Each product section includes a short overview, key features drawn from the official listing, and practical notes for installation and operation.
VEVOR 3HP Air Compressor Motor
The VEVOR 3HP Air Compressor Motor operates at 230V with a full-load current of 15.5A, designed for a 56 frame and a 5/8″ keyed shaft. The shaft length is 1.88″, and the motor is suitable for single-phase configurations with a CCW rotation default. It uses open drip-proof (ODP) protection, best suited for clean, dry environments where exposure to dust and moisture is limited. Built from high-quality steel, the design emphasizes durability and extended service life in workshop or industrial settings.
Dollate 2 HP SPL Air Compressor Motor
This 2 HP, single-phase motor is rated at 60Hz with 3450 RPM, compatible with 115V/230V operation. Its 56-frame size uses a 5/8″ shaft and 1.88″ shaft length, with a CCW rotation as the standard configuration. The motor is open drip-proof (ODP) and designed for relatively clean, dry environments. Its compact structure and heat-dissipating features help maintain stable performance during extended operation in compressor systems or similar equipment.
GCCSJ 5 HP Air Compressor Motor
The GCCSJ motor delivers 5 HP with a 3450 RPM rating in a 56-frame size. It runs on 230V single-phase power and has a 5/8″ shaft with a length of 1.88″. The unit features open drip-proof construction and CCW rotation. Its compact design emphasizes high efficiency and reliable operation for air compressors and other heavy-duty applications in workshops or small industrial setups. The motor is designed for durable operation with adequate heat dissipation to support longer cycles of use.
LEUNGOO GF2054 Blower Motor (1/2 HP)
The LEUNGOO GF2054 blower motor provides 1/2 HP at 115V with a 48-frame designation. It features a reversible rotation and a 1/2″ shaft diameter within a body that measures 5-5/8″ in diameter. This motor is compatible with a range of brands including AO Smith and Packard models. While it is smaller than typical industrial compressor motors, it can be a practical option for blower or supplemental fan applications where space and power requirements are modest. Its reversible feature adds flexibility for different equipment configurations.
EMZ 3 HP 3450 RPM Single Phase Motor
The EMZ 3 HP motor operates at 230V with a 3450 RPM rating and 15A full-load current, housed in a 56-frame design. It is a single-phase CCW motor with an open drip-proof (ODP) enclosure that supports typical compressor and pump applications. The 5/8″ shaft and 1.88″ shaft length are designed for straightforward mounting on standard equipment. The motor’s construction emphasizes reliability for continuous operation in demanding environments such as workshops and light industrial settings.
Buying Guide
Key considerations when selecting a 15 HP class motor or a close alternative include efficiency, duty cycle, and mounting compatibility. For single-phase motors, ensure your power supply matches voltage and amperage requirements to avoid overheating or voltage drop issues. Frame size and shaft specifications (5/8″ shaft, 1.88″ length in many 56-frame motors) influence compatibility with pulleys, belts, and mounting plates. Open drip-proof (ODP) enclosures are common for machines operating in clean, dry environments, but consider NEMA or IP ratings if exposure to dust or moisture is likely.
Efficiency and heat management are critical for continuous operation. Motors with robust cooling features and adequate heat sinks help maintain performance over time. When evaluating options, compare full-load amps (FLA) and motor efficiency ratings to estimate operating costs and electrical load on your circuit. Rotation direction (CCW or CW) matters for belt and pulley alignment, so verify the motor’s factory setting or whether wiring changes are required for your setup.
Durability and service life are influenced by construction materials and bearing design. Frames, such as 56 and 48, offer different mounting patterns and available accessories. If you expect heavy or variable loads, a higher HP rating and a motor with precise torque characteristics may reduce downtime and replacement costs. For installations involving compressors, pumps, or blowers, confirm compatibility with your existing motor mount, shaft keying, and drive system to ensure a smooth retrofit or upgrade.
In summary, while 15 HP motors are built for demanding tasks, a range of nearby horsepower options provides flexibility for many projects. The listed motors offer a mix of voltage options, frame sizes, and rotation directions to fit diverse equipment and environments. Always verify the exact electrical requirements and mechanical fit before purchase to optimize performance and longevity.
