Product Description:

The MDD041A-N-100-N2K-050FA0 is a compact servo motor in the MDD Synchronous Motors series from Bosch Rexroth Indramat. It is intended for operation with digital drive controllers, where regulated current is converted into fast rotary motion for light-duty actuators, indexing spindles, and small transfer stations. Its compact housing helps it fit into tight machine spaces, and the built-in position sensing supports closed-loop control for accurate movement in automated equipment. This layout is suited to applications that need quick response without requiring a large motor frame.

The motor reaches a nominal speed of 10000 rpm, which supports high-speed cycles in tooling that must accelerate and decelerate quickly. A continuous standstill torque of 0.64 Nm allows the shaft to hold position under load without excessive thermal stress during low-speed or stopped operation. The centering diameter is 50 mm, giving the motor a precise mounting reference for alignment with surrounding machine parts. Power and feedback cables exit on the A-side, which keeps both connections on one face of the housing for straightforward cable routing. The output uses a plain shaft, so couplings or pulleys can be clamped directly to the journal without a keyed interface.

Position data is provided by an integrated absolute encoder, which supplies multi-turn feedback so the drive can retain shaft position information after power cycles. Dynamic behavior is supported by standard balancing, which helps limit radial vibration across the operating speed range. The physical package uses motor length code A, making it the shortest version in this family and useful where installation depth is limited. Electrical connection is made through a single plug-in connector, and the motor is supplied without a blocking brake or shaft seal to keep rotating mass and inertia low.
