Product Description:
The MSK100C-0300-NN-S2-BG0-RNNN is an IndraDyn S synchronous servomotor designed by Bosch Rexroth Indramat and supplied within the MSK IndraDyn S Synchronous Motors series. As a rotary actuator, it converts controlled electrical input from a drive into precise mechanical torque for positioning, contouring, and speed-control tasks in industrial automation lines. The motor integrates electronic feedback and mechanical features that support tight loop control on packaging machines, material-handling gantries, and forming equipment. Its feedback system allows the paired drive to monitor rotor position continuously and react quickly to changing load conditions during motion.
Heat dissipation relies on natural convection, so the housing must be mounted where ambient airflow can remove losses without forced cooling. The enclosure carries an IP65 rating, which keeps out dust and resists low-pressure water jets in exposed machine locations. Position feedback is provided through a single-turn encoder that uses the EnDat2.1 interface, allowing digital position data and configuration signals to travel through one cable. The feedback system provides 2048 signal periods, and the optical sensing principle helps maintain accurate resolution even at low shaft speeds. The motor also uses winding code 0300, while the increased concentricity design improves running accuracy at the shaft and coupling interface.
The insulation system is class 155, and the permitted ambient range of 0–40 °C allows continuous operation in typical indoor industrial conditions. Because the unit is supplied without a holding brake, a vertical axis requires an external braking method or drive-applied holding torque when power is removed. The plain shaft accepts friction-fit couplings and similar hub arrangements, while the B-side power connector can simplify cable routing on machines with limited installation space. Size 100 and length code C place the motor in a medium frame suited to precise servo duties without requiring liquid cooling.
