Product Introduction
The Bosch Rexroth MSK075D-0450-NN-S2-UG0-RNNN is a permanent magnet synchronous servo motor in the IndraDyn S series. It delivers consistent torque at higher speeds in automation setups such as CNC machines, robotics, material handling, and packaging when driven by IndraDrive controllers.
It includes a single-turn EnDat 2.1 encoder for high-resolution positioning within one revolution, natural convection cooling, plain shaft with sealing ring, and no holding brake. This RNNN reduced-runout design supports 400–480 V supplies, provides IP65 protection, and suits dynamic cycles in non-brake axes with improved mechanical accuracy.
