Product Description:

The Kollmorgen MSM115-89-402-E2-2KA serves as a high-performance servo technology that offers peak torque of 32Nm and continuous torque of 10Nm. The MSM brushless servo motor targets industrial environments with demanding conditions to perform precise motion control operations. Its optimized 0.0016 kg-m² rotor inertia allows quick acceleration and deceleration when used for applications that need fast direction shifts along with dynamic load adjustments. The MSM115-89-402-E2-2KA features a strong ST-60 steel shaft that enables it to handle heavy-duty automation mechanical stress. During operation the servo motor produces smooth torque delivery with reduced vibration by maintaining stable current characteristics through its 12mH phase-to-phase winding inductance.

The 11kg small-sized unit contains sophisticated thermal control elements that enable it to sustain suitable operating temperature ranges during multiple successive periods of high-load operating conditions. The motor design uses electromagnetic principles to reduce torque ripple which ensures smooth motion required for exact manufacturing operations. Turned brushless in construction this motor eliminates standard brush motor maintenance needs and provides superior efficiency and improved service period duration. System integrators gain advantages from using the motor because it has standardized mounting interfaces that work with Kollmorgen's extensive drive portfolio. The system features precise feedback tools suitable for automated control systems that need accurate position tracking. The use of advanced winding techniques leads to lower electrical energy losses that boost the energy efficiency of systems during ongoing operation.

Industrial automation engineers should consider the MSM115-89-402-E2-2KA as an effective solution to improve performance when they need to upgrade their equipment or create new systems. The servo motor demonstrates superior performance in metal cutting along with plastic injection molding and automotive assembly lines because its power and speed operations work together with responsive dynamics. Together with Kollmorgen motion controllers the servo motor enhances efficiency that allows increased production speed with reduced energy usage providing a cost-effective choice for contemporary manufacturing operations.
