VEVOR 2HP Air Compressor Electric Motor
This 2HP motor by VEVOR is a single-phase, dual-voltage unit compatible with both 115V and 230V systems. It runs at 3450 RPM and provides a full-load current of 20A at 115V or 10A at 230V. The 56-frame size, 5/8″ keyed shaft, and 1.88″ shaft length are standard for many 2HP compressors, with a 0.188″ keyway. The unit uses a robust steel construction and is designed for open drip-proof (ODP) operation, best suited to clean, dry environments to maximize service life. The factory rotation is CCW, but the motor is capable of CW rotation if configured accordingly. This model emphasizes reliability and straightforward replacement in existing systems.
JIAXINPRO 2HP Air Compressor Motor
JIAXINPRO’s replacement motor delivers 2HP with a 3450 RPM rating and dual voltage capability for 115V or 230V operation. It uses a 56-frame housing and a 5/8″ keyed shaft, with a focus on quiet performance at around 75dB for a motor of its class. The design is specifically tailored for air compressor replacement, offering a reversible single-phase configuration that reduces downtime when upgrading older, louder units. The IP23-rated housing adds protection against dust and moisture, supporting longer life in typical workshop environments.
VEVOR Air Compressor Motor, 2HP Oil-Free
This VEVOR motor is an oil-free, 2HP unit designed to deliver up to 5.2 CFM at 90 PSI with a maximum of around 1680 RPM for the pump it drives. Its oil-free design reduces maintenance while providing a clean air supply for tasks like tire inflation, auto repair, spraying, and woodworking. The motor emphasizes low noise (about 78dB) and includes heat-dissipating features like multiple cooling fins and large cooling fans. The focus is on reliable duty in environments where oil exposure is undesirable and consistent performance is needed over extended use.
Air Compressor Motor 2HP SPL (Cuilvu)
The Cuilvu 2HP motor features a 56-frame, 5/8″ keyed shaft and an open drip-proof (ODP) design suitable for clean, dry indoor environments. It runs up to 3450 RPM and uses a rolled steel shell housing for durability. The product highlights continuous operation with a focus on safe, long-lasting service life. This motor is a practical option for standard air compressor systems where straightforward installation and stable operation are priorities.
GCCSJ 2HP SPL Air Compressor Motor
The GCCSJ motor offers a 2HP SPL configuration with a 56-frame housing, 5/8″ keyed shaft, and 1.88″ shaft length. It supports dual rotation (CCW/CW) for compatibility with a wide range of compressor models. The unit uses an open drip-proof design and is built with a rolled steel shell for durability. It is positioned as a reliable, flexible option for users who may need to interchange rotation direction depending on the wiring set-up of their equipment.
Buying Guide
- Voltage compatibility: Most 2HP motors support 115V and 230V; confirm your power supply and any voltage-doubling or conversion needs before selecting a model.
- Frame and shaft: Ensure the motor frame is 56 and the shaft is 5/8″ with a 1.88″ length, plus a 0.188″ keyway. These specifications align with many standard compressor units.
- Rotation direction: Some motors are reversible (CW/CCW). If your compressor requires a specific rotation, choose a reversible model or plan for a wiring change.
- Open drip-proof (ODP) design: ODp housings are best in clean, dry environments. For dusty or humid settings, consider additional enclosure or filtration to extend life.
- Duty and cooling: Look for robust cooling features and heat dissipation. A motor with better heat management will last longer under continuous operation.
- Maintenance needs: Oil-free motors reduce ongoing maintenance but may have different service considerations than oil-lubricated units. Weigh your maintenance tolerance and operating environment.
- Replacement and compatibility: When upgrading, verify mounting holes, shaft alignment, and electrical connections to minimize downtime and ensure a smooth swap with existing equipment.
For buyers prioritizing quiet operation, look for models rated around 75-78dB. If you need flexibility for home vs. shop use, dual-voltage motors simplify power supply considerations. Durability is often enhanced by a rolled steel shell and IP-rated housings, especially for replacement projects in professional settings.
