Dayton 5K554 General Purpose Motor Split Phase 1/3 HP 1725 RPM 56Z Frame

SKU CH-WBMY-MEFQ1

Two-speed split-phase motor delivers 1/3 hp at 1725 rpm and 1/6 hp at 1140 rpm on 115 V AC with a 56Z frame

  • Split-phase design delivers two-speed operation for flexible airflow
  • 1/3 hp output provides reliable power for general-purpose HVAC tasks
  • Open drip-proof enclosure protects windings while allowing cooling airflow
  • 56Z frame with cradle base fits standard motor mounts
  • Continuous duty rating supports non-stop operation at 40 °C ambient

General-Purpose Split-Phase Motor

The Dayton 5K554 is a single-phase split-phase motor rated at one-third horsepower. It operates on 115 V AC at 60 Hz and carries a 56Z frame designation for standard mounting compatibility.

Open Drip-Proof Enclosure Limits

The open drip-proof design allows airflow for cooling but blocks only vertically falling liquids. It is unsuitable for wet, dusty or outdoor locations where moisture or debris could enter the windings.

Dual-Speed Capacity and Headroom

Two nameplate speeds of 1725 and 1140 RPM give flexibility for belt-drive or direct-drive loads. Continuous duty with a 1.35 service factor handles sustained overloads, while the 40 °C ambient limit defines the thermal boundary.

Questions about this item

Should I pick the 1/3 hp or the 1/6 hp setting for my application?

The motor delivers 1/3 hp at 1725 rpm and 1/6 hp at 1140 rpm; choose the higher speed for greater output or the lower speed for reduced load.

What does 1725 rpm mean when the motor is installed?

At full load the shaft turns at 1725 revolutions per minute, dropping to 1140 rpm when the motor runs at its second speed.

How does the 115 V AC supply affect the current draw?

The motor draws 6.1 amps at 1725 rpm and 3.8 amps at 1140 rpm on a 115 V AC, 60 Hz circuit.
