Product Description:

The MSK071C-0200-NN-S2-UG0-RNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. This C-length, size 071 unit converts electrical energy into controlled rotary motion for high-precision positioning tasks in packaging machines, gantry systems, and material-handling axes. Its increased concentricity design minimizes radial runout, allowing direct coupling to precision gear stages or linear drives where exact shaft alignment is required. When used with a compatible drive, it supports accurate speed and position control during repetitive motion cycles. That makes the motor suitable for axes that require smooth response during indexing, feeding, and synchronized transfer.

Heat is removed by natural convection, so the installation must leave clearance around the frame for airflow rather than relying on fans. Feedback is handled through a rotatable 240° connector that carries the bidirectional EnDat2.1 signal to the drive controller. Inside the encoder, an optical scanning process resolves 2048 signal periods per revolution, and the single-turn format reports an absolute angle over one mechanical turn. A plain shaft simplifies mechanical integration because no keyway machining is present, which supports clamp or shrink couplings. Because the encoder provides an absolute position within one turn, the drive can establish rotor orientation immediately after startup. The rotatable connector also helps cable routing when the motor must be mounted in restricted machine spaces.

The motor is supplied without a holding brake, so any load holding must be accomplished electrically or through external locking devices. It is rated for operation between 0 to 40 °C, a range that helps preserve bearing grease life and magnetic properties during normal use. The housing is rated IP65, protecting internal components from dust ingress and low-pressure water jets. Class 155 insulation permits elevated winding temperatures during cyclic overloads while maintaining electrical integrity. The sealed housing and thermal class suit machines that operate near dust, spray, or repeated acceleration cycles. These features support reliable motion in equipment that requires precise positioning and steady thermal performance over long operating periods.
