Product Description:

The MSK050C-0300-NN-S1-UG0-NSNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It is intended for precision positioning and velocity control in industrial automation lines, transforming drive inverter output into repeatable mechanical motion for pick-and-place axes, packaging stations, or small conveyor segments. The motor’s closed-loop feedback and sealed construction make it suitable for use inside machine frames and control cabinets where space is limited and reliable operation is required. Its compact servo design supports accurate motion in applications that depend on steady response during repeated start-stop cycles.

The housing carries a protection rating of IP65, so airborne dust and low-pressure water jets cannot reach internal components. Heat is removed through natural convection, allowing operation without fans or liquid cooling hardware. Winding code 0300 indicates resistance and inductance values that match Rexroth drive libraries, while a rotatable 240° connector lets the feedback cable exit in the preferred direction. Position data travel over the Hiperface interface, and the optical sensor produces 128 signal periods per revolution for smooth speed control. The encoder uses a single-turn architecture that provides an absolute position within one mechanical revolution, which suits axes that return to a reference point during normal operation. Class 155 insulation withstands the elevated winding temperatures that can occur during dynamic duty.

The frame size 050 with length code C yields a compact package that simplifies mounting on tight machinery layouts. A plain shaft permits direct coupling to gearheads or belt drives, and its gland works with the housing seal to help maintain enclosure integrity. Because the motor is supplied without a holding brake, static load locking must be achieved by mechanical means or drive torque. Ambient service limits of 0 to 40 °C fit standard shop environments, and the overall layout is well suited to small servo axes where installation space and cable routing must remain simple.
