Product Description:

The MSK101D-0300-NN-S1-BG2-NNNN is an IndraDyn S synchronous servo motor built by Bosch Rexroth Indramat for precision positioning tasks in automated machinery. It belongs to the MSK IndraDyn S Synchronous Motors series, uses a standard design, and has motor size 101 with D length. Mechanical power is delivered through a plain shaft, while the power connector is located on the B-side of the housing. An electrically released holding brake is integrated to keep the axis secure when drive power is removed. This layout supports feed axes, indexing units, and other servo applications that require repeatable motion and controlled stopping.

Thermal management is based on natural convection, but external airflow is required when the motor runs continuously at rated load. This helps limit internal heating in tightly packed machine spaces and supports stable operation over longer duty periods. For feedback, an optical encoder with the Hiperface protocol generates 128 signal periods per revolution, supplying position data to the drive controller. Interpolation in the drive also provides velocity feedback without additional sensors. The holding brake delivers 70 Nm of torque, and the IP65 enclosure helps keep dust and water jets away from internal motor parts.

The encoder operates in single-turn mode, so absolute position is available within one mechanical revolution without multi-turn counting. This arrangement supports applications that need known shaft position after startup within a single turn of travel. Winding code 0300 identifies the electrical winding used with compatible IndraDrive amplifiers. Insulation class 155 allows the winding system to operate at elevated temperature without loss of dielectric integrity. Continuous operation is permitted in ambient temperatures from 0 to 40 °C, and operation outside that range requires derating or added cooling.
