Product Details：

KOLLMORGEN 6SM77K-3000 is a high-torque permanent magnet synchronous servo motor belonging to the classic Seidel 6SM series, widely deployed on medium and large ENGEL injection molding machines and die-casting automation lines. The K variant is designed with high-torque winding configuration, rated speed at 3000 rpm. It can provide stable continuous torque output for heavy-load motion points such as main injection axes, large core pull units and heavy ejector mechanisms, which is the core motion component for closed-loop speed and pressure regulation of hydraulic axes on plastic molding equipment.

This servo motor is equipped with high-resolution position feedback device to transmit rotor angle, speed and position signals to the matched Kollmorgen SERVOSTAR servo drive, forming a complete closed-loop motion control system. It adopts independent circular connectors for power cable and feedback cable to isolate signal transmission and reduce electromagnetic interference caused by hydraulic pumps and solenoid coils. The stator winding is made of class F insulating material, and the motor housing has IP64 protection grade, effectively blocking dust, water splash and oil mist in the factory environment. The rotor adopts optimized inertia design, which can realize fast acceleration and deceleration response while maintaining stable positioning repeatability during repeated high-speed molding cycles.

Engineers can adjust speed loop gain, position loop gain and feedforward parameters through Kollmorgen dedicated drive software according to different process requirements. A built-in PTC temperature sensor continuously monitors winding temperature. When overheating, overload or feedback signal loss is detected, the servo drive will quickly cut off output and trigger an alarm to prevent mold collision and permanent burnout of the motor winding. The whole mechanical structure is reinforced for vibration resistance, suitable for long-time S1 continuous production operation.

This KOLLMORGEN 6SM77K-3000 servo motor has been discontinued by the original manufacturer. It is available in the industrial automation aftermarket as a tested replacement spare part for legacy ENGEL injection molding equipment. Maintenance technicians can complete replacement safely after power cut, without changing the original mounting flange size and drive control scheme.

It is a high-demand medium-large frame servo spare part in the automation spare parts market, providing sufficient high-torque driving capacity for the main closed-loop axes of injection molding machines.
