Product Description

This MDD Digital AC Servo Motor is introduced by Indramat, which is a wholly-owned subsidiary of the Bosch Rexroth family. Bosch Rexroth is a global provider of drive and control technologies on the industrial and commercial levels. The MDD071A-N-030-NZS-095GA1 model has a permissible ambient temperature range of 0? to +45 ?C for an altitude of 1000 meters above sea level. This 6.5kg MDD digital AC servo motor has a peak current value of 16.5 amperes. The torque constant and winding resistance of the model are 0.60 Nm/A and 4.54 Ohm, respectively at 20 ?C. The motor housing is coated with black prime-coat (RAL 9005) which provides resistance against corrosion and yellowing. Its winding inductance is 19.4mH and the moment of inertia of the rotor is 4.4 x 10-4 kgm2. The tremendous power density of the MDD071A digital AC servo motor enables its use in high-dynamic applications, including tool-changing devices and roller inputs for pressing, punching, and nibbling machines. It provides a high degree of operational reliability due to its lifetime lubricated bearings and brushless design. The MDD071A-N-030-NZS-095GA1 model has a plain shaft designated for shaft-hub connections that are not positive in nature. The nominal motor speed is 3000 min-1 and has a thermal time constant of 45 minutes. The permanent magnet-excited synchronous motor has a theoretical maximal torque of 6.9Nm. In addition to detecting rotor position, the digital servo feedback permits the evaluation of velocity and position. The MDD071A-N-030-NZS-095GA1 model facilitates precise contouring at high federates when employed for cutting at high speeds. The insulation classification of the MDD series is F, and its protection category is IP 65. This digital drive motor has a blocking brake of 3.0 Nm and can be attached to the machinery in any desired orientation.
