Product Description:

The MDD090C-N-020-N2M-130GA2 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed to work with digital drive controllers, it converts regulated armature current into precise rotary motion for positioning and speed-controlled axes in automated machinery. Its integrated feedback and brake support closed-loop operation where the axis must respond quickly to command changes and hold position after motion stops. Because it is built for servo use, the drive can compare commanded and actual motion continuously and correct for load changes during operation. This makes the motor suitable for material handling systems, packaging equipment, and other factory automation tasks that require repeatable motion.

The motor provides a continuous standstill torque of 10.4 Nm, allowing it to hold a steady load at zero speed without overheating when the shaft remains locked. During operation it reaches a nominal speed of 2000 rpm, which fits common production cycles and coordinated servo movement. The integrated blocking brake supplies 11.0 Nm of holding torque to help prevent drifting when power is removed. That brake is useful on vertical or suspended axes where unintended movement must be minimized between operating cycles. Mounting accuracy is supported by a centering diameter of 130 mm, and all power and signal conductors exit on Side A through a keyed circular connector. The rotor is balanced to the standard grade, the housing uses the standard layout for this frame, and the motor has length code C in the 090 size class.

Position feedback is provided by an integrated multi-turn absolute encoder, while the embedded digital servo feedback channel delivers the position data required by the controller. Absolute position remains available after power cycling, which helps the axis resume operation without a homing move in many machine layouts. The output end uses a shaft seal to help keep contaminants away from internal components and reduce lubricant escape near the bearing area. Torque is transferred through a plain shaft, which is intended for couplings that clamp directly to the shaft surface. The opposite end has no secondary shaft extension, which simplifies the motor geometry. The motor uses a connector interface for quick cabling, and its standard housing layout fits the mechanical arrangement typical of this frame.
