Product Introduction
Bosch Rexroth MSK071E-0450-NN-M1-UP1-NNNN is a permanent magnet synchronous servo motor in the IndraDyn S series. It provides high torque in machine tools, robotics, packaging lines, and printing machinery.
It pairs with IndraDrive controllers supporting SERCOS, EtherCAT, or PROFIBUS. The multiturn absolute encoder maintains position across power cycles—no homing needed. Integrated 23 Nm holding brake secures vertical axes during shutdown. Keyway shaft suits direct coupling; natural convection suits enclosed cabinets without extra fans.
