Dayton 5K423 Split-Phase Motor 1/2 HP 1725 RPM 56 Frame

SKU CH-1H42-BAEA5

A 1/2 hp split-phase motor with two-speed 1725/1140 rpm operation, 56 frame, 115 V AC, open drip-proof enclosure and 1.25 service factor

  • 1/2 HP output drives demanding HVAC loads
  • Two-speed 1725/1140 RPM matches variable airflow needs
  • 115 V AC single-phase suits standard building power
  • Open drip-proof enclosure resists moisture and debris
  • 316 stainless steel construction withstands corrosive environments

Motor type and purpose

The Dayton 5K423 is a split-phase, single-phase general-purpose motor rated at 1/2 hp with a 56 frame. It suits HVAC equipment, fans, blowers and light industrial machines that need continuous-duty operation at 115 V AC.

Build integration

The open drip-proof enclosure and cradle base mounting let the unit sit in standard 56-frame cut-outs without a dedicated housing. A keyed shaft and 1.25 service factor absorb start-up torque, while the 316 stainless steel frame resists corrosion in damp plant rooms. The motor is not for builders who need thermal overload protection or a totally enclosed design.

Sustained load behaviour

Continuous duty rating and Class B insulation allow non-stop running at up to 40 °C ambient. Two-speed nameplate ratings of 1725 rpm and 1140 rpm deliver 7.5 A and 5.4 A full-load current respectively, giving stable output over long shifts without thermal trips.

Questions about this item

Does the 1.25 service factor protect the 1/2 HP motor during sustained heavy loads?

The 1.25 service factor allows temporary overloads above the rated 1/2 HP, but continuous operation at full load relies on the Class B insulation and 40°C ambient limit.

How hot does the open drip-proof frame get during all-day continuous duty?

The motor is rated for continuous duty at a maximum ambient temperature of 40°C; the open drip-proof enclosure relies on external airflow to keep the steel frame within Class B insulation limits.

What voltage supply and mounting base does the 56-frame motor need to run?

The motor requires a 115V AC, 60 Hz single-phase supply and mounts on a cradle base with a keyed 56-frame shaft for driven equipment.
