MDD065A-N-040-N2M-095PR1
The MDD065A-N-040-N2M-095PR1 is a synchronous motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Supplied for use with digital drive controllers, it is used to generate precisely regulated rotary motion in automated machinery. The unit’s blocking brake holds the load during power-off states, and its standard housing and balancing allow direct installation without supplementary vibration measures.
The flange has a centering diameter of 95 mm, which aligns the motor concentrically to the driven assembly. At standstill, it can develop 0.8 Nm of continuous torque, which indicates the thermal load when the shaft remains stationary under servo lock. Feedback accuracy is obtained with an integrated multiturn absolute encoder, and position data are transmitted through digital servo feedback (DSF) to the drive controller. Power and feedback conductors exit to the right because the connection direction is right-hand and the interface is a sealed connector. A keyway is machined into the standard shaft end so torque can be coupled with keyed hubs. The motor length code is A, indicating the shortest frame in the 65 mm size class, and the housing is delivered in the standard configuration without additional cooling fins.
When power is removed, the brake supplies 3.0 Nm of holding torque to prevent shaft rotation. During motion, the rotor reaches a rated speed of 4000 rpm, matching drive outputs that operate on 8 kHz current loops for tight velocity control. The frame code 065 establishes a compact outer diameter that suits multi-axis platforms where space is limited. There is a permanent shaft seal that blocks lubricant migration along the shaft journal, and the standard shaft end on side A is paired with no shaft extension on side B, reducing overall length while keeping enclosure integrity.
