Product Description:

The MSK100B-0400-NN-S1-AG0-NNNN is a synchronous servomotor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. The unit is intended for integration with Rexroth drive controllers, where it provides tightly regulated torque and speed for automated handling stations, printing presses, and material-forming equipment. By combining permanent-magnet excitation with digital feedback, the motor delivers rapid dynamic response for multi-axis positioning tasks. That response is useful on axes that must start, stop, and reverse direction with little delay during normal machine operation.

Cooling relies on natural convection, so heat is carried away by ambient air without fans, which reduces added electrical load and keeps the motor layout simple. The power terminations are arranged on the A-side, allowing cable routing to stay inside the machine footprint when the motor is mounted against a vertical panel. Mechanical output is delivered through a plain shaft, which mates with couplings or pulleys that use clamping or keyless hubs. Data exchange with the controller is handled via the Hiperface interface, and this bidirectional channel carries absolute position data for closed-loop operation. Inside the encoder, the disk yields 128 signal periods per revolution, giving the drive a detailed feedback signal for stable speed regulation.

The position sensor is configured as a single-turn device that reports angle within one revolution, while additional turn tracking can be handled by the external controller when required by the application. Its optical scanning method helps avoid the drift that can occur in magnetic systems and supports consistent feedback quality over time. The motor uses a motor size 100 frame with the mid-length B housing, giving a balanced inertia range for medium-throughput axes. Electrical matching to compatible inverters is indicated by winding code 0400, which corresponds to phase resistance and inductance values suited to this motor design. This electrical match supports responsive acceleration and controlled motion during repeated positioning cycles.
