Product Description:

The MSK100B-0300-NN-M1-BP1-NNNN is a synchronous servo motor produced by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. It supplies closed-loop rotary motion for automated machining centers, pick-and-place axes, and similar positioning duties. Internal feedback allows the drive controller to command speed and angle precisely, while an electrically released holding brake secures the shaft during power-off states.

Thermal management is handled by natural convection, so the housing dissipates heat without external fans or liquid circuits. A Hiperface interface carries feedback signals from the encoder to the drive, supporting both position data and electronic nameplate information. The measuring system resolves rotor movement into 128 signal periods, and its optical scanning principle provides high repeatability because it is insensitive to magnetic stray fields. Position tracking is supported by a multiturn absolute design, allowing the controller to recover the exact shaft position after power loss without a homing cycle. The motor uses winding code 0300 and a standard mechanical design.

The electrically released brake produces 32 Nm of static torque, which is suitable for holding typical loads matched to the motor’s continuous rating. The motor has size 100 and a B length, giving a balance between inertia and peak torque for mid-range axes. Power enters on the B-side of the stator housing, so cable routing can follow conveyors or machine frames placed on that side. Output motion is transmitted through a shaft with keyway, which accepts standard keyed couplings and helps prevent slippage during cyclic reversing. The standard design does not include special coatings or added sealing features beyond the normal IP protection used across the series.
