Product Description:

The MSK101C-0301-NN-S1-BG0-NSNN is a rotary servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As a synchronous servomotor, it provides closed-loop torque and velocity control for automated axes in packaging, printing, and material-handling lines. The C-length frame and 101 size stator give the motor a medium mechanical envelope suited to mid-range continuous duty. That makes it suitable for servo axes that start and stop frequently, follow synchronized motion profiles, or maintain steady velocity through changing process loads.

The motor sheds heat by natural convection, so no external blower or liquid circuit is required. The housing is sealed to IP65, which helps keep dust and water jets away from internal windings and bearings. Continuous operation is permitted within an ambient range of 0–40 °C. The windings use class 155 insulation, which supports elevated internal temperatures during normal service. A plain shaft simplifies coupling to gearboxes or timing pulleys without a keyway, and the motor is supplied without a holding brake. Electrical feedback is routed through a Hiperface interface that carries position data to compatible IndraDrive controllers. Because cooling is passive, the motor can be installed where auxiliary fans or coolant routing are not preferred. Winding code 0301 identifies the electrical winding used in this model.

Position tracking is handled by an optical encoder with 128 signal periods per mechanical revolution. The feedback system is single-turn, so the absolute position reference resets after one revolution. It also allows the connected drive to interpolate the encoder signal for finer commanded position resolution during servo operation. Power conductors exit on the motor's B-side, which can simplify cable routing when the machine layout favors overhead or rearward cable runs. This arrangement supports commutation and position control through the drive while helping keep motor cables clear of nearby moving hardware.
