Product Identity
The Dayton 194174.00 is a three-phase general purpose motor rated at 1 HP with a 143T frame. It operates on 230/460V AC at 60 Hz and suits industrial HVAC control applications requiring continuous duty operation.
Voltage and Phase Constraints
This motor requires a three-phase power supply at either 230V or 460V and draws 2.7 or 1.4 amps at full load respectively. Single-phase supplies cannot operate it and the fixed 1745 RPM nameplate speed suits constant-speed loads only.
Installation Checks
Verify your system provides three-phase power at the correct voltage and that the 143T frame with rigid base mounting matches the existing footprint. Confirm the 40 degrees C maximum ambient temperature rating suits the operating environment and that CW/CCW rotation direction is acceptable.

Questions about this item
What does the 1 HP rating mean for actual HVAC performance?
The motor delivers 1 horsepower at 1745 RPM with 85.5 percent nominal efficiency, providing continuous-duty torque for fan or blower loads in HVAC systems.
How does the 230/460V three-phase input affect installation?
The dual-voltage design accepts 230 V or 460 V three-phase 60 Hz supply; full-load current is 2.7 A at 230 V and 1.4 A at 460 V, so wire and breaker sizing follow the chosen voltage.
What does the 143T frame and rigid base mounting imply for replacement?
The NEMA 143T frame with cast-iron rigid base matches standard foot-print and shaft-height dimensions, allowing direct bolt-in replacement for other 143T motors.
