R911255791
The R911255791 (MDD065D-N-040-N2M-095GB0) is a product of Bosch Rexroth Indramat, part of the MDD Series of synchronous servo motors renowned for high accuracy and brisk feed rates. Ideal for use in machine tools, robotics, and textile applications, the R911255791 (MDD065D-N-040-N2M-095GB0) offers exceptional power density making it perfect for applications requiring high dynamics such as pressing, punching, and tool-changing devices. This motor boasts a nominal speed of 4,000 rpm and maximum torque of 7.8Nm, and is designed to be installed in any position on a machine with the ability for direct attachment of pinions and belt pulleys to the shaft. Its housing is both dust-proof and touch-proof, resisting even water jet sprays, meriting an IP 65 per EN 60529 rating, making it reliable for use in harsh industrial conditions.
The low inertia characteristic of the R911255791 (MDD065D-N-040-N2M-095GB0) is largely due to its rotor, carefully crafted from rare earth and iron oxide materials. The permanent magnet in the rotor has a moment of inertia of 3.8 x 10-4 kgm2. It features a digital servo feedback mechanism with an integrated multiturn absolute encoder, which ensures precise evaluation of the motor’s speed and position over time, with a system accuracy of ±0.5 angular minutes. The encoder is equipped with a data memory feature to enhance the motor’s startup speed.
