Product Description:

The 6SM 56-M3000 is a synchronous servo motor produced by Kollmorgen within the 6SM Synchronous Servo Motors series. Installed in closed-loop motion systems, it translates drive controller commands into precise shaft rotation for packaging stations, assembly cells, and other industrial automation axes that require accurate speed regulation and repeatable positioning. The motor operates from a 400 V three-phase supply, making it suitable for industrial drive systems with the corresponding output voltage.

The motor delivers a continuous mechanical output of 2.0 kW. At this output, it turns at 3000 rpm and produces 6.4 Nm of shaft torque. Maintaining continuous operation requires 4.7 A of phase current, while momentary load surges are handled by a peak current of 19.6 A. The copper windings have an inductance of 30.0 mH and a resistance of 4.0 Ω at 20 °C. These values affect the current rise time and assist with proper drive tuning for controlled torque delivery. The electrical characteristics support smooth electromagnetic conversion and help limit torque ripple during continuous operation.

The rotor has an inertia of 10.0 kgcm², balancing responsive acceleration with position stability when the connected load changes suddenly. Heat buildup is moderated by a thermal time constant of 20 min, permitting intermittent overloads without an immediate temperature increase. For every ampere applied, the magnetic circuit produces 1.45 Nm/A of torque, while the back electromotive force scales at 124 V/1000 rpm. The drive can use these parameters for real-time vector control and accurate regulation of motor current. A standstill current of 4.8 A can be applied to maintain a static shaft torque of 7.0 Nm. Static friction is limited to 0.18 Nm, helping small motion commands produce clean shaft movement. The motor assembly weighs 8.0 kg, providing a compact package for installation on linear slides or gearbox inputs.
