Kollmorgen MTC302A1-M2C1

Product Type:​ 3-phase permanent-magnet synchronous servo motor
Introduction:​ Part of the legacy MTC / MT30x family, designed for medium-power machine-axis motion. The MTC302 frame is a NEMA-100 style housing with a 3-stack length. It was commonly paired with Servostar S300/S700 or early AKD drives in retrofit and spare-parts contexts.
