Product Description:

The MSK101D-0450-NN-M1-BG3-NNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As a compact rotary actuator, it converts drive-controlled electrical power into precise mechanical motion for positioning tables, gantries, and processing spindles in automated equipment. The unit integrates into closed-loop axes where accurate speed and position regulation are required. Its operating role is focused on controlled rotary motion in systems that must respond consistently to changing commands and load conditions.

Thermal management is handled exclusively through natural convection, allowing installation without external blowers when normal ambient airflow is available. Position feedback is generated by an optical encoder that communicates through the Hiperface interface. Its track contains 128 signal periods per revolution, allowing the controller to process fine angular changes for smooth torque production. An electrically released holding brake rated at 120 Nm locks the rotor during shutdown or emergency stops to help prevent load drift. The cast-aluminum housing has an IP65 protection rating, which blocks dust and guards against water jets during machine operation.

Long-term repeatability is supported by the encoder’s multiturn absolute capability, which retains shaft revolution information after power loss and removes the need for a reference move at startup. The motor uses frame size 101 with length code D, giving it a substantial torque capacity within a compact industrial housing. Its power connector is located on side B to simplify cable routing in confined installations, and the plain shaft supports backlash-free clamp couplings. Reliable operation is specified within an ambient range of 0–40 °C, while insulation class 155 supports the winding system during dynamic duty. The standard construction and winding code 0450 establish the electrical characteristics used by the matching drive.
