Product Description:

The MSK101D-0202-NN-S3-FB0-NPNN synchronous servomotor is produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. As part of an electric drive system, it transforms controlled three-phase power from an IndraDrive inverter into rotary motion for positioning tables, feeders, and handling modules in automated machinery. The motor’s closed-loop feedback supports accurate speed and torque control, making it suitable for applications that require repeatable motion under varying loads. Because rotor position is continuously reported to the drive, the system can correct speed deviations quickly during starts, stops, and changing process demands.

Power and sensor conductors terminate inside a terminal box, allowing stiff armored cables to connect without placing strain on the machine frame. Heat produced during operation is removed by natural convection, so installation clearances must support unobstructed airflow instead of external cooling devices. A B5 flange assembly centers the motor on the driven machine element and helps maintain alignment at the coupling interface. Position data travels over the Hiperface serial bus, so the connected drive can exchange feedback data through a compact cable set. Internally, the feedback element provides 16 signal periods per mechanical turn, and controller interpolation converts that pattern into the finer values used for commutation and speed regulation.

The motor uses a capacitive measuring principle, which is less sensitive to oil mist and light dust than optical sensing methods. Feedback is single-turn, so the absolute position repeats after one full revolution and multi-turn tracking must be maintained by the drive or the application controller. Frame size 101 gives the motor a housing suited to medium-inertia axes where stable torque and rigid mounting are required. Magnetic behavior follows winding code 0202, matching the current and voltage characteristics expected by 400 V class inverters. The motor has length D and is supplied without a holding brake, so a vertical or suspended load needs another method of retention when power is removed.
