Product Details：

KOLLMORGEN 6SM57S-3.000 is a medium frame synchronous servo motor from the classic Seidel 6SM series, widely fitted on ENGEL injection molding machines and die-casting automation systems. The suffix 3.000 represents its rated speed of 3000 rpm. This S variant is equipped with resolver feedback instead of optical encoder, offering outstanding resistance to shock, high temperature and electromagnetic interference, which is very suitable for harsh hydraulic machine environments with heavy oil mist and vibration. It is commonly used for core pulling axes, ejector axes and auxiliary hydraulic closed-loop adjustment axes on plastic molding equipment.

This servo motor adopts resolver as position feedback element, transmitting rotor angle and speed data back to matched Kollmorgen SERVOSTAR servo drives to form stable closed-loop motion control. It uses two separate circular connectors for power circuit and feedback signal circuit to avoid cross interference. The stator winding adopts high-grade insulation material, and the motor housing reaches IP64 protection grade, preventing dust and oil mist from entering the internal electromagnetic structure. The rotor adopts optimized inertia design, realizing smooth acceleration and deceleration without obvious overshoot during repeated molding cycles.

Engineers can tune speed loop gain, position loop gain and feedforward parameters through dedicated drive software to match different machine cycle requirements. 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 rapidly and trigger alarm to avoid mold collision and permanent winding damage. The overall mechanical structure is reinforced for vibration resistance, supporting long-time continuous cyclic operation.

This KOLLMORGEN 6SM57S-3.000 is end-of-life from the original manufacturer, and it is supplied in the industrial automation aftermarket as a tested replacement spare part for legacy ENGEL injection molding machines. Maintenance technicians can replace the faulty motor safely after cutting off power supply, without modifying the original flange mounting dimension and drive control program.

It is a popular resolver-type servo spare part in industrial automation spare parts market, delivering reliable torque and position feedback capability for heavy-duty auxiliary axes of injection molding machines.
