Product Introduction
The Bosch Rexroth MSK071D-0300-NN-M1-UP0-NNNN is a permanent magnet synchronous servo motor in the IndraDyn S series. It supplies substantial torque at controlled speeds in automation like CNC machines, robotics, material handling, and packaging when connected to IndraDrive drives.
It features a multi-turn hiperface encoder for absolute positioning over multiple revolutions, natural convection cooling, plain shaft with sealing ring, and no holding brake. This configuration maintains IP65 protection, supports 400–480 V supplies, and offers increased torque density in length D for demanding load applications without brake needs.
