Product Description:

The MSK030B-0900-NN-S1-UG0-NSNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. As a compact 030-frame unit with length code B, it converts electrical power from a drive controller into precise rotary motion for positioning axes, pick-and-place modules, and other high-repeatability automation tasks on factory floors. The motor integrates easily into sealed machines because its stator winding and feedback devices are packaged as one assembly, which helps reduce external wiring and supports accurate closed-loop control. This layout also helps machine builders fit the motor into compact axis assemblies where installation space is limited.

Thermal energy is removed through natural convection, so no external fan or liquid circuit is required. A die-cast housing and radial gasket system give the enclosure a protection rating of IP65, blocking dust ingress and low-pressure water jets encountered in typical production cells. Position feedback is handled by a Hiperface optical encoder that provides 128 signal periods per mechanical revolution. The rotatable 240° encoder connector allows the cable outlet to be aligned after the motor is fixed in place. The single-turn encoder design supports standard servo control tasks without the added complexity of multi-turn position storage.

The mechanical interface uses a plain shaft without a keyway, which supports backlash-free clamp couplings in servo modules used in both standard and explosion-protected zones under the motor’s dual-purpose design. Continuous duty can be maintained across the ambient range of 0–40 °C without derating, provided that airflow around the housing remains unobstructed. For holding functions, the system must rely on external means because the motor is shipped without a holding brake. Class 155 insulation supports high thermal endurance during continuous operation, and winding code 0900 indicates the electrical characteristics that must match the connected drive controller. The motor is suited for applications that need compact dimensions, accurate feedback, and stable operation over repeated motion cycles.
