Product Details：

KOLLMORGEN 6SM56-L3000 is a medium-frame permanent magnet synchronous servo motor from the classic Seidel 6SM series, widely matched with ENGEL injection molding machines and die-casting automation systems. The L version represents the long stator variant inside the 6SM56 family, delivering higher continuous torque and power than S and M variants, with a rated speed of 3000 rpm. It is commonly used for main hydraulic valve drives, core pull axes and heavy-duty ejector axes on plastic molding equipment, demanding stable torque output under continuous cyclic load.

This servo motor integrates high-resolution built-in encoder for closed-loop position and speed feedback. It adopts separate power connector and feedback connector layout to isolate power noise from position signal lines, which can effectively suppress electromagnetic interference generated by hydraulic pumps and switching solenoid coils. The stator winding adopts high-class F insulation, and the motor housing achieves IP64 protection grade, resisting dust and oil mist inside the workshop environment. The rotor is designed with optimized inertia balance, supporting smooth acceleration and deceleration without position overshoot during molding cycles.

Engineers can adjust speed loop gain, position loop gain and feedforward parameters through Kollmorgen SERVOSTAR drive software to adapt to different machine motion requirements. Built-in PTC temperature sensor continuously monitors winding temperature. When overheating, overload or encoder signal loss is detected, the servo drive will trigger rapid shutdown and alarm output to prevent mechanical collision and permanent winding burnout. The overall mechanical structure is reinforced for vibration resistance, suitable for long-time S1 continuous operation.

This KOLLMORGEN 6SM56-L3000 is end-of-life from the original manufacturer, and it is available in the industrial automation aftermarket as a tested replacement spare part for legacy ENGEL injection molding machines. Maintenance technicians can replace the motor safely after power cut, and the original flange mounting size and drive control scheme do not need to be redesigned.

It is a high-demand medium-power servo spare part in the aftermarket, providing steady high-torque motion capability for heavy-load auxiliary axes of injection molding equipment.
