The SM 2014 is a heavy-duty 24-Volt Alternator Rotor (Armature Assembly) specifically designed for the Komatsu PC 200 series excavators and other heavy machinery using the 3-Pin regulator configuration. Unlike the socket-type variants, this rotor is engineered for the high-output electronic charging systems found in newer generation PC 200 machines, providing the reliability needed for 24/7 construction and mining operations.
