Capacitor-Start Motor for General Use

The Dayton 5K193 is a single-phase, capacitor-start motor rated at 1/2 hp and 1,725 RPM. It operates on 115/208-230V AC at 60 Hz, making it suitable for a range of industrial and workshop machinery. The 48 frame size and rigid base mounting allow for straightforward installation on compatible equipment.

Thermal Protection and Power Draw

The motor features automatic thermal protection and Class F insulation rated for a maximum ambient temperature of 40 degrees C. It draws 8.5 amps at 115V and 4.2 to 4.3 amps at 208-230V, with a service factor of 1.0 for continuous duty cycles. The totally enclosed fan-cooled design helps manage heat without external ventilation.

Build Integration and Mounting Flexibility

This unit uses a closed-base, rigid mounting configuration that accepts all-angle installation. The shaft rotates in both clockwise and counter-clockwise directions, providing adaptability for various drive setups. Buyers needing a different frame size, voltage range, or enclosed wiring compartment should verify compatibility before purchase.

Questions about this item

How do I wire the dual-voltage 115/208-230V capacitor-start motor for 230 V and which step is often missed?

Connect the leads for the high-voltage setting shown on the nameplate diagram and verify the capacitor is rated for 230 V; the step most often missed is re-configuring the internal jumper links to match the selected voltage.

What maintenance will the 48 frame TEFC motor with Class F insulation need during continuous duty?

Periodically clean the fan cover and cooling fins to maintain airflow, check the auto thermal protector for nuisance trips, and inspect the capacitor for bulging or leakage after extended 40 °C ambient operation.

At what point does the 1.0 service factor limit sustained output on this 1/2 hp motor?

The 1.0 service factor means the motor cannot exceed its 1/2 hp nameplate rating; drawing more than 8.5 A at 115 V or 4.2-4.3 A at 208-230 V continuously will trigger the auto thermal protection.
