Dayton 5K556 Two-Speed HVAC Motor
This Dayton 5K556 is a general-purpose, single-phase split-phase motor built for HVAC control applications. It delivers 1/2 hp at 1725 RPM and 1/4 hp at 1140 RPM from a 230 V AC supply. The 56-frame steel body uses a cradle-base mount and a keyed shaft that rotates in either direction for flexible installation.
Suits direct-drive blowers needing two fixed speeds
Installers wiring a replacement blower or fan that runs on 230 V AC and requires 1725 RPM or 1140 RPM will find the correct frame and shaft here. Buyers who need variable-speed control, thermal overload protection, or a different voltage should look at other motor types.
Dual 1/2 hp and 1/4 hp ratings at 1725/1140 RPM
The nameplate lists two distinct horsepower and speed points: 1/2 hp at 1725 RPM and 1/4 hp at 1140 RPM. Matching both the high and low speed requirements to the driven equipment is the specification that confirms fit.

Questions about this item
Should I choose the 1/2 hp or 1/4 hp setting for my application?
This motor delivers 1/2 hp at 1725 RPM and 1/4 hp at 1140 RPM. Select the higher speed for greater output or the lower speed for reduced power consumption and quieter operation.
What do the two nameplate RPM figures mean once the motor is installed?
The motor runs at 1725 RPM on the high-speed winding and 1140 RPM on the low-speed winding, giving you two distinct operating speeds for the driven equipment.
How does the 230 V AC single-phase supply affect the current draw at each speed?
At 230 V AC the motor draws 3.8 A at 1725 RPM and 2.8 A at 1140 RPM, so circuit protection must accommodate the higher figure.
