Small unfinished open-frame AC/DC motor with quarter-inch shaft

Dayton

Dayton 2M277 AC/DC motor 1/15 hp 5000 RPM 115 V line protection

SKU CH-BE42-TJCRV

Universal AC/DC motor delivers 1/15 hp at 5000 RPM on 115 V single-phase power

  • 1/15 hp motor delivers compact power
  • 5000 RPM speed enables fast operation
  • 115 V AC input suits standard supply
  • 2 A full-load current aids circuit planning
  • Open enclosure allows efficient air cooling

Universal AC/DC motor for low-power tasks

This Dayton 2M277 motor delivers 1/15 hp at 5000 RPM on a 115 V single-phase supply. The open enclosure and hole-mount design suit all-angle installation in compact equipment. A 1/4 in. shaft and CCWSE rotation fit direct-drive applications. It operates at 60 Hz with a 1.0 service factor and Class A insulation.

Thermals noise and power draw

Full-load current is 1.2 A at 115 V with no built-in thermal protection. The motor is rated for a maximum ambient temperature of 40 °C. Open construction allows airflow but offers no acoustic shielding, so sound level depends on the driven load and mounting surface.

Replaces shaded-pole or small split-phase units

The jump is worth it when a universal AC/DC motor with 5000 RPM nameplate speed and all-angle mounting simplifies the drive train. It is not usable at 200 V or 208 V, so installations requiring those voltages need a different solution.

Questions about this item

How do I install the Dayton 2M277 motor with its hole-mount design and 1/4 in. shaft?

Mount the motor using the hole-mount pattern in any angle, then couple the 1/4 in. shaft to your driven equipment. The step often missed is verifying CCWSE rotation matches the load direction before tightening fasteners.

What maintenance will the open-enclosure Dayton 2M277 motor need over time?

With an open enclosure and no thermal protection, dust and debris can accumulate on windings. Plan periodic cleaning with dry compressed air and inspect the 1/4 in. shaft bearing for wear or noise, especially when running at the 40 °C max ambient limit.

What is the first limit reached when running the Dayton 2M277 continuously at full load?

The Class A insulation and 40 °C maximum ambient temperature set the thermal ceiling. At 1.2 A full-load current and a 1.0 service factor, sustained operation above 40 °C ambient will exceed the insulation rating before any other parameter.
