MDD025B-N-100-N2K-040PC0
The MDD025B-N-100-N2K-040PC0 is a brushless synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts commanded current into controlled rotary motion for positioning and velocity loops in automated machinery where repeatable response is important. Its construction follows the standard housing layout of the series, allowing the motor to fit compact machine frames while meeting the thermal limits expected in modern automation.
Under continuous stall conditions, the rotor produces 0.60 Nm of torque, which provides holding force for energized static loads or low-speed indexing. When driven by a suitable inverter, the motor reaches a nominal speed of 10000 rpm, making direct coupling to miniature spindles practical. Accurate position data come from an integrated absolute encoder, so the drive can read position immediately after power-up. The unit is delivered without a blocking brake, so power-off holding must be supplied externally. For concentric mounting, the flange provides a 40 mm centering diameter that mates with precisely machined fixtures.
Power and signal leads exit on Side A through a connecting cable with a coupling unit. The standard housing encloses the stator without auxiliary cooling channels, and the B length code keeps the overall depth short for compact installations. The frame corresponds to 025 size, and standard balancing keeps rotor mass low for rapid acceleration. A shaft seal protects the front bearing from oil or dust ingress, and the output end uses a keyway to transmit torque; there is no shaft extension on the rear face. For drive synchronization, the feedback channel supplies resolver feedback, providing analog angle data that remains reliable in electrically noisy environments.
