Product Description:

The MSK101E-0300-NN-M1-RG0-NNNN is an IndraDyn S synchronous servo motor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It converts controlled electrical input from a drive controller into regulated mechanical torque for positioning and velocity tasks in automated machinery and handling equipment. The motor is suited for precision axis service where repeatable motion, steady torque delivery, and accurate response to changing speed or position commands are required.

This model is cooled by natural convection, so heat leaves the housing through ambient airflow rather than forced fans or liquid circuits. Position feedback is delivered through a Hiperface interface that carries configuration data and real-time angle information to the drive. Inside the encoder, an optical scanning system generates 128 signal periods per mechanical revolution, and the multi-turn counter tracks rotation beyond one turn, so the feedback device is a multi-turn absolute encoder. The sensing principle is optical, which supplies high resolution without magnetic hysteresis and supports accurate closed-loop control during slow creep movements or fine incremental steps.

The motor is supplied without a holding brake, so standstill holding must be provided by drive torque or an external clamp. A housing protection rating of IP65 permits installation in dusty areas or washdown zones when paired with sealed connectors, and continuous operation is specified for ambient temperatures from 0–40 °C. Mechanical output is transmitted through a plain shaft, simplifying coupling with backlash-free clamping hubs, while right-side power terminations help route cables where several motors share a common tray. The unit uses thermal class 155 insulation and follows the standard design designation, with motor size 101, length E, and winding code 0300 setting the physical envelope and matching the motor to medium-to-high inertia loads.
