Product Description:

The MSK100D-0350-NN-S1-BP0-NNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. In automated production cells, this motor converts regulated drive current into precise torque and speed for axes that demand tight position control. Its electromagnetic construction works with an integrated optical feedback element so a connected drive can maintain accurate velocity loops during continuous duty.

Heat is removed through natural convection, so the housing relies on ambient airflow instead of forced fans, which affects mounting clearances and permissible continuous current. Position data travel over the Hiperface interface, which carries incremental and absolute information on the same conductors for use with compatible IndraDrive controllers. The built-in encoder generates 128 signal periods per mechanical turn; after interpolation, this supports fine commutation and low-speed ripple. Because the sensing principle is optical, magnetic fields from adjacent devices do not disturb the feedback. The encoder is single-turn, delivering an absolute angle within one revolution, which is sufficient for rotary axes that perform a mechanical homing routine at power-up. Winding code 0350 indicates the stator impedance and voltage constant, while the D-length stack increases torque compared with shorter variants.

The motor is supplied without a holding brake, so external clamps or sustained drive torque must secure the load during power-off. It uses frame size 100, giving a mounting footprint compatible with common MSK flange patterns and a rotor diameter suited to medium inertia requirements. Power conductors exit on the B-side, which simplifies cabling when the shaft faces outward from a cabinet. Torque reaches the application through a shaft with keyway, providing positive engagement with pulleys or couplings and helping prevent slippage under cyclic acceleration. The standard housing maintains IP65 sealing, and the front bearing area remains unobstructed for airflow.
