MDD025B-N-100-N2G-040ME0
The MDD025B-N-100-N2G-040ME0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Intended for digital drive controllers, it converts electrical energy into precise mechanical rotation so automated axes can position, follow velocity profiles, or hold loads with closed-loop control. It is intended for applications where the controller must regulate torque and speed smoothly during frequent motion changes. Its compact format suits small motion axes that need repeatable starts, stops, and speed changes in limited installation space.
The unit delivers a continuous standstill torque of 0.60 Nm, giving the drive a predictable holding force during dwell periods and low-speed positioning. Under rated excitation, the rotor reaches a nominal speed of 10000 rpm, supporting high cycle rates in small-format handling equipment and fast indexing tasks. Mechanical referencing is provided by a 40 mm centering diameter that fits standard flange hardware and helps align the motor on the machine face. All power and feedback conductors exit on the left side through a connecting cable with a coupling unit, which eases routing when the motor is mounted close to cabinet walls. The frame follows the standard housing pattern and uses the length code B envelope, which helps it fit compact servo assemblies. The motor is supplied without a blocking brake, so any load that must remain fixed at standstill needs an external holding method.
Position data is returned through resolver feedback, providing rotor angle signals across the full speed range for stable commutation and motion control. The shaft uses a keyway interface and is single-ended, while the lack of a shaft seal lowers drag in clean, enclosed machines. The single-ended shaft layout also keeps the output side straightforward for couplings and small belt drives. Size code 025 keeps inertia low, and standard balancing minimizes vibration as the motor runs through its upper speed range. Lightweight pick-and-place modules, compact printing stations, and other small automated systems can use this motor where quick response is needed.
