MSM115-62-404-E2-0KA by Kollmorgen

The MSM115-62-404-E2-0KA from Kollmorgen is a high-performance member of the MSM Brushless Servo Motors series, engineered to deliver reliable motion control in industrial automation environments. This brushless servo motor offers a continuous torque of 7 Nm and a peak torque of 22 Nm, ensuring both sustained performance and short-term overload capacity. Rated for a maximum speed of 4000 rpm, it supports rapid acceleration and dynamic response across a wide range of applications. With a rated voltage of 360 V AC and a rated current of 5.5 A, the MSM115-62-404-E2-0KA balances efficiency and power density for demanding motion tasks. Its 115 mm frame size and keyway shaft design simplify mechanical integration into existing equipment.

Technical capabilities of the MSM115-62-404-E2-0KA encompass a precise Kt (torque constant) of 0.99 Nm/Amp and a Ke Voltage Constant of 120 V/KRPM, optimizing energy conversion for tight speed regulation. The motor’s electrical profile includes a winding resistance of 3.4 Ohms and winding inductance of 16.8 mH, yielding smooth current draw and reduced electromagnetic interference. Peak electrical performance is supported by a maximum current of 26.9 A and a stall current of 7.8 A, enabling controlled start-up torque and safe operation under variable loads. A 6-pole rotor topology with a rotor moment of inertia of 0.001 kg·m² (0.0089 lb·in·s²) ensures rapid dynamic response, while the version with brake exhibits a rotor moment of inertia of 0.00138 kg·m² to maintain positional stability.

Operational features of this servo motor prioritize durability and reliability. The IP65 rating guards against dust ingress and low-pressure water jets, and the F designation supports continuous operation up to 40°C ambient temperature. At 8.5 kg net weight without brake (9.6 kg with brake), the MSM115-62-404-E2-0KA offers a compact yet rugged form factor. Its ST-60 shaft material provides high wear resistance, and the keyway configuration assures secure coupling under heavy loads. Two independent connector ports separate power and feedback lines, facilitating maintenance and minimizing electromagnetic interference. Natural convection cooling maintains optimal thermal performance without the need for auxiliary fans.

Integration of the MSM115-62-404-E2-0KA into automation systems is straightforward, thanks to standardized 115 mm mounting and industry-standard connectors. It interfaces seamlessly with Kollmorgen drives and major PLC platforms, enabling advanced features such as closed-loop vector control and programmable motion profiles. Ideal applications include CNC machining centers, pick-and-place robots, packaging machinery, and automated assembly lines where precision and speed are critical. The combination of robust mechanical design, precise feedback capability, and high torque density makes this servo motor a versatile solution for modern industrial motion control.
