Product Description:

The MDD025B-N-100-N2K-040ML0 is a brushless synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It serves as the rotary element in digital drive systems, converting commanded current from the controller into precise motion for compact handling modules, feeders, and measuring axes. The motor’s small frame, integrated feedback, and high thermal loading capacity allow it to sustain rapid acceleration while maintaining the position accuracy required in industrial automation tasks. Its design favors low rotor inertia, so velocity setpoints can be reached quickly. This makes the unit suitable for axes that need quick starts, stops, and repeatable positioning in compact machine spaces.

The motor uses a 40 mm centering diameter, which aligns the housing in precision mountings and helps maintain concentricity between the motor and the driven machine. All power and feedback conductors exit through a connection on the left side, which can simplify cable routing in narrow cabinets. Under continuous stall conditions, the rotor can develop 0.60 Nm of continuous standstill torque, which suits lightly loaded spindles or pick arms that must hold position without additional gearing. When commanded at rated frequency, the shaft reaches a nominal speed of 10,000 rpm, allowing short cycle times in high-throughput stations.

Position data is delivered by an integrated absolute encoder, while resolver feedback can also be used for supplementary monitoring. The motor has length code B and a motor size of 025, which give it a short axial length and low mass for fast acceleration. Torque is transferred through a keyway shaft, and the unit is supplied without a blocking brake, so holding force must be provided externally when power is removed. The housing uses a standard design with standard balancing grade and connector terminals, and it has no shaft seal or side-B shaft extension.
