Product Introduction
The Bosch Rexroth MSK071C-0450-NN-M1-UP1-NNNN is a permanent magnet synchronous servo motor in the IndraDyn S series. It delivers dynamic performance and precise motion in applications like CNC machinery, robotics, material handling, and packaging lines when paired with IndraDrive drives.
It includes a multi-turn hiperface encoder for absolute positioning across revolutions, natural convection cooling, plain shaft with sealing ring, and a 23 Nm holding brake. This setup ensures IP65 protection, supports 400–480 V supplies, and provides elevated max speed for faster cycles in brake-required axes where load holding prevents unintended movement.
