5 hp Capacitor-Start/Run Motor
The Dayton 2TJ12 is a single-phase general-purpose motor rated at 5 hp and 230V AC. It delivers 1740 RPM nameplate speed with a 22.0 A full-load current. The totally enclosed fan-cooled design uses Class F insulation and a rigid base for horizontal mounting.
Replaces split-phase or shaded-pole units
Upgrading from a split-phase or shaded-pole motor is worthwhile when the application demands higher starting torque and continuous duty at 60 Hz. The capacitor-start/run design provides stronger breakaway torque for heavy loads such as compressors, conveyors or pumps.
Fits 184T frame mounting patterns
The keyed shaft and 184T frame dimensions align with standard industrial footprints, simplifying swap-outs on existing bases. CW/CCW rotation is field-reversible, and the 40 °C maximum ambient rating suits typical shop environments without additional cooling provisions.

Questions about this item
What frame size and shaft design does the 184T motor use for mounting?
The motor uses an 184T frame with a rigid base and a keyed shaft for horizontal mounting.
How do I wire the capacitor-start/run motor for 230V AC rotation?
Connect the 230V AC supply to the terminal box following the nameplate diagram to set CW or CCW rotation.
When should I replace the run capacitor on this 5 hp motor?
Replace the capacitor if the motor struggles to start, runs hot above 40°C ambient, or shows reduced torque under continuous duty.
