Product Description:

The MSK061B-0300-NN-M1-UG1-NNNN synchronous servomotor is produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S servomotor, it converts controlled electrical power into precise mechanical motion for industrial automation axes that rely on closed-loop feedback and rapid positioning. Closed-loop operation allows the paired drive to correct speed and position deviations during acceleration, deceleration, and load changes. It is used with IndraDrive controllers in packaging, printing, and material-handling lines.

Heat is removed through natural convection, so the housing dissipates losses without forced airflow and requires unobstructed ambient circulation. For position sensing, the unit uses an optical encoder with a Hiperface interface; that protocol carries power and bidirectional data through a rotatable 240° connector, which helps with cable routing in tight cabinets. The encoder provides 128 signal periods, supporting smooth velocity loops and accurate position feedback. An electrically released holding brake provides 10 Nm of static torque to secure vertical loads when power is removed. The motor has an IP65 enclosure rating, which protects against dust and low-pressure water jets during washdown cleaning.

Mechanical dimensions follow size 061 with motor length B, and the winding code 0300 matches the electrical characteristics expected by the drive. A multiturn absolute measuring system inside the optical encoder retains position across power cycles, so a homing sequence is not required after the brake is released. The output end uses a plain shaft, which supports backlash-free couplings in precision gearboxes. Continuous duty is intended for ambient temperatures from 0 to 40 °C, and the insulation system is rated 155 to keep thermal stress within Class F limits during convection cooling. The compact frame is suitable for installations where machine space is limited and accurate coupling alignment is important.
