Three-Phase HVAC Motor for Fan
The Dayton 4YU39 is a three-phase fan and blower motor rated at 1.5 hp and 1725 RPM. It operates on 208-230/460V AC at 60 Hz with a 56H frame and open drip-proof enclosure. Designed for continuous duty in HVAC systems, it suits technicians and facility managers replacing or specifying drive motors for air-handling equipment.
Voltage Compatibility Determines Fit
The motor is usable at 208 V and rated for 208-230/460 V, but it is explicitly not usable at 200 V. Full-load current is 4.8 A at the lower voltages and 2.4 A at 460 V. A service factor of 1.15 and Class B insulation support sustained operation up to a maximum ambient temperature of 40 degrees C.
Rigid-Base Mounting with Reversible Rotation
The rigid-base mounting requires a secure, flat surface and the shaft rotates CW/CCW for flexible drive alignment. No thermal protection is built in, so external overload safeguards must be provided by the installer. The open drip-proof design allows airflow for cooling while resisting dripping liquids.

Questions about this item
How does the 1.5 hp rating translate to actual airflow in my HVAC system?
The motor delivers 1.5 hp at 1,725 RPM continuous duty, driving the fan or blower wheel directly at that speed.
What does the 208-230/460 V three-phase supply mean for my wiring?
It runs on three-phase AC at 208-230 V or 460 V, drawing 4.8 A per phase at the lower voltages and 2.4 A at 460 V.
Will the 56H frame with rigid base bolt onto my existing mounting plate?
The motor uses a NEMA 56H frame with rigid base mounting, matching standard bolt patterns for that frame size.
