Product Description:

The MDD093B-N-040-N2M-130GA0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Intended for direct connection to the manufacturer's digital drive controllers, it converts regulated current into precisely commanded rotation for assembly, packaging, and material-handling axes. Its integrated encoder supports closed-loop operation, allowing the drive to monitor rotor position continuously and correct motion errors during acceleration, deceleration, and steady-speed travel. This type of motor is commonly used where repeatable positioning and stable speed control are required within compact machine layouts.

The motor's flange registers against a centering diameter of 130 mm, giving repeatable alignment during installation. Power and feedback conductors exit on Side A through a single industrial connector, which helps keep cable routing compact near the machine interface. That arrangement also keeps the connection area on one side of the housing, which is useful when the motor is mounted close to guarding or a gearbox. It can hold loads at a continuous standstill torque of 14.5 Nm without exceeding thermal limits. The unit is supplied without a blocking brake, so static holding must be provided by the drive or an external locking device. During motion, its nominal synchronous speed of 4000 rpm supports rapid index cycles while keeping rotor losses within the cooling capacity of the standard housing. Standard dynamic balancing helps reduce vibration as shaft speed increases.

Position data are returned through digital servo feedback from the multiturn absolute encoder, enabling precise loop closure in multi-axis systems and allowing position information to remain available after startup without a reference run. Torque is transmitted by a plain shaft, and the front bearing region is protected by a shaft seal that retains grease and helps keep dust away from internal components. The 093 frame with B length code gives the motor a mid-range installation envelope that fits many servo-driven mechanisms. The single-ended shaft layout leaves the rear area free for the feedback package and supports compact mounting where clearance behind the motor is limited. The sealed front end also helps protect the bearing area in factory environments where light airborne debris may be present.
