Product Description:
Bosch Rexroth Indramat manufactures the MSK100C-0301-NN-M1-LG0-NSNN in the MSK IndraDyn S Synchronous Motors series. This synchronous servomotor delivers tightly regulated torque and velocity for automated packaging equipment, gantry axes, and material-handling stages. It is intended for applications that require repeatable positioning and stable speed control during frequent motion changes. Its response characteristics support axes that must accelerate, settle, and reverse direction without losing motion consistency.
The motor removes heat solely through natural convection, so no external air mover or liquid circuit is required in the enclosure. This cooling method keeps the motor self-contained and avoids the extra space needed for auxiliary cooling hardware. Its housing carries an IP65 rating, sealing the stator against dust ingress and low-pressure water jets that may occur during routine washdowns. A plain shaft is supplied, permitting backlash-free coupling with bushing hubs or shrink discs. Feedback and drive electronics communicate via the Hiperface serial interface, and the optical encoder resolves the rotor into 128 signal periods, giving the control loop fine incremental data. The 100 mm frame diameter and C length code set the motor envelope, while the 0301 winding is matched to the electrical values expected by the drive. The connector for phase conductors is located on the left side, which can simplify cable routing in cabinets arranged for right-hand service.
The position sensor retains its count over power cycles because it is a multi-turn absolute device, eliminating homing moves at startup. Stored position information helps the connected drive resume controlled motion without a reference search after an interruption. The unit is supplied without a holding brake, so static holding must be provided externally when the axis is stopped. Continuous operation is limited to ambient temperatures of 0–40 °C, and the windings use Class 155 insulation for the thermal system. This operating range suits indoor industrial installations that stay within normal room-temperature limits.
