Product Description:

The MSK101E-0450-NN-S1-BG0-NNNN is an IndraDyn S synchronous servo motor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. Intended as a compact rotary actuator, it delivers controlled torque and high-resolution position feedback to conveyors, gantries, and machining heads in automated production lines. The unit integrates into Rexroth drive platforms through its rear power connector and supports closed-loop motion where precise speed and angle coordination are required.

Its cooling relies on natural convection, so heat is shed directly through the housing without fans and cabinet airflow remains simpler. A protection rating of IP65 seals the stator and encoder against dust and washdown spray common on factory floors. Position data is transmitted over a Hiperface interface, and the embedded optical sensor provides 128 signal periods per revolution. This feedback method maintains accuracy in electrically noisy environments. The standard mechanical design, stator diameter code 101, and length code E balance torque density with footprint, while the power connector on the B-side supports cable routing away from the load.

The encoder is configured for single-turn measurement, reporting absolute rotor angle within one revolution while multi-turn tracking is handled by the controller. Continuous duty is permitted in ambient temperatures of 0–40 °C, which suits typical cabinet and machine conditions. A plain shaft provides direct coupling to clutches or pulleys, and the motor is supplied without a holding brake, so vertical axes require an external clamp when power is removed. Thermal class 155 insulation allows elevated winding temperatures during short overloads, and winding code 0450 indicates the coil resistance characteristics used by the drive for current-loop tuning.
