Dayton 6K637 1/2 HP Motor Application

The Dayton 6K637 is a general-purpose capacitor-start motor rated at 1/2 horsepower with a nameplate speed of 1725 rpm. It uses a 56 frame size and rigid base mounting, making it suitable for industrial equipment replacements or new builds requiring this specific frame and power rating.

Voltage Flexibility and Thermal Protection

Dual-voltage windings allow operation at 115 V or 208-230 V AC, with full-load currents of 9.0 A and 4.3-4.5 A respectively. The motor is usable at 208 V. A manual thermal protector and Class B insulation support continuous duty in ambient temperatures up to 40 degrees C.

Installation Requirements Checklist

Verify that your driven equipment matches the 56 frame dimensions and shaft rotation capability of CW/CCW. Confirm the supply voltage matches either 115 V or 208-230 V at 60 Hz and that the 1.15 service factor covers the intended load. Ensure the rigid base mounting pattern aligns with your mounting surface.

Questions about this item

How often should the manual thermal protection on the 1/2 HP motor be reset during continuous duty?

The motor uses manual thermal protection; it must be reset by hand each time it trips, and the duty cycle is rated continuous at up to 40 °C ambient.

Which electrical limit is reached first when the motor runs continuously at full load?

Full-load current is 9.0 A at 115 V or 4.3 – 4.5 A at 208 – 230 V, and the 1.15 service factor defines the sustained overload ceiling.

What temperature rise should be expected from the totally enclosed fan-cooled enclosure during all-day operation?

The TEFC design dissipates heat through the external fan, and the motor is rated for a maximum ambient temperature of 40 °C while running continuously.
