FASCO D1103 HVAC Motor 1/20 HP 1500/1300rpm Stud

SKU CH-5HWW-4QB7N

Single-phase shaded-pole HVAC motor delivers 1/20 hp at 1500/1300 rpm with stud mounting for 208-230 V systems

  • typeClosed Base
  • 1/20 hp motor delivers 40 W output power
  • Dual-speed operation at 1500/1300 rpm for airflow flexibility
  • 208-230 V AC supply suits standard HVAC circuits
  • Auto thermal protection with Class B insulation guards against overheating
  • Stud mounting on steel frame enables secure direct installation

HVAC Replacement Motor

This FASCO D1103 is an OEM replacement motor built for single-phase shaded-pole applications. It delivers 1/20 hp with a 3.3 frame and 40 W output at 60 Hz. The motor runs on 208-230V AC and draws 1.2 / 1.4 A full-load amps. It is designed for open air-over cooling in HVAC equipment.

Stud-Mount, Single-Speed Operation

The unit suits technicians who need a direct stud-mount motor with CCWSE shaft rotation and auto thermal protection. Insulation class B and a 40 °C max ambient suit standard indoor installations. It is not usable at 200V, so buyers on 200V supplies must look elsewhere. The single-speed design also excludes variable-speed requirements.

Sustained Load Behaviour

Under continuous operation the motor maintains its 1500/1300 rpm nameplate speeds at 208-230V with a 1.0 service factor. Auto thermal protection cycles the winding if temperature rises above the class B limit. The steel frame and open enclosure dissipate heat without forced airflow. Performance at 208V is confirmed; operation at 200V is not supported.

Questions about this item

What voltage supply must I already have for this 208-230V AC motor to operate?

The motor requires a 208-230V AC single-phase supply; it is usable at 208V but not at 200V.

Will this 3.3 frame stud-mount motor fit the same mounting pattern as my existing shaded-pole unit?

It uses a stud mounting type on a 3.3 frame steel body, so match the stud spacing and shaft orientation (CCWSE) to your current housing.

How can I confirm the motor is running correctly after installation?

Verify the shaft turns counter-clockwise from the shaft end at 1500/1300 RPM nameplate speed and that current draw stays near 1.2/1.4 A full-load amps without the auto thermal protection tripping.
