Product Description:

The MSK071C-0302-NN-S1-UG0-NNNN is a synchronous servomotor from the MSK IndraDyn S Synchronous Motors series produced by Bosch Rexroth Indramat. Within automated machinery, this motor converts commanded drive current into precise rotary motion for axes that require high positional accuracy and fast response. Its synchronous operating principle allows the connected drive to regulate speed and position with quick correction of load changes. It uses a standard mechanical layout that supports direct coupling to gearboxes, ball screws, or timing belts in packaging, printing, and material-handling equipment.

The unit relies on natural convection, so heat is removed by surface airflow without an auxiliary fan. Feedback is routed through a 240° rotatable connector, which allows flexible cable orientation and simplifies cable routing. Position data reach the drive through the Hiperface interface, and the integrated encoder provides 128 signal periods per revolution to support stable velocity control. Because the scanning method is optical, the feedback signal remains precise during normal thermal variation. The encoder is a single-turn type, so absolute position is retained for one mechanical revolution.

The motor uses a plain shaft, which is suited to friction-locked couplings that minimize backlash. This shaft style is often selected where keyed joints are not required and where compact couplings are preferred. With a motor size of 071, its flange dimensions and bolt circle match other components in the series. The housing is supplied without a holding brake, so vertical loads must be secured by external hardware or by drive-generated holding torque when power is removed. The standard design uses motor length code C, giving a practical balance of peak torque capacity and overall weight for medium-inertia applications.
