Product Description:

The MSK030C-0900-NN-S3-UG0-NNNN is a synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. The unit couples directly to a servo drive and converts controlled three-phase power into precise rotary motion while integrated feedback returns position data to the control loop. This arrangement supports compact pick-and-place axes, metering stations, and labeling heads that require accurate starts, stops, and short indexing moves. Its compact format also fits machine sections where rapid response and stable positioning are needed without adding bulky external hardware. It is well suited to light, repetitive duty cycles in packaging and small transfer mechanisms.

Thermal energy is removed through natural convection, allowing installation without external fans or liquid circuits. Feedback wiring enters through a rotatable 240° connector that mates with a Hiperface interface, so a single hybrid cable can carry power, data, and supply voltage. Inside the encoder, capacitive sensing electronics detect graduations that produce 16 signal periods per mechanical turn, and the drive interpolates these signals for fine position control. Because the scanning system is single-turn, the absolute position repeats after one revolution, which suits short-stroke rotary applications and simplifies startup on axes that do not require multi-turn tracking. The rotatable connector also helps route the cable in tight spaces and reduces bending stress near the housing.

Mechanical output is provided by a plain shaft, so couplings or pulleys seat directly without keyways. The assembly ships without a holding brake, so static load retention must be provided by the drive or by external clamping hardware. Frame designation 030 identifies the small stator diameter, which helps keep mass and inertia low for quick acceleration in confined spaces. Winding code 0900 indicates the coil arrangement and electrical values matched to the inverter for rated current, and the motor uses length code C for a longer active stack without changing the flange geometry. The longer active stack increases available torque within the same flange size.
