About this product
This 3HP SPL electric motor is specifically designed for air compressor use, featuring a 56 frame size and a 5/8-inch keyed shaft. It operates on single-phase power with versatile 115V/230V input, delivering 3450 RPM. The motor is constructed with a steel shell and an Open Drip-Proof (ODP) enclosure, providing 75% efficiency. It offers a counter-clockwise rotation (CCW) when viewed from the shaft end and is built for rigid mounting, suitable for specific integration needs.
Our take
If you're in the market for a dependable motor for your air compressor, this 3HP SPL model offers decent value. The ability to run on either 115V or 230V single-phase power is incredibly convenient, making it adaptable to various workshop electrical setups. It delivers a solid 3450 RPM, which is suitable for many compressor pumps. My only caution is the Open Drip-Proof (ODP) enclosure; it's fine for clean indoor environments, but I wouldn't place it where it could get wet or excessively dusty. The 75% efficiency is pretty standard for this price point.
