Product Description:

The Bosch Rexroth Indramat MSK061C-0300-NN-M2-UP1-RNNN is a synchronous servomotor in the MSK IndraDyn S Synchronous Motors series that supplies precise torque and velocity for industrial automation axes. This motor combines a compact 061 frame size with a C-length stator section and the 0300 winding code so that it matches medium-power drives used in packaging, printing, and material-handling equipment. Its synchronous design supports accurate acceleration, stable speed regulation, and repeatable positioning when it is paired with a compatible servo controller. The motor is suitable for feed systems, indexing stations, and transfer axes where compact installation space and consistent motion response are important.

The unit is cooled by natural convection, eliminating the need for forced air or liquid circuits in cabinets with adequate airflow. Its housing meets IP65, so internal components remain protected from dust and low-pressure water jets. Continuous service is permitted within an ambient range of 0–40 °C, and the windings use thermal class 155 to withstand elevated internal temperatures without insulation breakdown. A keyed solid shaft transfers torque to couplings or driven elements, and the rotor and stator use an increased concentricity design that helps reduce radial runout during rotation. The electrically released holding brake provides 10 Nm of static torque when power is removed, which supports vertical axes and position-holding duties.

Position feedback is handled by an optical encoder that communicates through the EnDat2.1 digital interface. The encoder delivers 2048 signal periods per revolution, giving the drive fine position resolution for closed-loop control. Its connector can be rotated through 240°, which helps route cables in tight spaces and reduces strain at the motor entry point. The multi-turn absolute feedback format lets the control system retain shaft position information over several revolutions without requiring a reference move after power-up. The optical measuring system also avoids the brush wear associated with contact-based feedback devices.
