Product Description:

The MDD025B-N-100-N2G-040MR0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for use with digital drive controllers in pick-and-place stations, small gantries, or indexing tables that need rapid acceleration, accurate velocity regulation, and a compact footprint. By converting electrical power into controlled rotary motion, the motor supports closed-loop torque production so the associated controller can regulate position and speed with consistent response. Its compact design suits light-duty axes where installation space is limited and controlled motion must remain precise through frequent starts and stops.

A centering recess of 40 mm positions the flange accurately, while the shaft uses an ISO keyway profile for torque transfer to couplings or small gear inputs. Power and feedback leads exit on the right side, and the housing uses a single connector, which keeps cable routing straightforward in tight machine layouts. Standard housing construction and standard dynamic balancing support stable operation at the rated 10000 rpm nominal speed. Under stall conditions, the motor delivers a continuous torque of 0.60 Nm for constant-load operation, and the design is supplied without an additional shaft end on side B.

Rotor position is reported through resolver feedback, enabling sinusoidal commutation and stable velocity control by the drive. The motor is supplied without a blocking brake, so applications that require holding force at standstill must rely on an external mechanical device or drive-controlled torque. The output shaft has a keyway and does not include a shaft seal, which makes the motor better suited to clean installation areas rather than locations exposed to coolant spray. The 025 frame size keeps the package compact while allowing direct use with Rexroth DDS and similar amplifiers.
