MDD065D-N-040-N2M-095PR0
The MDD065D-N-040-N2M-095PR0 is a synchronous servo motor built by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it converts regulated current from the drive into rotational motion for positioning or velocity loops in automated machinery. This operating principle supports repeatable motion in feeders, transfer units, and similar servo axes where the controller continuously corrects speed and position. The unit uses the 065 frame class and a standard single-ended shaft, permitting direct coupling to gearboxes or load elements in compact assemblies.
It delivers a continuous standstill torque of 2.7 Nm, allowing stable load holding without overheating when the axis is energized but motionless. During normal operation, the rotor can reach a nominal speed of 4000 rpm. That speed suits applications that require fast cycle times without moving to a larger motor platform. Accurate mechanical alignment is assisted by a centering diameter of 95 mm, which locates the housing against the mounting pilot bore. Electrical and feedback leads exit on the right side, so the installation must reserve clearance on that flank. Position verification is carried over a digital servo feedback interface, enabling high-resolution closed-loop control through Rexroth drive amplifiers.
An integrated multiturn absolute encoder records angular position across multiple revolutions, so the motor can report position after a power cycle without a homing move. Because the motor is supplied without a blocking brake, any hold-on-power-off requirement must be handled by external clamping or drive torque. The output shaft uses a keyway profile and includes a shaft seal, providing positive torque transmission while helping protect the interior against contamination. A standard dynamic balancing grade, the housing design, and the D-length stator section help limit vibration and support steady thermal behavior. Connector-based power and signal terminations simplify installation and keep cable attachment separate from the mounting surfaces.
