Product Description:
The Bosch Rexroth Indramat MSK100C-0300-NN-M1-BG0-NNNN is an IndraDyn S synchronous servo motor in the MSK IndraDyn S Synchronous Motors series. As a permanent-magnet AC unit, it is used in industrial automation to deliver closed-loop position and velocity control for packaging machines, metal-cutting axes, and material-handling gantries. The motor combines a compact 100-frame stator with integrated feedback electronics so it can connect directly to Rexroth drive controllers and deliver precise torque without the losses that can come from intermediate mechanical transmission components. This arrangement supports accurate motion on axes that must start, stop, and reverse repeatedly during operation.
The winding code 0300 indicates the turn count and conductor cross-section, matching the motor to medium-voltage, high-current drive inverters. Cooling is handled by natural convection, so heat is removed through the frame surface without fans or liquid circuits, and the housing requires free airflow around it. Position feedback comes from an optical multiturn encoder that provides 128 signal periods per revolution, and the encoder communicates over the Hiperface interface for bidirectional parameter exchange and automatic electronic nameplate detection. That feedback allows the drive to monitor rotor position over multiple revolutions and maintain stable velocity control as operating speeds change.
The mechanical side of the motor uses a plain shaft, allowing rigid coupling to gearboxes or ball screws without keyways that could introduce play. Power enters on the B-side, which routes the angled connector away from moving cables and keeps the encoder plug on the opposite face for service access. The length designation C increases the active stack while keeping the motor size 100 mounting pattern, which supports higher continuous torque in the same footprint. Because the unit is supplied without a holding brake, the application must provide external clamping or maintain drive torque when power is removed.
