  • 1 hp three-phase power drives demanding condenser fans
  • 825 RPM nameplate speed matches OEM cooling specs
  • Dual-voltage 208-230/460 V suits common industrial supplies
  • Inverter-rated design enables variable-speed control
  • Belly-band mount fits 56YZ frame housings directly

Industrial Condenser Fan Motor

The Dayton 20RK78 is a three-phase condenser fan motor rated at 1 hp and 825 RPM. It operates on 208-230/460V AC power at 60 Hz with a 56YZ frame. The motor features continuous duty cycle, Class F insulation, and a maximum ambient temperature rating of 60 degrees C. It is designed for industrial HVAC and refrigeration applications requiring reliable airflow.

Replaces Worn Three-Phase Fan Motors

This unit serves as a direct replacement for failed three-phase condenser fan motors in commercial cooling equipment. The upgrade is worth it when the existing motor shows reduced airflow, overheating, or bearing noise. Inverter-rated construction allows compatibility with variable frequency drives for speed control. The 1 hp output matches original specifications for consistent system performance.

Fits 56YZ Frame Mounting Configurations

Belly band mounting secures the motor in standard 56YZ frame positions without additional brackets. Open air over enclosure design requires adequate ventilation in the installation area. CW/CCW rotation flexibility accommodates both clockwise and counterclockwise fan blade configurations. T-Stat thermal protection automatically shuts down the motor during overheating conditions to prevent winding damage.

Questions about this item

What size belly band mount does the 56YZ frame motor require?

The motor uses a 56YZ frame belly band mount; match the band to that frame size when securing it to the condenser housing.

How do I wire the three-phase motor for 208-230 V or 460 V operation?

Follow the nine-lead connection diagram on the nameplate: configure for low voltage 208-230 V at 5.2 A or high voltage 460 V at 2.6 A, and verify rotation is CW or CCW as needed.

When should the internal T-Stat thermal protector be checked or the motor replaced?

Inspect the T-Stat protector if the motor trips during continuous duty at 60 °C ambient; replace the motor if the protector cannot reset or insulation class F degrades.
