Product Description:

The MSK061C-0300-NN-S3-UG1-NNNN synchronous servomotor is manufactured by Bosch Rexroth Indramat and belongs to the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S servomotor, it converts electrical energy into controlled torque and speed for positioning and velocity loops in automated machine tools, packaging lines, and handling modules. Its compact 061 frame and length C stator stack make it suitable for moderate-power axes where fast dynamic response and closed-loop accuracy are required. This motor format is well suited to applications that need repeatable motion in a limited installation space, especially where quick starts, stops, and direction changes are common.

Heat is removed through natural convection, so the motor operates without a fan when surrounding airflow is adequate. The sealed housing carries IP65 protection, helping keep dust and water jets away from the windings and encoder components. Reliable operation is limited to an ambient temperature of 0 to 40 °C, and operation beyond that range requires derating or additional cooling. The encoder connector rotates 240° to help align the cable with the machine layout and reduce routing strain. Position data comes from a capacitive sensing head, which is less affected by external magnetic fields. A standard mechanical layout, a plain shaft, the 0300 winding, and insulation class 155 support the motor’s torque behavior and thermal capability for this frame size.

The encoder communicates with the drive controller over the Hiperface digital interface, supplying absolute position data at startup. Within one motor revolution, the sensor provides 16 signal periods, and drive-side interpolation supports smooth speed regulation during contouring and positioning tasks. Because the unit uses a single-turn encoder, it reports position within one revolution, while any multi-revolution tracking must be handled by the control system. An electrically released holding brake is integrated for vertical or static loads, and it provides 10 Nm of holding torque when power is removed. The motor also uses a plain shaft for force-fit couplings, allowing direct connection to gear stages or timing pulleys in compact axis assemblies.
