Dayton 53J557 Replacement Motor

The Dayton 53J557 is an OEM replacement motor designed for single-phase applications. It operates at 115V AC with a 35.5 W power rating and a nameplate speed of 1,050 RPM. This new component suits maintenance technicians restoring compatible fan assemblies. It is not for builders needing a different voltage or phase configuration.

Single-phase 115V AC motor fit

The motor features a closed-base design and draws 1.2 / 0.95 / 1.1 A at full load. It fits directly into equipment specifying this frame and electrical profile without adapter parts. The unit frees the installer from rewiring when the original specifications match exactly. Buyers without the original motor data sheet should verify compatibility first.

Upgrades worn single-phase units

This motor replaces failed or noisy single-phase units carrying the same 53J557 identifier and electrical ratings. The jump is worth it when the existing mount, shaft and wiring match the closed-base layout. It does not serve as a substitute for three-phase motors or higher-horsepower requirements.

Questions about this item

Will the 1.2 A full-load current trip a standard 15 A circuit if the motor runs continuously?

At 1.2 A the motor draws only a small fraction of a 15 A branch circuit, so sustained operation will not trip a healthy breaker.

How hot does the closed-base housing get during all-day use?

The closed-base design dissipates the 35.5 W loss through its metal frame; surface temperature stays warm but within the motor’s rated insulation class.

Does the 115 V single-phase supply need a start capacitor or run capacitor to operate this motor?

The motor is a single-phase 115 V design that requires an external capacitor matched to the 35.5 W rating for starting and running.
