Product Description:

The MDD025B-N-100-N2K-040MR0 is a compact synchronous servo motor from Bosch Rexroth Indramat in the MDD Synchronous Motors series. It is designed for digital drive controllers and converts inverter current into precise rotary motion for pick-and-place stations, electronic assembly lines, and light spindle duties. Its compact 025 frame supports high-speed operation while keeping the installation footprint small in automated equipment. This layout suits axes that need quick response, repeatable positioning, and stable motion where available mounting space is limited. Because it is intended for light industrial motion, it can be used where frequent starts, stops, and direction changes are part of the normal duty cycle.

At standstill, the motor can deliver a continuous torque of 0.60 Nm, which allows an axis to hold light loads without overheating the stator windings. It reaches a nominal mechanical speed of 10000 rpm when paired with a suitable drive, making it suitable for short cycle times and fast indexing tasks. A 40 mm centering diameter supports accurate flange alignment, and electrical connections are made through a plug-in connector on the right side of the end cap for straightforward cable routing. The right-side connection point is also useful in narrow machine sections where cable bends need to be controlled close to the motor. The motor is supplied without a blocking brake, so any holding force at standstill must come from external mechanical components.

The rotor uses standard balancing, which helps keep vibration low even near maximum speed. Position data is provided by an integrated absolute encoder, and the drive receives the motor feedback through a resolver feedback connection. Torque is transmitted through a shaft with a keyway on side A, and the motor is built without a shaft seal for use inside protective enclosures. This arrangement supports direct coupling to compatible transmission components while keeping the feedback package integrated within the motor body. The standard housing and length code B body keep the mechanical layout consistent with other motors in the same product line, which helps when matching the motor to compact machine assemblies.
