Product Description:

Bosch Rexroth Indramat manufactures the MSK071C-0200-NN-S1-UP1-NNNN for the MSK IndraDyn S Synchronous Motors series. Delivered as an IndraDyn S synchronous servomotor, it is intended for closed-loop motion axes in CNC machinery, printing presses, and automated assembly cells where accurate speed and position control are critical. The motor follows the standard mechanical and electrical design, giving machine builders a familiar mounting interface. This arrangement supports servo applications in which the drive must correct load changes quickly during motion.

The unit is cooled by natural convection, so surrounding airflow determines its continuous output and no external fan is required. Inside the stator, winding code 0200 identifies the winding layout and impedance values used for this frame size. Position feedback is generated by an optical encoder that communicates through the Hiperface digital interface and resolves motion over 128 signal periods, allowing fine interpolation in the drive controller. For static axis locking or emergency stops, an electrically released holding brake provides 23 Nm of torque. Mechanical power is transmitted through a shaft with keyway, which allows a positive connection to couplings, pulleys, or gear inputs.

Cable routing is simplified by the rotatable 240° connector on the encoder housing, allowing the feedback lead to exit in the preferred direction without twisting the motor body. The encoder operates in a single-turn configuration and returns an absolute position within one mechanical revolution, which suits many translational and rotary axes that also use an external homing reference. The connector position also helps when cable space is limited near guards, machine frames, or adjacent axes. The motor has a length C housing and a size 071 frame. These dimensions determine the flange size, stack height, and inertia used when matching the motor to the driven load.
