DAYTON 6K030 Split-Phase Belt-Drive HVAC/R Motor, 1/3 HP, 115V, 1725 RPM, 56Z Frame, ODP, Ball Bearings, 1/2″ × 1-1/2″ Shaft (flat), Cradle Base, SF 1.35, Auto Thermal, Reversible CCWSE/CWLE — includes 1/2″→5/8″ bushing

DAYTON 6K030 Split-Phase Belt-Drive HVAC/R Motor, 1/3 HP, 115V, 1725 RPM, 56Z Frame, ODP, Ball Bearings, 1/2″ × 1-1/2″ Shaft (flat), Cradle Base, SF 1.35, Auto Thermal, Reversible CCWSE/CWLE — includes 1/2″→5/8″ bushing Condition: New. Factory motor with cradle-base mount. Capacitor not required (split-phase). Includes 1/2″ to 5/8″ shaft bushing. Description The DAYTON 6K030 is a belt-drive fan/blower motor built for HVAC/R duty where reliable, continuous operation and easy service matter. Its split-phase design provides smooth start-ups, while a robust 56Z rolled-steel frame with open-dripproof (ODP) cooling keeps the motor compact and well-ventilated in equipment rooms. With 1/3 HP, 1725 nameplate RPM, 115 VAC, ball bearings, and a stout 1.35 service factor, this motor is an excellent choice for belt-driven blowers and fans. The reversible rotation (wired for CCWSE/CWLE) and cradle base simplify field replacements, and the included 1/2″→5/8″ bushing helps match common pulley/bore combinations. Features HVAC/R belt-drive duty: ideal for supply/return fans, cabinet blowers, evaporative coolers Split-phase, single-speed: smooth starts without a run capacitor Reversible rotation: wire for CCWSE/CWLE to match your pulley orientation Ball bearings: longer life and higher belt tension tolerance vs. sleeve designs ODP enclosure: efficient cooling for indoor mechanical spaces Cradle base mount: easy belt alignment and tensioning in tight cabinets High Service Factor (SF 1.35): extra thermal and load margin for tough days Auto thermal protection: built-in overload reset for safety Includes 1/2″→5/8″ bushing: flexible pulley fit-up Specifications (Motor) Brand / MPN: DAYTON 6K030 Application/Sub-Application: HVAC/R — Belt Drive Fan/Blower HP: 1/3 Voltage / Phase / Frequency: 115 VAC, 1-Ph, 60 Hz Full-Load Amps: 5.8 A Nameplate RPM: 1725 (range 1701–1800) Number of Speeds: 1 Design / Duty: Split-Phase, Continuous Service Factor: 1.35 Thermal Protection: Automatic Insulation Class: B Max Ambient / Inlet Air: 104 °F (40 °C) Enclosure: Open Dripproof (ODP) Frame / Material: 56Z, rolled steel Mounting Type / Position: Cradle Base, All-angle Bearings: Ball Shaft: 1/2″ dia × 1-1/2″ L, flat (includes 1/2″→5/8″ bushing) Nominal Efficiency: 65% Rotation: CW/CCW (field reversible => CCWSE/CWLE) Dimensions: Overall 9-15/16″ L; 8-7/16″ less shaft; 5-5/8″ body dia Ring-to-ring center: 7-15/16″; Resilient ring dia: 2-1/2″ Standards: UL Component Recognition (E37403); CSA (258501) Applications / Spheres of Application Belt-drive blower sections in air handlers and rooftop units Return or supply fans in residential/light commercial air cabinets Evaporative coolers & make-up air units (indoor, ODP-appropriate) Shop ventilation & filtration cabinets (with separate belt & pulley) Fan retrofits where a 56Z, 1725 RPM, 1/3 HP motor is specified Cross-Referenced Models Replaces/alternate for Dayton 4C445 (blower assembly this motor commonly pairs with; verify pulley/rotation and amperage) Comparable Motors (match on HP/RPM/Frame/Mount) NBK Parts: 56Z 1/3 HP, 115V, 1725 RPM, ODP, cradle base, ball bearings, reversible CCWSE/CWLE (select by shaft length and FLA) Century / Regal: C566 series (1/3 HP, 1725 RPM, 56Z, ODP, cradle) U.S. Motors / Nidec: NDL/FDL belt-drive 1/3 HP 1725 RPM, ODP, cradle base Marathon: Belted Fan series 1/3 HP 1725 RPM 56Z frame Packard: direct belt-drive 1/3 HP 1725 RPM cradle base options (Compare shaft diameter/length, SF, amps, and base footprint before substituting.) What This Motor Can Be Part Of Belted blower assemblies (forward-curved housings with adjustable pulley) Filtration & HEPA cabinets (indoor clean-air duty) Custom fan skids with vibration isolation, adjustable motor bases, and guards Accessories often paired: fixed/adjustable pulleys, matched V-belt, adjustable cradle/base plate, belt guard, AMCA-style inlet cone, starter or disconnect. Installation Notes (Quick) Set pulley for required RPM/CFM; align sheaves and tension belts per manufacturer specs. Wire for the required rotation (use CCWSE/CWLE convention) and confirm airflow before finalizing guards. Verify line voltage and FLA (≈5.8 A) after run-in; ensure ODP is acceptable for the location (dry, clean, indoor). Maintain bearing alignment; re-tension belts after the first few hours of runtime.
