About this product
This 3HP SPL electric motor is designed for air compressor applications, featuring a 56 frame size and a 5/8" keyed shaft. It supports single-phase power with dual voltage options (115V/230V) and a base RPM of 3450. Encased in a steel shell with an Open Drip-Proof (ODP) enclosure, it offers a 75% efficiency rating. The motor is rigidly mounted and designed for counter-clockwise rotation from the shaft end, making it suitable for specific compressor setups.
Our take
This 3HP single-phase motor is a practical choice for replacing an old compressor motor or for a new build. The 115V/230V dual voltage is handy, accommodating different power configurations. With a 3450 RPM and a 5/8" shaft, it aligns with common compressor requirements. The steel shell suggests decent construction, though the Open Drip-Proof (ODP) enclosure means it's not ideal for dusty or damp conditions. The 75% efficiency is standard, but you won't get premium energy savings. It's a functional, budget-friendly option for light to medium-duty applications.
