Fasco D1061 4.4-Inch Shaded Pole Motor
Features: 1/20-1/30-1/60 HP, 115 Volts, 1500 RPM. This model is suitable for small blowers and compact assemblies requiring a shaded-pole design with multiple speed options.
Who it’s best for: technicians upgrading compact blower assemblies where a low to moderate horsepower and multi-speed control are needed. The three-speed range helps fine-tune airflow without changing motors.
Why selected: It provides a flexible power range in a 4.4″ frame, ideal for tight spaces and standard 115V wiring. A limitation: available speeds may be lower for high-demand applications.
Fasco D119 4.4″ Frame Open Ventilated Motor
Features: 1/11-1/25-1/70 HP, 1500 rpm, 115V, 60Hz; thermally protected; UL recognized and CSA certified; counterclockwise rotation.
Who it’s best for: applications needing protection against overheating and certified safety standards in ventilated designs.
Why selected: Robust protection and certification support broader use in HVAC and appliance contexts. Caution: open-ventilated design may require extra clearance for airflow.
Fasco D174 4.4″ Frame Open Ventilated Motor
Features: 1/10 HP, 1500 rpm, 115V, 60Hz, sleeve bearing; thermally protected; UL recognized and CSA certified; clockwise rotation.
Who it’s best for: installations needing clockwise shaft end rotation or a slightly lower horsepower in a 4.4″ frame. Useful in compact ventilation and blower modules.
Why selected: Open-ventilated design supports adequate cooling in restricted spaces. Caution: single direction rotation may limit interchangeability in some assemblies.
1/15hp 1550RPM CCW4-Speed 4.4″ D117
Features: 2.4 amps @ 115V 60Hz; shaft 1/2″ x 7 1/2″; rotation CCW; belly band or stud mount with bolt circle 3.89″.
Who it’s best for: installations needing a four-speed option in a compact 4.4″ package and a flexible mounting setup.
Why selected: Four-speed capability in a compact frame broadens compatibility. Caution: mounting compatibility should be verified with the specific assembly pattern.
Fasco D482 Blower Motor 4.4″ Frame
Features: 1/15 HP, 1550 RPM, 115V, sleeve bearing; available across typical 4.4″ frame applications.
Who it’s best for: users needing a simple, reliable blower motor in a standard frame size with sleeve bearings for smooth operation.
Why selected: Consistent 1550 RPM makes it a predictable choice for HVAC blowers. Caution: may require additional cooling in high-load environments.
Fasco D1006 4.4-Inch Shaded Pole Motor
Features: 1/4 HP, 115V, 1600 RPM; CW rotation; sleeve bearing.
Who it’s best for: high-speed, medium horsepower tasks in compact housing where clockwise rotation is standard.
Why selected: Higher RPM within the 4.4″ family; however, watch for higher current draw. Caution: 7.2 amps noted in some listings may demand ample electrical capacity.
Buying Guide
What to consider when choosing a 4.4-inch motor
- Application and load: Balance horsepower and RPM with the required airflow or mechanical load. Higher RPM can move more air, but may increase noise and power draw.
- Rotation direction: Ensure shaft end orientation (CW vs CCW) matches your equipment’s layout and pulleys or belts.
- Frame and mounting: Confirm 4.4″ frame compatibility, mounting pattern, and shaft diameter to avoid fit issues.
- Electrical requirements: Verify voltage (115V common here), phase, and current draw. Ensure your power supply can handle the motor current.
- Bearings and cooling: Sleeve bearings are common in these motors; ventilated designs (open ventilated) offer better cooling in confined spaces but may require clearance for airflow.
- Certifications: UL, CSA, or other safety certs can matter for approved use in appliances and HVAC systems.
Quick comparison at a glance
- Best for versatility: D1061 with multi-speed options and CCW rotation
- Best for safety-certified use: D119 with thermally protected, UL/CSA
- Best for compact, standard rotation: D174 with CW option
- Best for higher RPM in a compact frame: D1006
- Best all-around blower option: D482 with common 4.4″ frame
FAQ
- What is a 4.4-inch motor best used for? A: Small blowers, HVAC components, and compact equipment where space is limited and standard 115V power is available.
- Do these motors require special mounting? A: Most use standard 4.4″ frame patterns; verify bolt circle and shaft size before replacing an old unit.
- Is a shaded-pole motor suitable for continuous duty? A: Shaded-pole motors are common in intermittent or softly loaded tasks; for continuous high-load operation, consider fans or blowers with better cooling.
- How important are certifications? A: Certifications help ensure safety and compliance in appliances and HVAC systems, especially in commercial or regulated environments.
- What rotation direction should I choose? A: Match the device’s shaft end rotation to ensure correct airflow and belt/pulley alignment.
- Can I mix brands of 4.4″ motors? A: Compatibility depends on mounting, shaft dimensions, voltage, and rotation; confirm all specs before substitution.
