Product Description:

The MSK100B-0300-NN-M1-RG0-NNNN is a synchronous servomotor built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It converts controlled drive current into precise rotary motion for positioning, feeding, and forming tasks in automated equipment. Its closed-loop design supports repeatable motion over long duty cycles, and integrated feedback lets the connected drive monitor rotor position and speed in real time. In automated lines, this response is useful for indexing tables, feed rollers, and transfer axes that start and stop frequently.

Heat is removed through natural convection, so the housing should be mounted where ambient airflow can pass freely, and no external fan or liquid circuit is required. Position data reach the drive over the Hiperface interface, and the encoder delivers 128 signal periods per revolution for commutation and velocity feedback. The encoder uses an optical measuring principle, which avoids magnetic hysteresis and helps keep resolution stable across temperature changes. Passive cooling also keeps the external motor shape uncomplicated and avoids extra blower connections. The motor is supplied without a holding brake, so any stationary load must be secured by drive torque or an external mechanical restraint.

The motor uses motor size 100, which provides a flange pattern and shaft center height suited to medium-power machine assemblies. Power enters through a right-side connector, which can help keep cable routing clear of adjacent modules in dense multi-axis layouts. A plain shaft works with clamp couplings to minimize backlash, and the encoder includes multi-turn absolute storage so the axis position remains available after power is restored. This arrangement is useful where space around the coupling and cable entry is limited. The B-length housing balances torque capability with installation depth, and winding code 0300 indicates the electrical characteristics expected by compatible drives.
