Product Description:
The MSK100B-0300-NN-M1-BG2-NNNN is an IndraDyn S synchronous servo motor produced by Bosch Rexroth Indramat and assigned to the MSK IndraDyn S Synchronous Motors series. This brushless AC unit is used in automated machinery where repeatable torque delivery, high-resolution feedback, and rapid acceleration are important. It links directly to IndraDrive controllers to convert three-phase energy into controlled rotary motion for indexing tables, pick-and-place actuators, and coordinated multi-axis systems. Its operating profile suits equipment that must start, stop, and reposition frequently while maintaining consistent motion accuracy.
In operation, the motor releases heat through natural convection, so no auxiliary fan or liquid circuit is required, and normal ambient airflow removes generated heat. An electrically released holding brake supplies 70 Nm of static torque, allowing vertical loads to remain stationary when power is removed. The feedback channel uses the Hiperface serial interface, and its sensor scans 128 signal periods per mechanical turn for position tracking. Because the sensing method is optical, it resists magnetic interference, and its multiturn absolute design retains shaft position information across power cycles.
The output spindle is a plain shaft, so couplings or pulleys can mount without a keyway. Power and brake conductors exit on the B-side, which can simplify cable routing where space beside the load is restricted. Winding code 0300 identifies the stator winding arrangement used for this motor and matches the electrical values expected by compatible drives. The motor uses size 100 geometry with frame length B, which helps maintain a predictable installation envelope in compact machine layouts. This arrangement is useful where nearby guards, tooling, or transfer hardware limit clearance around the motor body.
