Product Description:

The MSK100B-0400-NN-S1-AG2-NNNN is an IndraDyn S synchronous servo motor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. As a rotary actuator, the unit converts drive current from a controller into precisely regulated shaft motion for packaging, printing, material-handling equipment, and other automated machinery that depends on accurate servo response. Integrated feedback and a built-in brake allow the motor to maintain accurate position and controlled acceleration during repetitive cycles, making it suitable for closed-loop automation axes that demand high repeatability, stable stopping behavior, and minimal maintenance.

Cooling is provided by natural convection, so the frame must be mounted where ambient airflow can carry away heat without external blowers. The unit follows a standard mechanical design that uses common mounting geometry across the series and supports straightforward installation with matching hardware. A Hiperface interface links the motor feedback to compatible drives, while optical scanning inside the encoder yields 128 signal periods per revolution. The sensing element uses optical technology, and its measurement range is limited to one revolution because the encoder is a single-turn device. These characteristics provide absolute position data with fine incremental interpolation, allowing tight speed loops, homing, and reliable position tracking after power-up. Winding code 0400 indicates the coil resistance and inductance used by the connected drive, and electrical power enters from the A-side connector to simplify cable routing inside enclosures.

For load-holding demands, an electrically released brake delivers 70 Nm of static torque to prevent shaft movement whenever control power is removed. The housing uses length code B and size code 100, giving the motor a balanced ratio of inertia to continuous torque in medium-frame machinery and providing a compact footprint for general automation axes. Torque is transmitted through a plain shaft, which suits backlash-free couplings and belt pulleys. This shaft style is commonly paired with clamp couplings or pulleys where a smooth mating surface is preferred.
