Product Description:
The 6SM 56-L3000 is a synchronous servo motor manufactured by Kollmorgen for the 6SM Synchronous Servo Motors series. The unit serves as a compact rotary drive element in industrial automation, where closed-loop controllers command precise velocity and position profiles. Its electromagnetic design delivers continuous torque and rapid acceleration, making the motor suitable for indexing tables, pick-and-place heads, and other motion axes that demand repeatable movement.
During normal operation, the motor can deliver 2.6 kW of mechanical power while maintaining a rated shaft speed of 3000 rpm. At that operating point, it produces a continuous torque of 8.4 Nm and draws a phase current of 6.7 A. For short-term load peaks, the current may rise to 28.3 A; this overload margin lets the drive overcome inertial or frictional spikes without stalling. The stator winding inductance of 15.8 mH filters switching harmonics from the inverter, and the 1.8 Ω phase resistance establishes copper loss and thermal behavior. These electrical parameters influence the required voltage and servo loop bandwidth.
A total mass of 10.3 kg keeps the frame light enough for moving-gantry installations, while the rotor inertia of 15.0 kg·cm² balances swift speed changes with smooth velocity regulation. Each ampere of drive current produces approximately 1.32 Nm/A of torque, simplifying gain calculations when tuning the controller. The 20-minute thermal time constant indicates how quickly the winding temperature approaches equilibrium, allowing duty cycles to remain within safe limits. Mechanical loads are supported directly by the bearings, which permit axial forces of 170 N and radial forces of 530 N. These bearing capacities support applications with combined shaft loads without requiring auxiliary bearing supports.
