Product Description:
The MSM115-34-404-E2-2KA is a brushless servo motor produced by Kollmorgen for the MSM Brushless Servo Motors series. This compact unit converts electrical power into controlled mechanical torque. It supports precise positioning, velocity regulation, and rapid indexing on packaging, material-handling, and general motion axes in industrial automation.
The motor delivers a continuous shaft output of 3.8 Nm and can reach its nominal speed of 4000 rpm when supplied from the series’ 460-volt winding. During acceleration or shock loading, it can withstand a peak current of 15.6 A, enabling a momentary output of up to 12 Nm before thermal limits intervene. A torque constant of 0.95 Nm/A relates drive current directly to developed torque, simplifying current-mode control. Stall current is limited to 4.5 A peak. The 32.0 mH phase inductance smooths current transients, while the 8.4 Ω winding resistance determines copper losses. A 2,000-line incremental encoder reports the rotor position to the controller, providing high-resolution feedback for servo control loops.
The back electromotive force is 115 V/KRPM, so the drive must tolerate the voltage generated during full-speed regeneration. The holding brake engages at 24 VDC, keeping vertical or suspended loads stationary when motor power is removed. Rotational responsiveness is aided by a rotor inertia of 0.00093 kg-m² with the brake installed, balancing quick acceleration against stability. A shaft with a diameter of 19 mm and an M6 × 1.0 mm threaded end simplifies coupling to gearheads or pulleys. The motor has a mass of 7.7 kg, which must be considered when selecting mounting hardware and support structures. Its insulation system is suitable for standard industrial power applications.
