Product Description:
The MSK030B-0900-NN-M1-BG1-NNNN belongs to the MSK IndraDyn S Synchronous Motors series produced by Bosch Rexroth Indramat. As a synchronous servo motor, it combines a permanent-magnet rotor with high-resolution feedback to drive precision axes in packaging machines, pick-and-place gantries, and other industrial automation equipment. Its compact 030 frame and B length fit tight mechanical envelopes while still delivering responsive torque, and the integrated brake can hold the load at standstill when the system is de-energized. This arrangement suits compact handling modules and short-travel positioning tasks where accurate motion and limited installation space are both important.
Heat is removed by natural convection, so no external fan or liquid circuit is required and the housing only needs unobstructed airflow around it. The stator winding uses code 0900, which indicates the electrical layout for this frame size. Feedback passes through the Hiperface interface, and the optical sensor delivers 128 signal periods per mechanical revolution for accurate position data. Because the transducer is multi-turn absolute, the motor can report shaft position across multiple turns after power is removed. That feedback supports commutation and position control without requiring a homing move at startup. A B-side power connector supports straightforward cable routing when drives are mounted below the axis, and the electrically released holding brake provides 1 Nm of static torque for load retention.
The die-cast housing carries a protection rating of IP65, sealing the windings and encoder against dust ingress and low-pressure water jets. Reliable operation is specified within 0 to 40 °C, which suits most indoor industrial installations. Class 155 insulation provides thermal margin during intermittent overloads and supports stable winding protection during demanding duty cycles. A plain shaft transmits torque without keyways, which helps reduce tolerance stack-up in precision couplings and supports accurate alignment in compact drive assemblies.
