Product Details：

KOLLMORGEN 6SM77K-3000-G-09 is a heavy-duty synchronous servo motor from Kollmorgen classic Seidel 6SM series. The suffix G stands for integrated 24V holding brake, and -09 represents the special shaft and connector variant of this model, which is customized to match the mounting structure and cable interface of old ENGEL injection molding machines. It has a rated speed of 3000 rpm, and it is widely used for heavy-load axes such as main injection axes, large core pull axes and heavy ejector mechanisms of medium and large injection molding equipment, providing stable torque output for hydraulic closed-loop adjustment.

This servo motor adopts resolver feedback to transmit rotor angle and speed data to matched Kollmorgen SERVOSTAR servo drives, forming a reliable closed-loop motion control system. It uses separate circular connectors for power circuit and feedback circuit to reduce electromagnetic interference generated by hydraulic pumps and solenoid coils. The stator winding uses class F high-temperature insulation material, and the motor housing reaches IP64 protection grade, effectively blocking dust, oil mist and splash in the factory environment. The rotor structure adopts optimized inertia design, supporting fast acceleration and deceleration while maintaining excellent positioning repeatability during repeated molding cycles.

Engineers can adjust speed loop gain, position loop gain and feedforward parameters through dedicated drive software according to different process schemes. Built-in PTC thermal sensor continuously monitors winding temperature. When overheating, overload or resolver signal loss is detected, the servo drive will cut off output quickly and trigger alarm to prevent mold collision and permanent motor burnout. The integrated holding brake is de-energized locking type, which can lock the rotor position reliably after power failure to avoid sliding of heavy mechanical parts. The whole mechanical structure is reinforced for vibration resistance, adapting to long-time continuous cyclic production.

This KOLLMORGEN 6SM77K-3000-G-09 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 complete replacement safely after power cut, and the original flange size, shaft dimension and drive control scheme do not need to be modified.

It is a special customized brake servo spare part in automation spare parts market, providing high-torque drive and power-off position holding function for heavy-duty motion axes of injection molding machines.
