Baldor M3531 AC Induction Motor 0.25HP 3-Phase

The Baldor M3531 is a 0.25 HP, 3-phase general-purpose induction motor with a totally enclosed fan-cooled (TEFC) enclosure and a 56-frame size, engineered for continuous duty at 60 Hz in compact industrial equipment and built around a rugged steel frame for long life in demanding environments. At 60 Hz it provides a nominal running speed of 1140 rpm under load, with a 1200 rpm synchronous speed, and it accepts 230 V or 460 V three-phase power; full-load current is typically about 1.4 A at 230 V and 0.7 A at 460 V, enabling flexible wiring configurations for common motor drives. The bearing assembly uses Polyrex EM grease and is rated for ambient temperatures up to 40 C, with no external auxiliary box or blower required, and it carries UR US approvals; its duty rating is continuous, making it suitable for constant operation in equipment like small machines, conveyors, pumps, and fans. With an efficiency around 68% at full load, the M3531 offers an economical balance of performance and energy use in a compact frame, and its integrated Baldor quality makes it a reliable choice for light-duty automation, packaging lines, and workshop machinery where steady 3-phase torque is needed.
