Product Description:
The MSK100B-0400-NN-M1-BG1-NNNN belongs to the MSK IndraDyn S Synchronous Motors series from Bosch Rexroth Indramat. It is a synchronous servomotor for closed-loop industrial axes and provides position and speed control for packaging stations, metal-cutting tables, and material-handling gantries. When paired with a compatible drive, the motor converts commanded current into controlled rotary motion for indexing, feed, and positioning tasks. This operating profile suits equipment that requires stable response during acceleration, deceleration, and repeated cycle changes.
This model dissipates heat through natural convection, so no forced airflow or liquid circuit is required during operation in installations with adequate free air around the housing. Its frame is the compact size 100 with a B-length housing that balances torque density and installation depth in medium-size machine spaces. The electromagnetic package carries winding code 0400, which matches the stator's electrical values to compatible Rexroth drive controllers. A plain shaft exits the front end for coupling to suitable hubs or clamping elements, and power is routed through a connector on side B to keep the cable bundle away from linear guides or gearheads. The construction uses a standard design without additional sealing or stainless options.
On the feedback side, rotor position is reported by a Hiperface interface that transmits absolute angle data and diagnostic information to the drive. The optical scanner tracks an encoded disc with 128 signal periods, while the integrated memory retains turns through a multi-turn absolute mechanism, eliminating the need for homing after power loss or an unscheduled stop. Motion can be held at standstill by an electrically released brake rated at 32 Nm. The brake engages automatically whenever DC link voltage is removed, which helps keep the axis in place during power-off conditions and controlled machine stops.
