Craftsman 1/2 HP Capacitor Start A.C. Motor

This is a vintage Craftsman industrial-grade electric motor, specifically a 1/2 horsepower, capacitor start A.C. motor. The unit features a 'Totally Enclosed-Fan Cooled' (TEFC) design for general applications. It is constructed with a heavy-duty cylindrical metal housing finished in a textured black coating, showing significant accumulation of shop dust and minor surface oxidation typical of a workshop environment. The motor retains its original large identification plate which provides comprehensive specifications: Model 113.122230, Cat 1223, 1725 RPM, 115/230 Volts, and a C56 frame size. Notable features include thermally protected circuitry with a manual reset push button and permanently lubricated ball bearings. The label also displays detailed wiring diagrams for low and high voltage connections. Manufactured for Sears, Roebuck and Co. in the USA, this motor likely dates from the late 20th century. The condition appears structurally sound but shows evidence of regular use, such as debris in the crevices and slight peeling of the label edges. It exemplifies robust mid-century American tool manufacturing quality.

I have conducted a visual examination of the vintage Craftsman 1/2 HP Capacitor Start A.C. Motor, Model 113.122230. Physically, the motor exhibits the hallmarks of a mid-to-late 20th-century industrial component. The cast-iron or heavy-steel C56 frame shows significant accumulation of shop dust and grease, which, while suggesting heavy use, also points to an unmolested original state. The identification plate is exceptionally well-preserved, providing clear evidence of its Sears, Roebuck and Co. provenance and US manufacture. From a market standpoint, these motors are prized by woodworking enthusiasts and restorers for their 'over-built' quality compared to modern counterparts. The TEFC (Totally Enclosed-Fan Cooled) design and dual-voltage capability (115/230V) make it highly versatile for home workshops. Rarity is low, as these were produced in high volumes, but the demand for US-made motors with ball bearings remains steady. The value is primarily driven by its utility and the 'vintage' appeal for matching tool restorations. While it appears structurally sound, the presence of surface oxidation and debris suggests it may require a bearing flush or capacitor check to ensure peak performance. Limitations: This appraisal is based solely on visual inspection. As an appraiser, I cannot verify the integrity of the internal windings, start switch, or capacitor without a load test and multimeter diagnostics. Full authentication and valuation would require an in-person 'bench test' to check for excessive vibration or electrical 'hum,' and a teardown to inspect the rotor and stator for heat damage or moisture-related corrosion.
