Product Description:

The MSK101C-0300-NN-S1-BG2-NNNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. In automated machinery, it works with a compatible Rexroth drive to convert electrical input into controlled rotary motion for indexing tables, gantry axes, and material-handling equipment. This layout suits machines that need precise starts, stops, and repeatable speed regulation across frequent cycle changes. The motor combines integrated feedback with a holding brake, so one housing can support closed-loop motion control and secure load holding when the axis is at rest.

The housing is rated IP65, which helps protect internal components against dust and low-pressure water jets. Its holding brake provides 70 Nm of static torque for vertical or suspended axes when drive power is removed. Position data is transmitted through Hiperface, and the optical system provides 128 signal periods per revolution so the drive can calculate fine angular movement. That feedback arrangement supports accurate commutation and position control without a separate external sensor package. Winding code 0300 matches the motor's electrical characteristics to compatible 300 V-class converters and supports stable current control during dynamic motion.

Heat is removed by natural convection, so the motor relies on free airflow and is intended for ambient temperatures from 0 to 40 °C. Because cooling is passive, no auxiliary fan or liquid circuit is required at the motor body. The output uses a plain shaft, which suits couplings for gearheads or belt-driven mechanisms. Insulation class 155 supports the thermal demands of continuous servo operation, while the size 101 and length C housing provide the mechanical envelope for this motor variant. Power cabling exits on the B-side connector, and the single-turn optical encoder supplies absolute position data immediately after power-up.
