
What do the two nameplate RPM values mean for actual shaft speed?
The motor runs at 1725 RPM on the high-speed winding and 1140 RPM on the low-speed winding under full load at 60 Hz.
How does the 115 V AC single-phase supply limit the motor's performance?
At 115 V the motor draws 4.6 A at high speed and 4.3 A at low speed, with a 1.35 service factor allowing temporary overload within the 40 °C ambient rating.
