Product Details:

MODICON ARG 120-166-305 is a permanent magnet brushless servo motor belonging to the legacy AEG Modicon motion control family. It delivers stable torque and high dynamic response for indexing, positioning and synchronous axis control on automated machinery. This servo motor integrates a built-in incremental encoder to provide real-time shaft speed and angle feedback, forming a closed-loop control system together with the matched Modicon servo amplifier. It adopts heavy-duty industrial mechanical structure with sealed bearings and reinforced flange, suitable for continuous cyclic operation in workshop conditions. Internal winding temperature sensing provides thermal protection to avoid burnout under overload or stall events. The dedicated power and feedback connectors ensure reliable wiring connection and signal transmission. Industrial-grade design with built-in surge suppression reduces interference from surrounding power equipment. As an obsolete original electromechanical spare part, it is used for maintenance and retrofit of old Modicon motion control lines. Direct drop-in replacement keeps the existing servo drive, encoder cable and mechanical mounting layout unchanged, eliminating the need to adjust motion programs and cutting production downtime.
