Product Identity
The Dayton 4YU26 is a permanent-split-capacitor HVAC control motor rated at 1 HP and 1140 RPM. It operates on single-phase 115/230 V AC power and uses a 48Z frame with rigid base mounting.
Installation Checks
Confirm your system supplies 115 V or 230 V at 60 Hz and can deliver 11.4 A or 5.7 A respectively. Verify the shaft rotates freely in both directions and that the ambient temperature will not exceed 40 °C. Ensure the open air-over enclosure suits your ventilation path and that 200 V or 208 V operation is not required.
Suitability
This motor suits direct-drive blower replacements needing continuous duty and auto thermal protection. It is not for applications requiring multiple speeds, 200 V or 208 V compatibility, or a different frame size. Builders needing variable-speed control or a totally enclosed design should look elsewhere.

Questions about this item
Does the Dayton 4YU26 motor ship with a capacitor or mounting hardware, or do I need to buy those separately?
The motor is a permanent split capacitor design and includes a rigid base for mounting; a compatible run capacitor matched to the 1 HP 115/230 V rating must be sourced separately.
The listing shows 115/230 V — can this motor be wired for 208 V or 200 V service?
No, the specifications state it is not usable at 208 V or 200 V; it is rated only for 115 V or 230 V single-phase 60 Hz supply.
With a nameplate speed of 1140 RPM and 1 HP, what full-load current should I expect on a 230 V circuit?
At 230 V the motor draws 5.7 A full-load amps, and at 115 V it draws 11.4 A, with a 1.0 service factor and Class B insulation for continuous duty.
