Product Description:

The MSK100C-0300-NN-M1-LG2-NNNN is a synchronous servo motor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. In multi-axis machinery, this motor converts electrical drive commands into rotary motion that can be regulated in speed and position, making it a core actuator for packaging lines, printing presses, and material-handling gantries. Its integrated feedback and holding brake allow the connected drive controller to execute precise moves and maintain axis position when power is removed. This combination supports controlled starts, repeatable stopping behavior, and stable motion on vertical or indexing axes.

The motor uses a size 100 housing with frame length C and winding code 0300, which gives this build the electromagnetic cross-section and continuous torque capability intended for demanding servo duty. A left-side power connector feeds the stator, and a plain shaft couples directly to the load without keys. Position feedback is delivered through a Hiperface optical encoder that provides 128 signal periods, enabling fine speed control and accurate position tracking during commanded moves. The electrically released holding brake supplies 70 Nm of static torque so suspended or vertical loads can remain secured when drive power is removed. The motor has an IP65 enclosure that resists dust and low-pressure water jets.

Heat is removed by natural convection, so external fans are unnecessary when the ambient temperature stays within 0–40 °C. The motor windings use insulation class 155, which supports the thermal load created during repeated acceleration, deceleration, and holding phases. Absolute position is retained across power cycles because the encoder uses a multiturn absolute system, so homing is not required after restart. This feedback arrangement helps the drive recover axis position immediately after control power returns and supports coordinated motion on machines that cannot tolerate reference moves.
