MSM115-34-402-M-0KA by Kollmorgen

The Kollmorgen MSM115-34-402-M-0KA is a high-performance brushless servo motor in the MSM Brushless Servo Motors series from Kollmorgen, designed for demanding industrial automation tasks. It delivers a continuous torque of 3.8 Nm and a peak torque of 12 Nm while operating at a maximum speed of 4000 RPM, achieving precise positioning in dynamic motion profiles. The motor’s optimized winding architecture results in a Winding Resistance of 8.4 Ohm, reducing heat generation under sustained loads and enhancing energy efficiency. With a compact frame weight of 6.6 kg, the MSM115-34-402-M-0KA offers an exceptional power-to-weight ratio, supporting high-density installations without sacrificing performance or reliability. Its robust construction addresses the needs of modern production lines requiring consistent torque delivery and minimal downtime.

The technical specification set for the MSM115-34-402-M-0KA encompasses a Ke Voltage Constant of 115 V/KRPM and a Torque Constant (Kt) of 0.95 Nm/Amp, enabling accurate current-to-torque conversion. It sustains a Maximum Current (peak) of 15.6 A and a Stall Current (peak) of 4.5 A, providing headroom for rapid acceleration and deceleration cycles. The motor features 6 poles and a Rotor Moment of Inertia of 0.00057 kg-m², minimizing load on the control loop for swift responsiveness. A version with integral brake increases the rotor inertia to 0.00093 kg-m² and raises the net weight to 7.7 kg, useful for safety-critical stop-and-hold functions. The Winding Inductance of 32 mH complements the resistance characteristics, delivering stable current regulation during transient events.

Operationally, the MSM115-34-402-M-0KA excels in precision and reliability. Its shaft, made from ST-60 steel, withstands substantial radial and axial loads common in industrial gearboxes and tooling interfaces. The brushless design eliminates commutator wear, prolonging maintenance intervals and supporting continuous operation in harsh manufacturing environments. Advanced electromagnetic modeling reduces cogging torque, ensuring smooth low-speed motion critical for assembly and inspection systems. Effective thermal management safeguards performance over extended cycles, while the balanced rotor minimizes vibration for quieter operation under full load.

Integration into automation systems is streamlined by compatibility with Kollmorgen’s full drive platform, allowing plug-and-play configuration and unified parameter tuning. Standard industrial mounting patterns and feedback interfaces facilitate mechanical installation and wiring, reducing engineering lead time. The motor’s predictable performance metrics enable implementation of predictive maintenance strategies in Industry 4.0 environments, improving uptime and reducing lifecycle costs. Ideal for CNC machinery, robotics, packaging equipment, and medical device assembly, the MSM115-34-402-M-0KA addresses applications where precision, reliability, and efficiency are paramount.
