Product Description:
The MSM215-319-304-E2-0KA is a brushless servo motor produced by Kollmorgen within the MSM Brushless Servo Motors series. Designed for positioning and velocity control in automated machinery, the unit converts drive current into shaft torque so that indexing tables, presses, or gantry axes can follow precise motion profiles generated by the controller. The motor uses six stator poles, while an optical encoder with 2,000 lines per revolution provides consistent feedback for closed-loop motion control.
At its continuous operating point, the motor supplies 36 Nm while turning at a rated speed of 3000 rpm. Electromagnetic coupling efficiency is characterized by a torque constant of 1.36 Nm/A, so drive current translates directly into predictable torque for precise loop tuning. The armature is wound for a 460 V class bus, and a voltage constant of 164 V/krpm indicates the back electromotive force that the inverter must overcome at speed. Electrical dynamics are shaped by a winding inductance of 10.6 mH and a winding resistance of 0.40 ohm; these values influence current rise time, drive sizing, and resistive heating. A keyway shaft simplifies rigid coupling to the driven equipment. The motor is supplied without a holding brake, so an external mechanism is required when a load must remain stationary after power is removed.
For transient moves, the motor can generate up to 100 Nm, allowing short bursts of torque to accelerate heavy loads. The drive must accommodate a peak current of 93.3 A, while the specified stall current is 28.7 A. System inertia matching benefits from a rotor moment of inertia of 0.0108 kg·m², which helps determine the acceleration response of the connected axis. The motor has a total mass of 33 kg, and the mounting structure must support this weight along with the dynamic forces produced during operation. Proper shaft alignment helps prevent excessive bearing loads when the motor is connected directly to a gearbox, pulley, or rigid coupling.
