Product Details：

KOLLMORGEN 6SM77S-3000-G-09 is a heavy-duty synchronous servo motor from the classic Seidel 6SM series. The letter S means resolver feedback configuration, G stands for integrated 24V de-energized holding brake, and suffix -09 represents the special shaft, flange and connector variant specially matched for old ENGEL injection molding machines and die-casting equipment. It runs at rated speed of 3000 rpm, mainly used for heavy-load injection axes, large core pull axes and heavy ejector axes, providing stable torque output and safe position locking when power fails. Resolver feedback is less sensitive to high temperature, vibration and electromagnetic noise, so it works steadily in the oil mist and noisy environment of hydraulic molding workshops.

This servo motor communicates with matched Kollmorgen SERVOSTAR servo drives via resolver signal to form a complete closed-loop motion control system. Separate circular connectors are used for power circuit and feedback circuit to reduce signal crosstalk interference. The built-in holding brake locks the rotor when power is cut off and releases when energized, which prevents the sliding of heavy mechanical components and avoids mold collision accidents. The stator winding adopts class F high-temperature insulation material, and the motor housing reaches IP64 protection grade to block dust and splash. The rotor inertia is reasonably optimized to achieve smooth acceleration and deceleration and good 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 molding process requirements. A built-in PTC temperature sensor continuously monitors winding temperature. If overheating, overload or resolver signal loss is detected, the servo drive will quickly cut off output and trigger alarm information on the HMI. The whole mechanical structure is reinforced for vibration resistance, adapting to long-time continuous cyclic production operation.

This KOLLMORGEN 6SM77S-3000-G-09 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 mounting dimension and drive control scheme.

It is a practical resolver-and-brake equipped servo spare part in automation spare parts market, combining reliable closed-loop motion control and power-off holding function for heavy-duty injection molding axes.
