FASCO D1124 HVAC Motor 1/20 HP 1550 RPM 1 Speed

SKU CH-N7HZ-SYV48

Replaces original HVAC motors with a 1/20 HP shaded-pole unit running at 1550 RPM on 115 V AC with auto thermal protection

  • typeClosed Base
  • OEM replacement ensures exact fit and functionality
  • 1/20 HP motor delivers 1550 RPM for HVAC systems
  • Auto thermal protection shuts down motor at excessive heat
  • Sleeve bearings reduce friction for efficient operation
  • Open air-over design provides cooling during operation

HVAC Replacement Motor

The FASCO D1124 is an OEM replacement motor built for HVAC and refrigeration systems. It operates on 115V AC input with compatibility across 115/208–230V AC and up to 120/240V AC ranges. The shaded-pole design delivers 1/20 HP at a nameplate speed of 1550 RPM. Ring and stud mounting provides flexible installation for direct equipment fit.

Sustained Load Operation

Auto thermal protection shuts the motor down automatically when excessive heat is detected during continuous duty. The open air-over enclosure relies on system airflow for cooling while the unit runs at full capacity. Sleeve bearings reduce internal friction to maintain operational efficiency over long periods. Full-load current draw reaches 2.1 A under maximum demand.

Build and Connectivity

The open air-over enclosure design prioritises cooling performance over dust and moisture resistance. A closed base construction supports the ring and stud mounting arrangement for secure attachment. Electrical connections must accommodate the stated voltage ranges and the 2.1 A full-load amperage. This motor is not suited for environments requiring sealed enclosures or higher horsepower ratings.

Questions about this item

How much heat and noise does the 1/20 HP shaded-pole motor generate when it runs continuously at 1550 RPM?

The open air-over enclosure and sleeve bearings keep the motor cool and relatively quiet during all-day operation, while auto thermal protection shuts it down if temperatures rise too high.

What voltage supply and mounting hardware must I already have to install this D1124 motor?

You need a 115 V AC circuit (compatible up to 208-230 V or 120/240 V) and a ring/stud mounting arrangement to match the motor's base.

Will the 2.1 A full-load draw and 115 V requirement work with the older HVAC control board I plan to keep?

Yes, the motor's 115 V AC rating and 2.1 A maximum draw are within typical legacy HVAC control-board limits, and the shaded-pole design matches common older-system characteristics.
