Baldor EM31105
Baldor EM31105 .33HP,1140RPM,3PH,60HZ,56,3421M,ODP,F1,N
The EM31105 is a reliable industrial-grade electric motor engineered by Baldor·Reliance. Delivering 0.33 HP at a rated speed of 1140 RPM, this unit features an open drip-proof (ODP) steel enclosure built on a NEMA 56 frame, making it well-suited for general-purpose applications requiring dependable, continuous-duty performance in protected environments.
Designed for standard three-phase electrical systems operating at 60 Hz, the motor supports dual-voltage capabilities at 230V and 460V, drawing 1.9A and 0.9A respectively. It incorporates a durable Class F insulation system, a standard 0.625-inch shaft diameter, and quality ball bearings packed with Polyrex EM grease to ensure extended operating life. With an efficiency rating of 71.4% at full load and a service factor of 1.35, the EM31105 provides efficient operation and reliable torque for commercial and light industrial machinery.
