Product Description:
The MSM115-34-404-M-0KA-240N is a brushless servo motor built by Kollmorgen within the MSM Brushless Servo Motors series. As a compact rotary actuator, it converts drive current into precisely metered torque and speed for indexing tables, pick-and-place arms, or other tightly controlled motion axes in industrial automation. Six poles and a multi-turn high-resolution feedback device let the controller close position loops with high granularity even after power cycling.
Its continuous torque capability of 3.8 Nm is the load the shaft can sustain indefinitely without excessive heating. When short bursts are needed, the motor delivers up to 12 Nm of peak torque, providing headroom for acceleration or overcoming static friction. Rated mechanical speed is 4000 rpm, so the rotor can turn four thousand times per minute while maintaining servo accuracy. To reach these operating points, the drive may supply as much as 15.6 A Peak, while the locked-rotor stall current is 4.5 A peak. A 460 V voltage-class winding aligns with common DC-bus levels in multi-axis cabinets, and the electromagnetic conversion factor is 0.95 Nm/A, simplifying current-based torque calculations.
Dynamic response is influenced by the rotor’s mass moment; at 0.00057 kg-m², it resists acceleration only slightly, supporting fast cycle commands. The winding inductance of 32.0 mH filters current ripple, while the 8.4 ohm resistance sets copper losses that must be modeled thermally. Back EMF is characterized by a voltage constant of 115 V/KRPM, allowing predictive regeneration estimates during deceleration. Installation details include an M6 × 1.0 mm shaft thread with a 16 mm depth for secure attachment of couplings or pulleys. Overall mass is 6.6 kg, light enough for gantry end-effectors yet heavy enough to damp vibration.
