Fasco D116 4.4-Inch General Purpose Motor
The Fasco D116 offers 1/15 HP at 115 volts with 1500 RPM and a sleeve bearing. Its OAO enclosure and CWSE rotation match many compact blower and small machinery applications. The motor’s compact diameter and single-speed design make it suitable for replacement in older equipment and DIY projects where space is limited.
Fasco Motor 1/15 Hp CW 230V, D1126
This genuine OEM part runs at 1/15 HP with 230V input and up to 1500 RPM. Use cases include replacements in fans and small compressors that require robust, factory-grade performance. The 230V variant is a good match for equipment designed for higher-line voltage without stepping down the power supply.
Fasco D1126 3.3-Inch Shaded Pole Motor
This 1/15 HP shaded pole motor provides 230V operation with 1500 RPM and a sleeve bearing. Shaded pole designs are common in small evaporator coils and ventilation applications where simple, reliable operation is prioritized. The CCW rotation option helps match existing fan blades in compatible assemblies.
GREENHECK Exhaust Fan Motor 1/15 hp
RMG’s 1/15 hp motor delivers 115V at 1550 RPM with a 1/2-inch shaft diameter and a 2-inch shaft flat. Featuring a 5-inch body diameter and a 3-speed design, this motor is well-suited for exhaust and ventilation fans in compact spaces, offering a balance of torque and quiet operation for continuous use.
Universal Motor, 1/15 HP, Dayton
Dayton’s universal motor provides a compact option at 1/15 HP and 115V with a high no-load speed around 5,000 RPM. This type is versatile for handheld tools and some small appliances, offering good speed control potential in suitable drives and gear setups. Consider heat generation and torque characteristics for your specific application.
Fasco D1126 Open Ventilated Shaded Pole Motor
This shaded-pole evaporator and refrigeration fan motor runs at 1/15 HP and 1550 RPM with 208-230V input. It features an open ventilated design and sleeve bearing, thermally protected operation, and clockwise shaft end rotation. It’s typical for applications in evaporator coils and compact refrigeration units, where steady airflow and simple maintenance are priorities.
Packard 1/20 Hp 1550 RPM Motor
Although listed at 1/20 HP, this Packard 1550 RPM motor is commonly considered in the same family as light-duty shaded-pole motors for small fans and basic blowers. Its open enclosure, 60 Hz, and single-phase operation make it compatible with straightforward, low-power HVAC and ventilation setups where space is at a premium.
Buying Guide
- Application type: Choose shaded-pole for simple, low-cost applications, and universal or general-purpose motors for more demanding or variable loads.
- Voltage compatibility: Ensure the motor voltage aligns with your power source (115V vs 230V) to avoid the need for transformers or rewiring.
- Rotation direction: Match the rotation (CW, CCW, or CWSE) to the existing fan or shaft orientation to prevent misalignment and noise.
- Mechanical fit: Check frame size (e.g., 3.3″ vs 4.4″ diameter) and shaft dimensions to ensure mounting compatibility with existing brackets and couplings.
- Containment and enclosure: OAO vs open ventilated enclosures affect protection against dust and moisture; select based on environment.
- Thermal and protection features: Thermally protected designs prevent overheating; verify sleeve vs ball bearings for expected life and maintenance needs.
- Speed and torque: For higher RPM options (like 5000 RPM), ensure your load and drive system can sustain the resulting torque without excessive vibration.
- Replacement availability: OEM and generic options can differ in reliability and serviceability; consider vendor support and replacement parts access.
When selecting a motor, align its specifications with the equipment’s requirements, including voltage, rotation, enclosure type, and shaft geometry. For HVAC and ventilation duties, balancing simplicity, durability, and compatibility will yield the best long-term performance.
