Product Description:
The MSM115-62-404-S-0KA is a brushless servo motor produced by Kollmorgen within the MSM Brushless Servo Motors series. Designed for closed-loop motion platforms, the unit converts electrical energy into precisely controlled mechanical torque, allowing packaging lines, pick-and-place robots, and indexing tables to run with repeatable accuracy and quick cycle times. The motor pairs with Kollmorgen digital drives that supply sinusoidal commutation and feedback, so position and velocity commands are executed without mechanical overshoot.
Under continuous duty, the motor delivers 7.0 Nm while maintaining its temperature within insulation limits. A rated shaft speed of 4000 rpm suits production machinery that must track rapid acceleration profiles yet hold steady at the set point. The stator is wound for 460 V AC, letting it connect to North American three-phase mains without step-up transformers, and phase sequencing is optimized for 6 electrically symmetric poles that reduce cogging at low speed. Drive controllers may draw up to 26.9 A during full-load transitions, but steady-state torque is supported by a stall current of 7.8 A and a copper winding resistance of 3.4 Ω that determines I²R heating. Because no brake is fitted, dynamic holding force must come from the drive or external clamping devices.
For overload peaks such as cam indexing, the rotor can withstand 22 Nm for short intervals, aided by a low reflected inertia of 0.0010 kg·m² that minimizes the energy required for acceleration. Electromagnetic conversion efficiency is indicated by a torque constant of 0.99 Nm/A, so each ampere supplied by the inverter adds a predictable amount of torque. A back-EMF constant of 120 V/KRPM supports DC-bus sizing for regenerative events. Mechanical coupling uses a smooth shaft that measures 19 mm in diameter and is tapped with an M6 × 1.0 mm thread for puller or encoder hardware.
