MDD025A-N-100-N2G-040FD1
The MDD025A-N-100-N2G-040FD1 is a small-frame synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it provides closed-loop rotary motion for lightweight pick-and-place axes, labeling heads, or miniature spindles where high speed and quick acceleration are needed. The unit is supplied in a standard housing with standard balancing and includes a blocking brake to keep the load stationary when power is removed. Its compact format helps it fit applications where actuator spacing is tight and low inertia is important for responsive motion.
A nominal speed of 10000 rpm allows the rotor to support rapid cycle times, while the continuous torque at standstill is 0.33 Nm, which is the sustained twisting force available for static positioning tasks. When the blocking brake is engaged, it can hold up to 1.0 Nm, helping prevent creep on vertical or servo-press axes. A 40 mm centering diameter supports accurate alignment during mounting, and all power and feedback leads exit on Side B so cable routes can remain fixed. Standard balancing helps limit residual vibration during operation.
The motor is wired through a connecting cable with coupling unit, and this plug-through arrangement simplifies connection in modular machines. Rotor position is reported through built-in resolver feedback, enabling the drive to perform commutation and fine speed regulation without an external encoder. With the compact size code 025 and length code A, the frame occupies minimal space alongside neighboring actuators. A plain shaft is supplied for clamp or collar couplings, and the shaft end on side B is omitted to save length. Because the motor is delivered without a shaft seal, it should be installed inside an enclosure where oil or coolant ingress is not expected.
