Us Motors 6305 Psc Ac Motor 1/4 Hp 1140 Rpm Odp

Product Description

The US MOTORS 6305 is a single-phase permanent split capacitor (PSC) AC motor designed for general-purpose applications in residential and light commercial settings. Rated at 1/4 horsepower and 1140 RPM, this motor operates on a 60 Hz supply and features an open drip-proof (ODP) enclosure that allows air circulation while protecting against dripping liquids. It carries a Class B insulation rating and a 1.35 service factor, providing a reliable thermal margin above nameplate load. Automatic thermal protection is built in. A reversible rotation direction makes this motor adaptable across a range of driven equipment. Licensed HVAC techs, refrigeration technicians, and mechanical contractors routinely specify this frame size for fan and blower replacement work.

The US MOTORS 6305 fits general-purpose motor applications where a 56-frame, cradle or cradle base mount configuration is required. Typical install scenarios include evaporator fan duty, exhaust fan drives, and light-load blower assemblies in commercial refrigeration and HVAC equipment. The 5/8-inch shaft diameter and 1-7/8-inch shaft length suit standard direct-drive and belt-drive couplings used across this horsepower range. This motor is also cross-referenced as Dayton part number 6XH92, which assists technicians sourcing replacements from multiple supply channels.

Key Features

• 1/4 HP PSC motor with reversible rotation for flexible installation orientation
• ODP enclosure provides ventilation while protecting internal windings from dripping water
• NEMA 56 frame with cradle and cradle base mount options for broad equipment compatibility
• 1.35 service factor allows sustained operation above nameplate load conditions
• Built-in automatic thermal overload protection guards against damage from overheating
• Ball bearing construction supports reliable operation across extended duty cycles

Compatibility

Cross-referenced as Dayton part number 6XH92. Designed as an OEM-style replacement for general-purpose single-phase PSC motor applications requiring a NEMA 56 frame with cradle mount configuration.

Installation Notes

Installation should be performed by a qualified technician familiar with NEC requirements for motor branch circuits. Disconnect and lock out all power to the equipment before removing the existing motor or making any wiring connections. Verify that supply voltage, frequency, and rotation direction match the driven equipment requirements before energizing. Do not exceed the motor ambient operating temperature rating of 40 degrees F minimum; confirm the installation environment falls within the rated thermal range.
