Product Description:

The MSK100C-0300-NN-M2-BG2-RNNN is a synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. In automated machinery, it converts controlled AC drive power into precise rotary motion, supporting demanding positioning and speed regulation tasks on CNC axes, packaging equipment, and handling systems. This model uses winding code 0300, comes in size 100 with length code C, and features increased concentricity construction that minimizes runout for repeatable mechanical tracking. It is suited for machine sections where smooth motion and predictable shaft behavior are needed during indexing, feeding, and synchronized transfer tasks.

Heat generated in operation is removed by natural convection, eliminating the need for external fans or liquid circuits and allowing cabinet installation without external cooling hardware. The housing carries an IP65 rating, so internal components remain isolated from production dust and low-pressure water jets. Position information is supplied through an optical encoder that communicates over the EnDat2.1 digital interface; its scan head resolves 2048 signal periods per mechanical revolution, giving high interpolation capability to the drive controller. A plain shaft output simplifies alignment with couplings and belt pulleys, and the power connector is positioned on the B-side of the stator to support straightforward cable routing in multi-axis installations.

The servomotor includes an electrically released brake that provides 70 Nm of static holding torque, preventing axis movement during shutdowns or emergency stops without additional clamping devices. Its encoder stores position data over multiple rotations with multiturn absolute feedback, so the control system can retain axis position after power cycles. Class 155 insulation tolerates elevated winding temperatures while maintaining dielectric strength, and reliable service is specified for ambient conditions from 0–40 °C.
