The Bosch Rexroth's MDD digital AC servo motor, R911270835 (MDD093C-N-040-N2L-110PA2), is a permanent magnet motor optimized for rapid-response automation systems when combined with Indramat drive controllers. This versatile motor offers high contouring accuracy and is typically deployed in textile and tool machines, robotics, and handling equipment. The R911270835 (MDD093C-N-040-N2L-110PA2) model sports a 110mm centering diameter and an optical digital servo feedback encoder with an accuracy of ±0.5 angular minutes, capable of recording rotor position relative to the drive controller, and can relay this information directly to the NC master control. Created for highly dynamic applications, the motor has a nominal speed, rotor moment of inertia, winding inductance, theoretical maximum torque, and peak current of 4,000 rpm, 42 x 10⁻⁴ kgm², 1.6mH, 60.6Nm, and 204.0A, respectively. Its shaft comes with a keyway for torque transmission, a 22Nm integrated blocking brake, and a black prime coat that is resistant to dilute acids and weather damage. This product, classified in Balance Class R per DIN VDE 0530 standards, is suitable for demanding main spindle applications.
