Dayton 3LU97 Condenser Fan Motor

The Dayton 3LU97 is a single-phase condenser fan motor rated at 1/3 hp for HVAC applications. It operates on 208-230V AC power at 60 Hz with a 48YZ frame size. The motor features permanent split capacitor design with two-speed operation and automatic thermal protection. Suitable for vertical shaft-up or shaft-down mounting configurations.

Sustained Load Performance

Designed for continuous duty cycle at maximum ambient temperatures of 60 degrees C, the motor maintains its 825 RPM nameplate speed under prolonged operation. The 2.2 A full-load current draw remains stable with a service factor of 1. Insulation Class B materials support reliable long-term operation in demanding condenser environments without performance degradation.

Thermals Noise and Power

Totally enclosed air-over enclosure provides effective heat dissipation during continuous operation at 208-230V supply voltage. Automatic thermal protection prevents overheating damage under abnormal conditions. The permanent split capacitor design ensures efficient single-phase power conversion with minimal electrical noise. CW/CCW reversible rotation allows flexible installation orientation.

Questions about this item

How much heat does the 1/3 hp motor generate when running continuously at 825 RPM?

The motor is rated for continuous duty with a maximum ambient temperature of 60 degrees C and Class B insulation, so it handles sustained operation within that thermal limit.

What capacitor and wiring does the permanent split capacitor design require to start and run?

A run capacitor matched to the 2.2 A full-load rating at 208-230 V AC is needed, plus a 48YZ frame mounting stud and a 6-inch shaft for the fan blade.

Will the 48YZ frame and reversible CW/CCW rotation fit the bracket and airflow direction of my existing condenser unit?

The 48YZ frame with stud mounting and reversible rotation works in both vertical shaft-up and shaft-down positions, matching most legacy condenser housings.
