Product Description:

The MDD065D-N-040-N2M-095PB1 is a synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts drive current into precise rotary motion for automated machinery, packaging lines, and material-handling axes. Its integrated multi-turn absolute encoder and digital servo feedback allow the controller to read exact shaft position at power-up, which reduces homing time, supports repeatable cycle starts, and improves position availability after interruptions.

The mechanical envelope is centered by a 95 mm pilot diameter, which aligns the housing to mating machine plates without extra bushings. Power and feedback cabling exit on Side B through a single connector, keeping the opposite face clear for close-coupled installations. At standstill, the electromagnetic system can deliver 2.7 Nm of continuous torque, enabling the drive to hold loads or apply low-speed force without overheating. When operated with a matched inverter, the rotor reaches a nominal speed of 4000 rpm, which suits light mechanical stages and fast indexing duties. The D length uses an extended stator stack that supports higher magnetic loading than shorter versions.

During power loss, the integrated blocking brake supplies 3.0 Nm of static torque so vertical or suspended axes remain in place until commanded release. A hardened keyway on the shaft transmits torque to pulleys or couplings without slip, and a dedicated shaft seal helps keep contaminants and migrated lubricant away from internal parts. The compact 065 frame size uses standard balancing to limit residual vibration, which helps protect adjacent bearings, couplings, and sensing elements during repeated motion. This layout fits servo axes that need secure shaft engagement and retained position after shutdown.
