Product Description:

The MDD090C-N-030-N2M-130GA1 is produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. It serves as a rotating actuator for digital drive controllers, supplying commanded torque and speed to automated machine tools, handling stations, and packaging lines. A standard housing, connector-based cabling, and an integrated encoder support straightforward installation and closed-loop motion control. This arrangement allows the drive to monitor rotor position continuously during positioning and speed-regulated operation.

Under continuous stall conditions, the motor can deliver 10.4 Nm of torque, allowing it to hold static loads without external gearing. During operation, it reaches a synchronous speed of 3000 rpm, which suits applications that require rapid indexing or short cycle times. The centering pilot measures 130 mm, providing a reference surface that aligns the stator concentrically with the machine frame to minimize runout. Power, brake, and feedback connectors are oriented on Side A, so the cable exit follows the same direction as adjacent axis wiring. A blocking brake supplies 6.5 Nm of holding torque, and it engages automatically when the drive is disabled to help prevent unintended motion on vertical or suspended loads.

An integrated multi-turn absolute encoder records position across multiple revolutions, eliminating the need for homing after power-up and supporting the motor’s digital servo feedback interface. The output shaft is a plain shaft without a second shaft end, reducing overall length and easing coupling alignment. A dedicated shaft seal sits behind the front bearing to limit lubricant loss and block dust or coolant ingress at the coupling face. With a frame designation of 090 and standard dynamic balancing, the rotor runs smoothly during acceleration and deceleration. These features make the motor suitable for repeatable motion in automated equipment that depends on accurate feedback and secure shaft sealing.
