Product Description:

The MSK100B-0300-NN-S1-BP1-NNNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. It is intended for closed-loop position and speed control in industrial automation lines where repeatable motion is critical. The motor integrates a multi-pole rotor, an optical encoder, and an electrically released holding brake, allowing an IndraDrive controller to command smooth acceleration, capture real-time feedback, and secure the load during power-off states. This arrangement supports precise axis behavior during both motion and standstill. It also reduces the need for separate external feedback or holding components at the machine axis.

The brake can withstand up to 32 Nm of static torque, letting vertical or suspended axes remain locked without external clamps. Heat is removed by natural convection, so the housing must have unobstructed airflow rather than forced cooling. Position data is returned over the Hiperface digital interface, which carries both incremental and absolute signals and simplifies cabling between the motor and drive. Inside the encoder, the scale provides 128 signal periods per revolution, giving the controller fine angular resolution for interpolation. The sensing method is optical, which avoids magnetic offsets and helps maintain accuracy as temperature changes.

The feedback device is a single-turn model, so absolute position is retained over one revolution and homing is required only at cycle start. Power leads exit on the B-side, enabling cable routing opposite the feedback connector. Mechanical coupling is through a shaft with keyway, which provides positive torque transmission to a keyed hub. The motor uses winding code 0300, which matches compatible IndraDrive amplifiers for current and voltage limits. The stator size and housing length provide additional active material for higher continuous torque while staying within standard frame dimensions.
