Baldor Motor l3504m 1/2 Hp General Purpose Motor 56 Frame

Product Description

The BALDOR MOTOR l3504m is a 1/2 HP single-phase general purpose electric motor built for continuous-duty industrial and commercial applications. Running at 1725 RPM on a 56 steel frame with a totally enclosed fan-cooled (TEFC) enclosure, it delivers reliable operation in environments where dust, moisture, and debris are present. The cap-start, induction-run design provides strong starting torque. Rated at 115 volts or 230 volts at 60 Hz, the motor draws 7.4 amps at 115 V or 3.7 amps at 230 V. With a 1.25 service factor and Class B insulation, it handles moderate overload conditions without degrading winding life. It weighs 27 pounds and is CURUS agency approved.

This motor is suited for residential, agricultural, and light industrial installations. Typical applications include compressors, pumps, fans, farm equipment, conveyors, material handling equipment, and machine tools. The rigid base and F1 mounting arrangement make it straightforward to mount on standard fabricated bases or OEM equipment frames. The reversible shaft rotation adds flexibility for varied drive configurations. Licensed electricians and mechanical contractors are the primary installers, though experienced maintenance technicians regularly service these units in the field.

Key Features

• TEFC enclosure protects internal components from dust, debris, and moisture ingress
• Cap-start, induction-run motor type delivers high starting torque for compressor and pump loads
• Dual voltage rating — 115 V or 230 V at 60 Hz — supports a wide range of panel configurations
• 1.25 service factor allows sustained operation above nameplate load within design limits
• Reversible shaft rotation provides flexibility for varied mechanical drive setups
• Polyrex EM grease-lubricated ball bearings rated from -20 degrees F to 300 degrees F for extended bearing life
• CURUS agency approval confirms compliance with U.S. and Canadian safety standards

Compatibility

Designed as an OEM-style replacement or new-installation motor for 56 frame single-phase general purpose applications including compressors, pumps, fans, conveyors, and similar motor-driven equipment requiring a 1/2 HP TEFC motor.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NFPA 70 (NEC) requirements for motor branch circuits, including proper overcurrent protection and disconnect means. Disconnect and lock out all power before mounting or making any wiring connections. Verify supply voltage matches the motor's selected voltage tap before energizing, and confirm the driven load's frame and shaft requirements match the 56 frame and 0.625-inch shaft diameter. Do not exceed the motor's ambient temperature rating of 40 degrees C in the installation environment.
