MSM215-221-304-S-0KA by Kollmorgen

The Kollmorgen MSM215-221-304-S-0KA is a high-performance servo motor from the MSM Brushless Servo Motors series, designed to meet the rigorous demands of industrial automation. This robust 26.0 kg drive unit delivers a nominal speed of 3000 RPM and supports peak currents up to 65.1 A for rapid acceleration and precise positioning. Engineered for continuous operation, the MSM215-221-304-S-0KA features a high torque constant (Kt of 1.36 Nm/Amp) to ensure efficient energy conversion and responsive torque delivery. Its heavy-duty construction with an ST-60 shaft offers exceptional mechanical strength and reliability under high loads. With a radial shaft load rating of 209 kg at 500 RPM, this motor maintains performance even under substantial external forces.

The motor’s technical specifications are clearly defined to support system designers in selecting and integrating the MSM215-221-304-S-0KA. Key parameters include an Ambient Temperature range of 0 to 40 C and a Storage Temperature range of 30 to 70 C, ensuring wide environmental compatibility. The flange diameter measures 6190 mm, the shaft diameter is 32 mm, and the overall length is 367 mm. Electrical characteristics comprise a Ke Voltage Constant of 164 V/krpm, Winding Inductance Phase to Phase of 15.8 mH, and Winding Resistance Phase to Phase at 25 C of 0.76 3. The rotor moment of inertia is 0.0074 kgb7mb2, and the 6-pole design provides smooth torque production and low cogging torque.

Operational features emphasize the MSM215-221-304-S-0KA’s ability to handle dynamic loads and abrupt changes in demand. The stall current peak of 20.5 A enables the motor to start under heavy load conditions without stalling. With a maximum peak current capability of 65.1 A, it can accommodate surge demands during high-speed acceleration sequences. The robust ST-60 shaft material resists wear and deformation, supporting long service intervals with minimal maintenance. The specified radial load capacity of 209 kg at 500 RPM guarantees stable operation under side-load conditions commonly encountered in multi-axis systems.

This servo motor integrates seamlessly into Kollmorgen's drive and control ecosystem, supporting real-time feedback through standard encoder interfaces and allowing for advanced tuning and diagnostics. System designers can leverage its precise torque control and broad thermal tolerances in applications ranging from CNC machining centers to robotic assembly lines and material handling systems. The MSM215-221-304-S-0KA is ideally suited for demanding industrial environments where reliability, high torque density, and consistent performance are essential.
