Product Description:

The MDD065B-N-040-N2M-095GL0 is a synchronous servo motor produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Intended for use with digital drive controllers, the unit converts electrical power into controlled rotary motion in industrial automation platforms. It supplies precise speed and torque that match the command profile issued by the drive. In a closed-loop system, the motor responds to changing load conditions while maintaining commanded motion.

The motor can deliver a continuous standstill torque of 1.5 Nm, allowing light-duty axes to hold position without overheating. A nominal speed of 4000 rpm is the upper sustained shaft velocity that can be maintained when the drive provides rated current. Mechanical centering is aided by a 95 mm centering diameter, ensuring concentric alignment with gearboxes or mounting flanges. Feedback to the controller is sent through digital servo feedback; this electronic interface supplies position data for closed-loop regulation. The rotor has a plain shaft, so power is transmitted through friction-fit couplings rather than keyed interfaces. All electrical terminations exit on the left side of the housing, which can simplify cable routing in tight machine layouts.

An electrical connector provides a detachable interface for the power and signal leads. The motor is supplied without a blocking brake, so position retention during power loss must be handled by the drive or an external clamp. Position resolution relies on the integrated multi-turn absolute encoder, which counts multiple revolutions without a battery. Dynamic performance is supported by standard balancing, keeping vibration within IEC limits across the rated speed range. Additional protection comes from a shaft seal that helps block lubricant or coolant ingress while the housing remains a standard ventilated design.
