Product Description:

The MDD025A-N-100-N2G-040MF0 synchronous servo motor is produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. It is a compact rotary unit intended for use with digital drive controllers where high spindle speeds are required in a small frame. By operating as the electromechanical interface between the controller and the machine axis, the motor converts drive currents into precise rotary motion for automated assembly equipment, pick-and-place heads, and similar high-cycle stations. Its compact format makes it suitable for installations where available mounting space is limited and fast response is important for repeated motion.

This model delivers a continuous standstill torque of 0.33 Nm, allowing light loads to be held without external gearing. Its maximum operating velocity reaches 10000 min⁻¹, so rapid positioning tasks can be completed in short cycle times. Motor power and feedback are routed on the right side through a connecting cable with a coupling unit, which helps cable routing in narrow machine spaces. Speed and position information is generated by resolver feedback, providing sine-cosine signals that remain stable across temperature changes and electrical noise. The unit is supplied without a blocking brake, so any holding function must be provided elsewhere when the axis is stationary.

A centering pilot of 40 mm aids concentric mounting to gearboxes or adapter plates. Frame code 025 and length code A indicate a compact housing that fits small tooling zones and lightweight axis layouts. Power is transmitted through a single-ended shaft machined with a keyway, and there is no side B shaft extension. The motor is built without a shaft seal, so it is better suited to clean, dry environments where fluid exposure is not expected. Standard balancing helps support smooth running, and the standard housing format keeps the mechanical arrangement straightforward for installations that use digital drive controllers.
