Product Description:

The MSK100B-0450-NN-M1-AP1-NNNN is a synchronous servomotor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It is intended to translate drive controller currents into precise rotary motion for indexing tables, gantry axes, and other industrial automation points that demand high positional repeatability. A standard housing, a natural convection cooling path, and a keyed shaft support direct mechanical coupling while keeping the motor compact enough for multi-axis assemblies. This layout suits installations where accurate positioning and stable torque response are required over repeated operating cycles.

The motor relies on natural convection for heat dissipation, so airflow around the frame must be maintained rather than adding external blowers. Feedback is supplied through a Hiperface interface that carries position and parameter data between the encoder and the drive. That encoder generates 128 signal periods per mechanical revolution, and its optical scanning principle supports high interpolation accuracy without magnetic drift. Because the scanning disk stores absolute track information, the unit provides multi-turn absolute feedback, which allows the drive to retain position information after a power cycle. This feedback arrangement supports precise axis control during speed changes and positioning moves.

An electrically released holding brake supplies 32 Nm of torque to keep loads secure during shutdown or safety stops. The frame size is 100, and the length designation B gives the motor a longer active stack for higher continuous torque than shorter versions in the same platform. Power and signal conductors are routed on the A-side of the housing, which helps keep cable routing orderly when several motors are mounted in sequence. A keyed output shaft transmits torque through positive engagement rather than relying only on friction. The brake also helps prevent unintended axis movement when the drive is disabled or the machine is at standstill.
