Dayton 3K344 2 HP General Purpose Motor

The Dayton 3K344 is a single-phase capacitor-start/run motor rated at 2 horsepower and 3450 RPM. It fits a 145T frame and mounts on a rigid closed base for stationary equipment. Voltage is selectable at 115 or 208-230 V AC for workshop or light-industrial machinery.

Voltage and Frame Compatibility

The motor runs on 115 V drawing 19.5 A or on 208-230 V drawing 10.8-9.7 A at 60 Hz. The 145T frame and rigid base mounting must match the driven equipment. Usable at 208 V, it suits installations where that supply is standard.

Continuous Duty Within Thermal Limits

Class B insulation and a 1.0 service factor support continuous operation up to 40 °C ambient. Totally enclosed fan-cooled construction protects windings in dusty environments. No thermal protection is fitted, so overload monitoring must be provided externally. The motor is restricted from sale in California.

Questions about this item

How does the 3450 RPM nameplate speed translate when the motor is loaded in a fan?

At full load the motor runs at its rated 3450 RPM; the 1.0 service factor means no extra overload margin, so the speed will drop only if the driven load exceeds 2 hp.

What does the 115/208-230 V dual-voltage rating mean for everyday wiring?

The motor can be connected to either 115 V or 208-230 V supplies; at 115 V it draws 19.5 A full-load, while at 208-230 V it draws 10.8-9.7 A.

What does the 145T frame designation tell me about mounting dimensions?

The 145T frame defines standard NEMA shaft height, shaft diameter and bolt-hole spacing for rigid-base mounting on a closed-base housing.
