Product Description:

The MSK100C-0450-NN-S1-BG2-NNNN is a synchronous servomotor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It converts electrical energy into controlled rotary motion for positioning and velocity tasks in automated machinery. The motor uses frame size 100 with length code C, placing it in the mid-range of the lineup. Its synchronous design supports closed-loop operation with a compatible drive, so torque and speed can respond quickly to changing load conditions.

Cooling is done by natural convection, which eliminates the need for external fans and relies on surface area and ambient airflow for heat dissipation. The integrated single-cable feedback line carries power and encoder data through a Hiperface interface, returning absolute position and motor-related data to the drive controller. Inside the encoder, an incremental track with 128 signal periods provides fine resolution per revolution before electronic interpolation. Because the scanning principle is optical, position detection resists magnetic stray fields and remains accurate across the rated speed range. Winding code 0450 indicates electrical characteristics matched to standard IndraDrive amplifiers.

The encoder operates in single-turn mode, reporting the absolute rotor angle within one revolution and simplifying homing routines. An electrically released brake supplies 70 Nm of holding torque to secure vertical axes when the DC bus is de-energized. The housing is sealed to IP65, which helps block dust ingress and water jets, and the motor is intended for continuous duty at ambient temperatures between 0–40 °C without derating. A plain shaft eases coupling to gearboxes or timing belts, while class 155 insulation supports winding temperatures up to 155 °C during dynamic motion cycles.
