Product Description:

The MSK100B-0300-NN-S1-LP0-NNNN is a synchronous servo motor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It converts drive power from the connected controller into precise rotary motion for positioning and process control tasks in automated machinery that depends on repeatable speed and position control. By combining a 100 frame size with the B-length stator, the motor provides a balance between torque density and overall package length, making it suitable for mounting in medium-power axes where space is limited. This layout supports compact machine designs without sacrificing stable servo performance.

This model relies on natural convection to remove internally generated heat, so no auxiliary fan or liquid circuit is required. An enclosure rating of IP65 protects internal components against dust ingress and water jets during normal plant washdowns. Position feedback is transmitted over the Hiperface interface, and the optical scanning head resolves the code disk into 128 signal periods, enabling tight speed loops at the drive. Because the technology is optical, the encoder maintains accuracy without magnetic drift. Power enters through a left-side connector that simplifies cable routing when the motor is mounted on the right wall of a cabinet or gantry. The side-mounted connection also helps keep cable bends manageable in compact machine frames. The motor is delivered without a holding brake to keep weight and inertia low for highly dynamic cycles.

The feedback stack is of the single-turn type, providing absolute position within one revolution. This allows the controller to read rotor position immediately after startup without depending on incremental travel from a reference mark. Continuous operation is supported across 0–40 °C ambient, and the windings are insulated to class 155 so they tolerate elevated internal temperatures generated by the 0300 winding. The motor uses a standard design suited to packaging, handling, and light machining stations.
