Product Description:

The MSK071C-0450-NN-S1-UG0-NSNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As a compact servo actuator, it converts drive-controller output into precisely regulated rotary motion for positioning tables, packaging axes, or pick-and-place joints in industrial automation. The motor falls under the 071 frame size and C length class, giving it a mechanical envelope suited to medium-torque tasks while keeping installation straightforward inside sealed or pressurized machine compartments. It is intended for applications that require consistent response during repeated starts, stops, and short positioning moves.

Heat generated in operation is removed through natural convection, so machine builders do not need external blowers or coolant circuits. The feedback plug uses a rotatable 240° connector, which lets the cable exit be oriented away from tight panel walls. An optical encoder that communicates by the Hiperface protocol supplies absolute position data each cycle. Its base resolution is 128 signal periods, which the drive interpolates for fine velocity and position loops. A plain shaft without a keyway minimizes runout error and is typically coupled by a backlash-free clamping hub.

The housing has an IP65 rating that blocks dust ingress and low-pressure water jets, which suits washdown or paint-line zones. Insulation class 155 supports winding temperatures associated with cyclic acceleration without premature varnish aging. Continuous service is specified for ambient temperatures from 0 to 40 °C, which suits many enclosed machine spaces without torque derating. The stator uses winding code 0450, which matches the resistance and inductance values used by the MSK drive libraries. The motor uses optical single-turn feedback, operates without a holding brake, and is certified for both standard and explosion-protected installations.
