EDGE Industrial EMZ 3.7HP Compressor Duty Motor
Edge Industrial EMZ offers a single-phase, 3.7 HP motor designed for compressor duty. It features a 56 frame, 3450 RPM, and a 5/8″ shaft diameter. This model is suited for replacement scenarios where the existing motor is labeled as 5HP SPL or SPL with a full-load amp rating between 15-17A at 230V. The shaft rotation is counterclockwise when viewed from the shaft end, and rotation is not reversible. This motor provides a straightforward swap for compatible compressor systems, with emphasis on durability and compatibility within standard 56-frame footprints.
VEVOR 2HP Air Compressor Electric Motor
VEVOR’s 2HP motor runs at 3450 RPM on a 56 frame with a 5/8″ keyed shaft. It supports both 115V and 230V single-phase operation with full-load amps of 20/10. The unit uses a 1.88″ shaft length and includes a standard 5/8″ shaft, along with a durable open drip-proof design intended for clean, dry environments. It’s a practical option for small to mid-sized compressor setups that require reliable, straightforward compatibility with common electrical configurations.
VEVOR 1 HP Electric Motor For Various Applications
This 1 HP TEFC (Totally Enclosed Fan C cooled) motor from VEVOR is designed for air compressors and general-purpose use. It operates at 1725 RPM on a 56 frame with a 5/8″ shaft and 1.88″ shaft length. The motor supports dual voltage (115V/230V) and interchangeable CW/CCW rotation, enabling flexible installation to suit various equipment configurations. Its rugged construction supports reliable operation in typical workshop environments.
CHIOWO GF2025 Electric Fan Motor
CHIOWO GF2025 is a 1/4 HP motor with 1725 RPM at 115V and a 48-frame size. It features a reversible rotation option, a resilient cradle base, and a 1/2″ x 1 1/2″ diameter shaft. The shaft height is approximately 3″, making it suitable for belt-driven fan replacements or small blower assemblies. The design emphasizes quiet operation and reliable ball bearings for durable, steady performance in HVAC applications.
CHIOWO GF2034 Blower Motor
CHIOWO GF2034 is a 1/3 HP blower motor, rated at 115V, 60 Hz, 1725 RPM within a 48-frame size. It operates with a 1/2″ shaft diameter and a 1/2″ to 5/8″ shaft compatibility in many AO Smith-compatible HVAC systems. The motor’s belt-drive compatibility, reversible rotation, and reduced noise profile make it well-suited for light-duty blower replacements in air handling equipment and residential HVAC units where quiet operation is valued.
Buying Guide: Key Purchase Considerations
- Frame size compatibility: Most of the listed motors use standard 48 or 56 frames. Verify the existing motor’s frame to ensure a snug fit and proper mounting alignment in your equipment.
- Power and voltage: Motors here range from 1/4 HP to 3.7 HP and support either 115V or 230V single-phase operation. Confirm your power supply and any existing harness or terminal block compatibility before purchasing.
- Rotation direction: Reversible CW/CCW motors offer flexible wiring, making installation easier in belts and pulleys configurations. If a replacement requires a specific rotation, ensure the model supports the required direction.
- Duty cycle and environment: Open drip-proof or TEFC designs suit clean, dry spaces but may require additional protection in dusty or humid environments. Choose a model with appropriate IP ratings or enclosures for your site.
- Mounting and shaft details: Note shaft diameter, length, and keyway size. A 5/8″ shaft is common in 56-frame motors, but verify shaft specs to avoid misalignment with pulleys and couplings.
- Maintenance and bearings: Ball bearings typically offer longer life and smoother operation in intermittent use. Check service life expectations and noise levels to match your setting.
- Replacement compatibility: If you are replacing a legacy model, cross-check with original model numbers and substitute with matching frame size, HP, and rotation to minimize downtime.
- Availability and support: Some brands provide extensive online documentation, installation guides, and spare parts. Consider brands with accessible customer support for field adjustments and troubleshooting.
