Product Description:

The MDD025B-N-100-N2G-040PC0 is a synchronous AC servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Built for digital drive controllers, it supplies closed-loop rotary motion for compact industrial axes where precise speed regulation and quick accelerations are essential. Its size 025 frame and length code B keep dimensions small, which supports dense multi-axis mounting in compact machinery. A standard housing and standard rotor balancing support smooth operation across the rated speed range during continuous servo duty.

The mechanical interface uses a centering diameter of 40 mm, which helps the motor seat concentrically against the driven load during mounting. The rotor can sustain a nominal speed of 10000 rpm, enabling high-cycle positioning with low-inertia components. At standstill, it delivers a continuous torque of 0.60 Nm, so small fixtures can be held without supplementary gearing. Service cables exit on Side A, and the power and feedback conductors are bundled in a connecting cable with a coupling unit. This layout keeps external connections compact and supports orderly cable routing in confined spaces.

Position data is returned through resolver feedback, which allows the drive to calculate real-time rotor angle and maintain stable commutation during rapid acceleration. Because the motor is supplied without a blocking brake, holding force must be provided electrically by the drive or mechanically by the machine during power-off states. A fitted shaft seal protects the internal bearings from coolant splash, and torque is transmitted through a keyway connection on the standard shaft end. The motor has no side-B shaft extension, which helps preserve a compact envelope where closely spaced axes are required.
