Dayton 31TR62 1 hp Condenser Fan Motor

The Dayton 31TR62 is a three-phase condenser fan motor rated at 1 hp with a nameplate speed of 140 RPM. It operates on 200-230/460V AC at 60 Hz and fits a 48Y frame. The motor features automatic thermal protection, Class B insulation and a continuous duty cycle rated for a maximum ambient temperature of 60 degrees C. Its open air-over enclosure and belly-band mounting suit direct-drive fan applications.

Upgrade From Single-Phase Or Lower-Horsepower Units

Replacing a single-phase motor with this three-phase design eliminates starting capacitors and reduces maintenance in compatible installations. The step up to 1 hp at 140 RPM is worthwhile when the driven load demands higher torque at low speed or when the existing motor runs near its service factor. Inverter-rated construction also allows variable-speed control where the previous unit ran only at fixed speed.

Suits Industrial HVAC

This motor suits technicians servicing condenser fans in commercial HVAC or refrigeration systems that specify a 48Y frame and 200-230/460V three-phase supply. It is not for sites limited to single-phase power or for equipment requiring a different frame size, shaft orientation or speed rating. Buyers needing a multi-speed motor or a totally enclosed enclosure should look at alternative designs.

Questions about this item

What frame size and mounting type does the 31TR62 motor use?

The motor uses a 48Y frame with belly band mounting for condenser fan installations.

How do you wire the three-phase motor for 200-230V or 460V supply?

Connect the nine leads per the nameplate diagram for low-voltage 200-230V or high-voltage 460V three-phase supply.

When should the motor bearings be inspected given continuous duty at 60°C ambient?

Inspect bearings annually or per your preventive maintenance schedule; continuous duty at 60°C max ambient accelerates grease breakdown.
