Product Description:

The MDD065A-N-040-N2L-095PA1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Designed for use with digital drive controllers, the unit converts electrical power into controlled shaft rotation for positioning, feed, or spindle tasks in automated machinery. By combining permanent-magnet excitation with internal feedback, it delivers repeatable velocity and torque profiles required for closed-loop motion axes. Its motor design also supports responsive acceleration and stable low-speed control in machine tools, packaging systems, and transfer equipment.

Mechanical interfaces start with a centering diameter of 95 mm, which aligns the flange to gearboxes or machine frames. Power and feedback connectors are located on Side A, so cables exit parallel to the drive shaft. The electrical interface uses a sealed connector type for protected cable attachment. Under rated conditions, the rotor can reach 4000 rpm, and the drive must supply the corresponding electrical frequency. Continuous torque at standstill is 0.8 Nm, indicating how much load can be resisted without motion while temperature remains within limits. When power is removed, a blocking brake holds up to 3.0 Nm, allowing vertical loads to stay in place. Position data returns to the controller through digital servo feedback, enabling high-resolution commutation and rapid servo loops.

Motor size 065 corresponds to the stator diameter used for this torque class, while the compact length code A keeps overall depth low in space-limited installations. A keyway shaft end transmits torque directly into couplings, and the output side is delivered with a shaft seal to limit lubricant ingress from adjoining machinery. Standard dynamic balancing reduces vibration at speed, and the housing follows the standard series pattern used for common mounting arrangements. The sealed output end also helps protect the bearing area when the motor is installed beside lubricated transmission components.
