This 3 HP 3450 RPM electric motor is a premium replacement option for air compressors and other high-torque equipment requiring continuous-duty power. Designed to handle the intense startup load of compressor pumps, this motor also works well in industrial or commercial settings where consistent, heavy-duty performance is a must.

Built with a standard 56 frame, it offers a drop-in replacement for many compressor systems that require a 5/8" shaft with a 2-3/8" length and 3/16" keyway. The motor features a non-reversible counter-clockwise (CCW) rotation when facing the shaft, so it’s important to verify your rotation direction prior to installation.

With a single-phase 230V power supply, this motor delivers solid, reliable performance in environments where 230V is the standard. It also includes manual reset thermal overload protection, which helps safeguard the motor from overheating and ensures long-term durability even in demanding conditions.

The Open Drip Proof (ODP) design helps regulate heat by allowing proper ventilation while still protecting internal components from debris in the environment. With an insulation class of F and a 40°C ambient temperature rating, it’s engineered to withstand daily wear in industrial or commercial shops.
