Product Description:

The MDD065C-N-060-N2M-095PR1 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where it converts electrical command signals into precise rotary motion for positioning or velocity-controlled axes in automated machinery. By combining magnetic excitation from permanent magnets with electronic commutation, the motor delivers high dynamic response that suits pick-and-place stations, packaging lines, and other cyclic industrial processes. This arrangement lets the matching drive regulate speed and position with fast response during repeated start-stop motion.

The motor has a centering diameter of 95 mm, which aligns the stator housing concentrically with the machine frame and helps limit radial runout. At standstill, the electromagnetic system can exert 2.1 Nm of continuous torque, allowing the axis to hold loads or start smoothly without overheating. Under rated excitation, the rotor can reach a nominal speed of 6000 rpm, enabling fast indexing or high surface speeds in spindle applications. A spring-applied brake is fitted, and it secures the shaft with 3.0 Nm of static holding torque whenever power is removed. Power and feedback conductors exit on the right side of the flange, which can simplify cable routing when the cabinet is positioned to the left of the machine bed.

Torque is transmitted through a shaft with a keyway, so standard keyed couplings can be installed without additional machining. Closed-loop regulation uses Digital servo feedback (DSF) from an integrated multiturn absolute encoder, giving the drive immediate knowledge of position over multiple revolutions. That feedback arrangement lets the axis recover position data after a power cycle without a homing move. The unit uses series size 065, while the C length code adds extra active stack height for improved thermal capacity. Standard dynamic balancing minimizes vibration, and the shaft seal helps keep coolant spray or dust away from the front bearing area.
