Product Introduction
The Bosch Rexroth MSK070D-0300-NN-S1-UG0-NNNN is a permanent magnet synchronous servo motor in the IndraDyn S series. It provides reliable torque delivery and higher rotational speeds in automation applications such as CNC machines, material handling, robotics, and packaging equipment when driven by IndraDrive controllers.
It features a single-turn hiperface encoder for accurate positioning within one revolution, natural convection cooling, plain shaft with sealing ring, and no holding brake. This variant supports 400–480 V three-phase supplies, offers IP65 protection, and achieves a good balance of torque density with elevated max speed for faster cycle times in non-brake-required axes.
