Product Description:

The MSK070E-0300-NN-S1-UG0-NNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat and supplied through the MSK IndraDyn S Synchronous Motors series. The unit delivers closed-loop torque and position control for packaging stations, gantry modules, and articulated robot joints. It is intended for applications where compact size, high dynamic response, and electronic feedback are required to coordinate multiple motion axes in industrial automation.

The motor is cooled by natural convection, so enclosure airflow alone removes heat without external blowers or liquid circuits. Position feedback is exchanged over the Hiperface interface, allowing the drive to read both absolute angle and incremental counts on one hybrid link. Inside the feedback assembly, an optical disc provides 128 signal periods, which supports tight velocity loops and accurate homing. The sensing method is optical, meaning light-based encoder elements detect shaft rotation without mechanical contact and reduce wear. A single-turn code wheel is fitted, so the motor reports absolute position within one mechanical revolution for applications that do not exceed 360 degrees before re-indexing.

The encoder housing includes a 240° rotatable connector, which allows flexible plug orientation around nearby obstructions while keeping cable bend radii within limits. Output torque is transmitted through a plain shaft, a geometry that mates with keyed or clamp couplings when backlash must be minimized. The stator stack corresponds to size 070, and the overall length is the E variant, balancing inertia against continuous torque. Coil characteristics follow winding code 0300, which matches the motor’s electrical values to compatible IndraDrive controllers. The motor is built to the standard design level and is supplied without a holding brake.
