Product Description:

The MDD041B-N-100-N2K-050PB1 belongs to the MDD Synchronous Motors series manufactured by Bosch Rexroth Indramat. It is a compact servo motor intended for digital drive controllers. It supports precise position and velocity control on fast-cycling machine axes within industrial automation.

This model uses a size 041 frame and the B length code, giving a small envelope that still delivers a continuous standstill torque of 1.35 Nm. The rotor is dynamically balanced to the factory’s standard grade, so additional field trimming is usually unnecessary. Rated speed reaches 10000 rpm, allowing rapid traverse moves when paired with matching drive electronics. Mechanical alignment during mounting is aided by a centering diameter of 50 mm. Power and feedback connectors are oriented on side B, simplifying cable runs in cabinets where the motor projects forward. A single multi-pin connector handles the electrical interface, reducing wiring time and minimizing connection faults. The housing follows the standard MDD enclosure profile, and the shaft is supplied only on the drive end, avoiding projections on the opposite side that could interfere with adjacent components.

An integrated blocking brake supplies short-term holding torque of 1.2 Nm, so vertical or indexing loads remain stationary when the drive is disabled. Position data is provided by an absolute encoder, while velocity and commutation information are delivered through resolver feedback, enabling high-resolution control loops without external sensors. Rotary power is transferred through a keyway shaft, a form favored for repeatable coupling alignment. Contaminant ingress at the output end is limited by a dedicated shaft seal, supporting reliable operation in typical plant atmospheres. Because the motor is intended for digital drive controllers, its electrical and feedback interfaces match the command protocols and diagnostic functions found in those control platforms, ensuring seamless integration.
