MDD025B-N-100-N2G-040FR0
The MDD025B-N-100-N2G-040FR0 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended to operate with digital drive controllers in automated equipment that demands compact construction and high rotational speeds. By translating drive commands into controlled rotation, it serves positioning and velocity control roles in pick-and-place stations, light conveyors, and auxiliary spindle axes. Its compact format helps it fit installations where available motor space is limited. The motor is also suitable for applications that require repeatable motion during short and frequent operating cycles.
Its mechanical interface includes a centering flange diameter of 40 mm, providing repeatable alignment to gearboxes or mounting plates. The rotor can sustain 0.60 Nm of continuous stall torque, which is useful when matching the motor to the driven load. A nominal running speed of 10000 rpm supports rapid cycle duties when the inverter supplies the required frequency. Power and feedback leads exit through a connector on the right side, which helps keep cable routing orderly in tight machine layouts. Position data is returned through resolver feedback, which offers reliable angle detection in electrically noisy environments. The motor is delivered without a blocking brake, so any required holding function must be provided by motor torque or an external device.
The rotor uses a plain shaft and comes with a standard shaft end that leaves side B blank, saving axial space. Frame dimensions match the 025 size code, and the stator depth follows the B length code for a compact envelope that helps reduce reflected inertia on the load. Standard balancing helps limit vibration during high-speed operation, and the standard housing supports convection cooling inside enclosed cabinets. There is no shaft seal, so the motor should be mounted away from liquid ingress and heavy contamination. A single molded connector carries power and sensor leads, and the motor connects directly to compatible digital controllers.
