Baldor-Reliance 1.5 hp capacitor-start/run motor, 56H frame, totally enclosed fan cooled

Baldor Electric

Baldor Electric L3513 1.5 hp 56H Capacitor-Start/Run Motor

SKU CH-NMB2-57A67

Single-phase capacitor-start/run motor delivering 1.5 hp at 3,600 rpm from a 56H frame for continuous duty

  • 5 hp capacitor-start/run motor delivers strong starting torque
  • Single-phase 115/230 V operation fits standard shop wiring
  • 56H frame matches common mounting patterns
  • 15 service factor handles continuous-duty loads
  • Totally enclosed fan-cooled design protects windings in dirty environments

Application and User Fit

The Baldor-Reliance L3513 is a single-phase general-purpose motor rated at 1.5 horsepower. It suits industrial and commercial equipment requiring continuous duty at 3,600 RPM. The 56H frame and CW/CCW rotation allow direct replacement in many existing mounting configurations. It is not for applications needing three-phase power, variable-speed control, or thermal overload protection built into the winding.

Capacity and Headroom

The nameplate shows 3,600 RPM at 60 Hz with a 1.15 service factor, providing a 15 percent margin above the 1.5 hp rating for intermittent overloads. Full-load current draws 8.0 amps at 230 volts or proportionally more at 115 volts. The motor is usable at 208 volts but not at 200 volts, so voltage selection must match the supply. Single-speed operation limits use to fixed-speed loads.

Thermals, Noise and Power

A totally enclosed fan-cooled enclosure protects the windings while moving air over the frame. Class B insulation supports a maximum ambient temperature of 40 degrees Celsius during continuous duty. No internal thermal protector is fitted, so external overload protection is required by the installer. Power factor and efficiency follow standard capacitor-start/run single-phase characteristics for this frame size.

Questions about this item

Will the 56H frame and 115/230 V dual-voltage wiring match the mounting holes and supply in my older compressor?

The motor uses a standard NEMA 56H frame and is rated for 115/230 V AC single-phase, so it fits existing 56H mounts and works with either voltage by following the connection diagram on the nameplate.

How can I verify the motor is delivering its rated 1.5 hp and 3,600 RPM after installation?

Measure the running current at full load; it should read close to 8.0 A on the nameplate voltage. Confirm the shaft turns at 3,600 RPM with a tachometer and check that the totally enclosed fan-cooled housing stays within the 40 °C ambient limit during continuous duty.

Does the box include a capacitor, mounting bolts or a power cord, or must I source them separately?

The motor ships as the bare unit with a 56H shaft and pre-wired capacitor-start/run design; capacitors are internal. You will need to supply mounting hardware, a suitable power cord or conduit, and overload protection per local code.
