Product Description:

The MSK071C-0200-NN-S1-UG2-NNNN is a synchronous servomotor built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It drives position-controlled axes in automated machinery where accurate torque and speed regulation are required for repeatable motion. Inside a sealed housing, the motor integrates an optical single-turn encoder, an electrically released holding brake, and a feedback connector that rotates 240° so it can be oriented to match cabinet layouts. This arrangement supports compact installation in packaging, handling, and general automation equipment.

This unit uses motor size 071 and winding code 0200, a combination that sets its electromagnetic constants and current demand. Heat is removed through natural convection; no forced air or liquid circuit is supplied, so the installation must allow free airflow in the specified mounting position. The IP65 protection rating prevents dust ingress and water jets from reaching internal components, which is important when the motor is mounted outside sealed machine enclosures. Reliable operation is limited to an ambient range of 0–40 °C, and outside this range the motor requires derating or additional cooling. The motor uses insulation class 155, and the stator has a standard C length that gives a balanced inertia-to-torque profile for medium-duty cyclic loads.

The motor has a plain shaft, simplifying coupling with shrink discs or clamp hubs and avoiding keyway stress risers. A holding brake rated at 30 Nm clamps the rotor when power is removed, and its release coil is fed directly from the drive controller. Position data is returned through the Hiperface interface, and the optical encoder generates 128 signal periods per mechanical revolution for fine commutation data in compatible servo amplifiers. The connector can be rotated during installation to reduce cable strain, and the FN cooling requirement flag indicates that any additional thermal load must be evaluated before the axis operates at continuous full torque.
