Product Details：

KOLLMORGEN 6SM77S-3000-V is a medium-large frame synchronous servo motor from the classic Seidel 6SM series. The S stands for resolver feedback, and the suffix V indicates a special voltage variant optimized for specific machine supply conditions, widely matched with ENGEL injection molding machines and die-casting automation equipment. It has a rated speed of 3000 rpm. Resolver feedback can withstand high temperature, strong vibration and electromagnetic interference from hydraulic pumps and solenoid coils, which is very suitable for harsh oil mist workshop environments. It is mainly used for heavy-load injection axes, core pull axes and large ejector axes, providing stable continuous torque for closed-loop speed and pressure adjustment of hydraulic axes.

This servo motor transmits rotor angle and speed signals to the supporting Kollmorgen SERVOSTAR servo drives through resolver, forming a complete closed-loop motion control system. Separate circular connectors are adopted for the power circuit and feedback circuit to avoid signal crosstalk and interference. The stator winding uses class F high-temperature insulation material, and the motor housing reaches IP64 protection grade, effectively blocking dust and splashing oil mist. The rotor inertia is reasonably optimized to achieve smooth acceleration and deceleration, and the positioning repeatability remains stable during long-cycle repeated molding production.

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

This KOLLMORGEN 6SM77S-3000-V servo motor has been discontinued by the original manufacturer. It is supplied in the industrial automation aftermarket as a tested replacement spare part for legacy ENGEL injection molding equipment. Maintenance technicians can replace the faulty motor safely after power cut, without modifying the original flange installation size and drive control scheme.

It is a practical resolver-type servo spare part in the automation spare parts market, delivering reliable torque and position feedback for the core heavy-duty motion axes of injection molding machines.
