Product Description:

The MSK101C-0202-NN-S3-AG0-NNNN is a synchronous servo motor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It is installed on articulated arms, gantry axes, and indexing tables where precise speed and position control are required. In these roles, the motor converts regulated three-phase power from an IndraDrive amplifier into repeatable rotary motion while its integrated encoder returns rotor data to the drive for closed-loop correction during acceleration and dwell. A frame size of 101 mm with length code C keeps the package compact enough for medium-duty stations without requiring wider machine frames or oversized mounting hardware.

Heat produced during operation is removed by natural convection, so the housing sheds heat without a fan and still needs vertical clearance for airflow. The motor’s position sensor communicates through a Hiperface link that carries incremental and absolute data on a single cable, which helps simplify feedback wiring. Within the feedback assembly, a capacitive measuring principle detects rotor movement with low sensitivity to magnetic fields near power conductors. Native sensor granularity is 16 signal periods per revolution, and the drive interpolates these edges for finer control. Because the encoder is a single-turn model, absolute position is available within one mechanical revolution, while any turn-count tracking beyond that range must be handled elsewhere in the control system.

A plain shaft is supplied for backlash-free clamp couplings or shrink discs, and the power connector is located on the motor’s A-side to keep the cable exit consistent with common machine layouts. The electromagnetic system uses winding code 0202, which sets electrical characteristics that match the current limits used in IndraDrive parameter sets and supports stable torque production. The motor is delivered without a holding brake, so parked loads must be secured by external means or by controlled drive torque when line power is removed. This layout suits applications that rely on accurate rotary motion without the added length or inertia of an integrated brake assembly.
