About this product
This is a 3HP SPL electric motor specifically designed for air compressors, featuring a 56 frame size and a 5/8" keyed shaft. It operates on single-phase power, with a dual voltage capability of 115V/230V and a base RPM of 3450. Constructed with a steel shell and an Open Drip-Proof (ODP) enclosure, it offers an efficiency of 75%. Its non-reversible CCW rotation and rigid mounting make it suitable for dedicated air compressor applications.
Our take
For those needing a replacement or building a new air compressor, this 3HP single-phase motor is a solid option. The 115V/230V compatibility is a practical feature, allowing for flexible wiring depending on your workshop's setup. The 3450 RPM and 5/8" keyed shaft are standard for many air compressor applications. However, the Open Drip-Proof (ODP) enclosure means it's best suited for dry, clean environments. While the 75% efficiency is acceptable, it's not top-tier. Overall, a good, straightforward motor for the price.
