Product Description:

The MDD065D-N-040-N5M-095GA0 is a synchronous AC servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it converts the pulse-width modulated output of an Indramat drive into controlled mechanical rotation for positioning axes and cyclic machinery. The motor fits the 065 frame envelope, making it suitable for medium-duty applications that require a compact footprint and stable speed regulation. Its synchronous design supports precise coordination between the drive’s electrical commands and the resulting shaft movement in industrial automation systems.

At the mechanical interface, the stator housing has a centering pilot of 95 mm, enabling repeatable alignment on gearbox flanges or mounting plates. During continuous operation, the motor develops 2.7 Nm of torque at standstill while maintaining its permissible operating temperature. Dynamic operation reaches a nominal shaft speed of 4000 rpm, allowing the motor to follow fast indexing cycles without losing positional control. The internal lamination stack has a length code of D, providing a longer magnetic core than shorter models with the same frame size and increasing power density. Position and speed data are returned through digital servo feedback, while an integrated multi-turn absolute encoder tracks rotor position across multiple revolutions for accurate homing. The motor is supplied without a blocking brake, so applications with vertical loads or holding requirements must use external braking or clamping.

The mechanical output uses a plain shaft, so torque is transmitted through an interference-fit coupling rather than a keyway. A radial connector on side A routes the power, feedback, and protective ground conductors away from rotating components. This connector position also helps organize cable routing when the motor is installed in machinery with limited clearance. Contaminant ingress along the shaft is restricted by operation with a shaft seal, which protects the bearing area during extended service. The motor also uses a standard housing and standard dynamic balancing grade to control vibration during high-speed operation. These features suit installations in servo-controlled gantries, packaging equipment, and light machining centers where precise motion and compact motor dimensions are required.
