Product Description:

The MSK101D-0300-NN-S1-BP3-NNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat in the MSK IndraDyn S Synchronous Motors series. The unit converts commanded current from a drive into controlled torque and angular position, making it suitable for positioning axes, gantry stages, and packaging machinery in automated lines. Its platform compatibility lets it operate with matching drive controllers for closed-loop motion control without extra interface hardware. That arrangement supports precise motion sequences where repeatable starts, stops, and position corrections are required throughout a machine cycle.

The motor uses the 101 frame, and its elongated D length increases active stack depth for higher continuous torque without changing the mounting footprint. Winding code 0300 sets the electrical characteristics so the drive can supply rated current without magnetic saturation. Cooling is provided by natural convection, which eliminates external blowers and reduces airflow demands around the machine. Power enters on side B, allowing cable routing parallel to the machine frame, and the shaft has a keyway so couplings can transfer torque through a positive mechanical fit. This combination is useful where the motor must fit within a fixed machine envelope while still supporting sustained duty.

An electrically released holding brake provides 120 Nm of torque, allowing the axis to remain locked when power is removed. Position feedback is supplied by a Hiperface optical encoder in single-turn operation, returning 128 signal periods per mechanical revolution so the controller can interpolate precise position data. This feedback arrangement supports accurate commutation at startup and stable position tracking during low-speed operation. The integrated brake also helps the motor hold vertical or suspended loads when the drive is not actively producing torque, which can improve control during pauses and restart sequences.
