Product Description:

The MSK050B-0600-NN-S2-UP0-RNNN is an AC servomotor built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As a compact rotary drive unit, it supplies precise torque and position feedback for axes in packaging machines, pick-and-place gantries, and other automated stations. Its stator-mounted encoder enables closed-loop control, allowing the drive to maintain commanded motion profiles during indexing, positioning, and repeated start-stop operation in industrial automation cells.

This motor is cooled by natural convection, so heat is removed through the housing fins without forced airflow, which is useful where external fans are not available. The windings follow code 0600, which corresponds to the electrical resistance and inductance values expected by the matching IndraDrive controller. Position data are delivered through the optical EnDat sensor stack: the rear connector is rotatable through 240°, allowing the cable exit to be adjusted for different mounting directions, while the interface itself is EnDat2.1 for bidirectional digital communication. Within the glass scale, the read head generates 2048 signal periods per mechanical revolution, and the optical single-turn system reports absolute position within one turn without relying on battery-backed memory. This arrangement lets the drive receive position information immediately after power-up and maintain accurate feedback during short cyclic moves.

The mechanical outline follows size code 050 and length class B, giving a compact frame that fits standard MSK mounting flanges. Torque is transmitted through a shaft with keyway, so couplings or pulleys can transfer load without depending on friction alone. The motor is supplied without a holding brake, so vertical or static loads must be secured by external means or by drive torque. Increased concentricity helps reduce runout during rotation, which supports stable motion at rated speed. The single-turn optical encoder also supports smooth velocity control during rapid direction changes.
