MDD065C-N-040-N2M-095GR0
The MDD065C-N-040-N2M-095GR0 is a synchronous servo motor built by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for use with digital drive controllers, providing closed-loop motion in automated handling, packaging, and assembly stations. In these systems, the motor serves as the rotary actuator and converts commanded current into controlled speed and torque. The closed-loop arrangement allows the connected drive to react to motion deviations during acceleration, deceleration, and position holding.
A centering flange diameter of 95 mm simplifies coaxial mounting, while the 065 frame size and C length code place the motor in the mid-power range of the family. Continuous stall torque is rated at 2.1 N·m, providing stable holding force for static loads, and the rated mechanical speed reaches 4000 rpm for rapid indexing cycles. Power and feedback conductors exit on the right side through a keyed connector, which helps reduce installation depth inside crowded cabinets and can simplify cable routing. The rotor is balanced to the standard grade, the housing uses the standard enclosure design, and the absence of a secondary shaft end keeps inertia low while leaving more rear clearance for nearby components.
An integrated multi-turn absolute encoder reports rotor position across multiple revolutions, and the drive uses digital servo feedback for high-resolution velocity control. This feedback method supports stable speed regulation during repeated indexing and reversing cycles. The motor is supplied without a blocking brake, so an external holding method is needed when power-off load retention is required. A fitted shaft seal helps separate lubricant and contaminants at the rotating interface, and the output end uses a plain shaft for coupling or pulley attachment without keyways.
