MDD065A-N-040-N2M-095PR0
The MDD065A-N-040-N2M-095PR0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. It is built for digital drive controllers, so it converts drive current into precisely regulated shaft rotation for automated stations such as pick-and-place arms or small indexing tables. Its synchronous design supports accurate positioning and repeatable speed control in compact automation equipment. The 065 frame size, compact A-length body, and standard housing help it fit in tight installations, while standard balancing helps limit vibration during rapid acceleration.
This model can hold a continuous standstill torque of 0.8 Nm, which is the continuous torque available at zero speed while the motor remains energized. During operation, it reaches a nominal speed of 4000 rpm, giving the application a wide operating range for medium-duty positioning tasks. A centering diameter of 95 mm aligns the flange accurately on mounting surfaces and helps keep shaft runout low. This flange fit supports consistent alignment when the motor is mounted to compact machine modules or geared assemblies. Power and feedback cables exit on the right side, and the connector interface keeps wiring compact. The motor also has a standard shaft end with no side-B extension and a shaft seal that helps keep grease in place and contaminants away from the bearing set.
Position reporting is handled by an integrated multiturn absolute encoder, allowing the controller to retain rotor position information after power loss. The motor transmits this data through digital servo feedback, which supports high-resolution commutation and stable velocity control. This feedback arrangement supports closed-loop motion control without separate external position sensors on the axis. A keyway on the shaft provides positive torque transmission to pulleys or couplings under reversing loads. Because the unit is supplied without a blocking brake, static holding must be provided by drive torque or an external clamping device.
