Dayton 7 1/2 hp Capacitor Motor
The Dayton 6K634 is a single-phase capacitor-start/run motor rated at 7 1/2 hp for 230V AC supply. It fits a 213T frame and provides rigid-base mounting in any angle. The open drip-proof enclosure suits general-purpose industrial drives where clean, dry ambient air is present. Continuous duty cycle matches equipment that runs for extended periods without interruption.
Sustained Load Performance
At full load the motor draws 30.3 A and delivers 3,530 RPM with a 1.15 service factor. Class F insulation and a 40 °C maximum ambient temperature allow continuous operation without thermal protection. The capacitor-start/run design maintains torque through start-up and steady-state running on compressors, pumps or conveyors. Not inverter rated, so speed is fixed by the 60 Hz line frequency.
Upgrade Context
Replaces failed or undersized single-phase motors in the same frame and voltage class where continuous duty is required. The jump is worth it when the existing unit lacks the 1.15 service factor or cannot meet the 30.3 A full-load demand. Not suitable for variable-speed drives, hazardous-location enclosures or applications needing thermal overload protection.

Questions about this item
How hot does the 213T frame motor run at its 40°C max ambient rating?
It is rated for continuous duty up to 40°C ambient with Class F insulation and no thermal protection, so sustained load will raise winding temperature within that class limit.
What single-phase supply and protection does the 7 1/2 hp motor need?
It requires a 230V AC, 60 Hz single-phase feed capable of 30.3 A full-load current plus a 1.15 service-factor margin, so size the breaker and wiring accordingly.
Can the rigid-base, CW/CCW motor couple directly to an older 213T-frame driven load?
Yes — the 213T frame and reversible rotation match legacy 213T mounting, but verify shaft diameter and keyway on the existing equipment before coupling.
