Dayton VED140U2918.6G Definite Purpose HVAC Motor 1/2 hp 1150 RPM 208-230/460V 48YZ Frame

SKU CH-0QK2-KP40C

Three-phase HVAC motor delivering 1/2 hp at 1150 RPM on 208-230/460 V with a 48YZ frame

  • 1/2 hp output drives HVAC equipment reliably
  • Three-phase 208-230/460V AC suits industrial power supplies
  • 1150 RPM nameplate speed matches OEM specifications
  • Continuous duty at 40 °C ambient handles demanding cycles
  • 48YZ steel frame fits standard HVAC motor mounts

HVAC Three-Phase Motor 1/2 hp

This Dayton definite-purpose motor delivers 1/2 hp at 1,150 RPM for HVAC equipment. It operates on three-phase power at 208-230/460V AC with full-load currents of 2.1-2.3 A or 1.2 A. The 48YZ frame uses steel construction and carries a Class B insulation rating for continuous duty.

Horizontal-mount continuous-duty applications

Suits replacement of OEM HVAC motors that require horizontal mounting and 60 Hz supply. Not usable at 200 V, so installations limited to 200 V mains must select a different unit. Buyers needing a different frame size, voltage range or mounting orientation should look elsewhere.

48YZ frame with 208-230/460V rating

The 48YZ frame and 208-230/460V voltage rating are the critical compatibility factors. Verify that the driven equipment matches this frame and that the site supply is within the stated range before purchase.

Questions about this item

How do I install the 48YZ frame motor and what step is often missed?

Mount the 48YZ frame horizontally on a steel base, wire for 208-230V or 460V three-phase at 60 Hz, and verify the nameplate shows 1150 RPM; the step often missed is confirming the supply voltage is not 200V, which the motor cannot use.

What maintenance will the Class B insulation need over time?

With Class B insulation rated for a maximum ambient temperature of 40 degrees C and continuous duty, the main maintenance is keeping ventilation openings clean and checking that bearing temperatures stay within design limits during extended operation.

What limit appears first when the motor runs continuously at full load?

The 40 degrees C maximum ambient temperature for Class B insulation is the first limit reached under sustained full-load operation, especially when the motor draws 2.1-2.3 A at 208-230V or 1.2 A at 460V.
