Product Description:

The MDD090C-N-030-N2M-110GB0 synchronous servo motor is manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Intended for use with the firm’s digital drive controllers, it translates regulated three-phase current into controlled mechanical motion for indexing tables, gantry axes, and other automated stations. The motor’s medium-length C frame and 090 size fit compact footprints while still providing the torque density needed in continuous industrial duty on medium-load axes.

At a nominal rotor speed of 3000 rpm, the motor can keep shaft velocity aligned with the commanded frequency. A continuous standstill output of 10.4 Nm allows the axis to hold static process loads without overheating. Accurate mechanical centering is achieved through the 110 mm pilot diameter that aligns the flange with adjoining machine plates during installation. All power and feedback connectors point toward side B, simplifying cable routing when the motor is mounted against a wall. Position reference across multiple turns is delivered by an integrated multi-turn absolute encoder that restores absolute angle data immediately after power is restored. Standard dynamic balancing reduces vibration, and the C length code gives a medium magnetic stack that balances torque production with overall weight.

The model is supplied without a blocking brake, so braking or load holding must be handled by the drive or an external clamp. Communication with the controller uses digital servo feedback, enabling high-resolution commutation and automatic parameter loading. Protection against dust and coolant splash is aided by a shaft seal, which is useful when the standard housing is exposed to lubricants on transfer lines. A plain shaft is provided, and its smooth surface mates with compression couplings while minimizing fretting in reversing service. The standard shaft end is on the drive side, and there is no shaft extension on side B, which helps keep the package length compact in tight machine layouts.
