Product Description:
Bosch Rexroth Indramat manufactures the MSK101C-0300-NN-S2-AG2-RNNN as part of the MSK IndraDyn S Synchronous Motors series. The unit is an IndraDyn S synchronous servomotor intended to deliver regulated torque and velocity to automated axes in assembly cells, material-handling gantries, and similar industrial motion platforms. By integrating a high-resolution feedback device and an electrically released brake, it supports precise positioning and safe load retention within multi-axis drive systems in modern, high-cycle production lines. Its servo design allows the motor to respond quickly to command changes, which is useful in applications that alternate between rapid movement, controlled acceleration, and repeatable stopping.
The motor relies on natural convection cooling, so adequate airflow around the housing must be maintained for continuous duty. An electrically released holding brake supplies 70 Nm of static torque to secure vertical or indexing loads when the drive is de-energized. The housing carries an IP65 rating, which helps keep dust and low-pressure water jets away from internal components. Position feedback is transferred through an EnDat2.1 digital interface, and its optical scale provides 2048 signal periods per mechanical revolution for fine speed and position control.
The feedback system uses optical scanning in a single-turn format, which suits applications that reference the axis during startup rather than storing multiple revolutions of absolute position. A plain shaft with increased concentricity reduces runout and simplifies coupling to backlash-free hubs. Continuous operation is specified within an ambient range of 0-40 °C, and the Class 155 insulation system is matched to the thermal demands associated with winding code 0300. Frame size 101 with length C gives the motor a medium-power footprint, and the power connector on the A-side supports straightforward cable routing in compact machine layouts.
