System compatibility

6SM77K-3000-G belongs to Kollmorgen 6SM servo motor family,matched with Kollmorgen SERVOSTAR series servo drives,widely used in machine tools,packaging machinery,textile equipment and material handling systems.This is a legacy spare part for industrial equipment maintenance replacement.

Function

6SM77K-3000-G is high-performance permanent magnet synchronous servo motor integrated with 24V DC holding brake.It features high continuous torque and moderate rotor inertia,suitable for medium heavy load positioning applications.Resolver feeds back real-time rotor position to servo amplifier to realize closed-loop speed and position control.The suffix G stands for built-in power-off holding brake to lock shaft.

Installation

Install 6SM77K-3000-G via flange mounting.Align coupling accurately,connect power cable,resolver feedback cable and brake control cable.Tighten terminals and check cable shielding before power-on commissioning.

Interface

‑Power cable connector

‑Resolver feedback connector

‑Brake 24V DC connector

‑Flange mounting interface

‑Shaft with keyway

‑Shield grounding terminal

Circuit feature

Permanent magnet rotor structure,low loss stator winding,resolver position detection circuit,built-in permanent magnet brake coil,strong overload capacity,adapt to medium heavy-load frequent start-stop working condition.

Feature

6SM77K-3000-G is obsolete Kollmorgen spare part.Typical faults:bearing wear,winding insulation aging,resolver signal failure,brake coil burnout,shaft damage,connector corrosion.Inspect winding resistance,resolver signal and brake operation before replacement.

Diagnostic

When motor fails,motor overheat,abnormal mechanical noise,position deviation,resolver signal loss,overcurrent alarm,brake fails to release or lock,axis cannot run normally.

Built‑in function:Medium heavy torque dynamic output,rotary position detection,power-off shaft holding,axis speed and position control,used as Kollmorgen machine tool servo motor spare replacement.

Product Brief

6SM77K-3000-G is Kollmorgen 6SM series synchronous servo motor with resolver feedback and integrated 24V holding brake,suitable for medium heavy-load industrial positioning.Match with SERVOSTAR servo drives.Verify feedback type and brake function before ordering.ESD protection required during handling and installation.
