Product Description:

The MSK050C-0300-NN-M1-UP1-NNNN is a servo motor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. As a rotary actuator, it converts electrical energy from the drive into controlled mechanical motion for positioning and velocity tasks in industrial automation cells such as gantry axes, packaging machines, and material-handling lines. Its integrated absolute encoder and built-in holding brake allow the drive system to capture position data and secure loads when power is removed. That combination supports repeatable starts and controlled stops on axes that must return to a known position after power cycling.

This model relies on passive cooling by natural convection, so enclosure airflow must remain unobstructed to maintain thermal limits during continuous duty. Feedback is transmitted through the Hiperface interface, and the optical reader resolves the motor shaft into 128 signal periods; with internal interpolation, the controller can compute fine position steps for smooth servo regulation. The electrically released brake provides 6 Nm of static torque, permitting vertical or indexing axes to hold position without drive current. Power is transferred through a shaft with a keyway, giving a positive mechanical lock to couplings or pulleys while preserving concentricity. The motor length coded C offers moderate stack height, balancing torque output with a compact footprint.

Wiring convenience is improved because the encoder plug is rotatable through 240°, letting the cable be routed toward the nearest raceway without twisting the conductors. Inside the feedback unit, sensing is based on optical scanning, and the encoder uses multi-turn absolute position tracking to keep position values after power loss. The electromagnetic circuit follows winding code 0300, matching resistance and inductance to the IndraDrive control family. The motor uses frame size 050, which corresponds to the stator diameter and flange pattern common to smaller MSK motors. This layout keeps the unit compact while still supporting closed-loop motion control in space-limited machine sections.
