Product Description:

The MSK101E-0300-NN-S1-AP2-NNNN is an AC synchronous servomotor in the MSK IndraDyn S Synchronous Motors series from Bosch Rexroth Indramat. The unit converts inverter current into controlled rotary motion, supplying tightly regulated torque for automated handling cells, printing lines, and other precision axes. Its size 101 frame with length code E gives it a large mechanical envelope for heavier drive trains. When paired with a compatible drive, it supports accurate speed regulation and repeatable positioning under changing load conditions.

Heat is removed by natural convection, so the installation should allow free airflow around the housing. An integrated electrically released holding brake provides 70 Nm of static torque to help prevent load drift when power is removed. This brake is useful when the axis must remain stationary during a power-off condition. The housing is rated IP65, which helps keep dust and water jets away from internal components. The motor uses a keyed shaft for positive torque transmission to pulleys or gearboxes, and power and feedback connections are routed on the A-side. Feedback is transmitted over the Hiperface protocol through an optical sensor.

The encoder delivers 128 signal periods per revolution in a single-turn format, giving the drive accurate position data within one shaft rotation. This arrangement is suitable for axes that do not require multi-turn position storage inside the motor feedback system. Safe operation is permitted at ambient temperatures from 0–40 °C. The insulation system is class 155, allowing the windings to tolerate the heat produced during cyclic servo duty. Winding code 0300 matches the electrical characteristics used by compatible MSK drive modules, and the standard housing avoids the need for liquid cooling hardware or special shrouds in many open-machine layouts.
