Product Description:

Bosch Rexroth Indramat manufactures the MSK101C-0202-NN-S3-FB0-NPNN within the MSK IndraDyn S Synchronous Motors series. The unit is an IndraDyn S synchronous servomotor for precise rotary positioning and speed regulation. It is intended for packaging lines, machining centers, and pick-and-place stations where predictable dynamic behavior is required.

The motor uses frame size 101, giving it the diameter and bolt circle needed for medium-torque axes in multi-axis machines. Its stator carries winding code 0202, a pattern that sets the torque constant and current demand matched to IndraDrive controllers. Heat is removed only by natural convection, so no external fan or liquid circuit is needed, which simplifies cabinet airflow design. Power and feedback conductors terminate in a terminal box, allowing rigid metal-conduit connections and field reversal of cable entry. Rotor position is reported through a Hiperface interface; the integrated encoder generates 16 signal periods per revolution, permitting fine interpolation for smooth velocity loops.

The mechanical interface uses a B5 flange assembly, giving a pilot diameter and threaded holes that seat directly against gearbox or machine plates without additional brackets. Inside the encoder, a capacitive scanning method tolerates dust and oil better than optical discs, and its single-turn format provides absolute angle data for one revolution, which is adequate for positioning tasks that include homing routines during power-up. The motor is supplied without a holding brake, so static load retention must be handled by the drive or an external brake on vertical axes. A length C housing balances torque density with overall weight, and the terminal box orientation aligns with the flange face, reducing bend stress on cables when the servomotor is mounted in tight enclosures.
