Product Description:

Bosch Rexroth Indramat manufactures the MDD025B-N-100-N2K-040FC0 within the MDD Synchronous Motors series. It is a motor for digital drive controllers and is suited for rapid speed regulation in compact automation axes. A standard housing encloses the stator, and the rotor is balanced to a standard grade for stable running during normal operation. Integrated feedback provides position data to the associated servo drive during high-cycle motion. This layout supports compact axes where repeatable response matters in continuous production tasks with limited installation space.

The mechanical interface uses a centering diameter of 40 mm, which fits directly into matching clamp plates. Electrical and feedback conductors exit on Side A, and the stator windings are prewired to a connecting cable with coupling unit that allows quick connection without terminal screws. With motor length code B, the rotor can produce a continuous standstill torque of 0.60 Nm while maintaining thermal equilibrium. Under rated excitation, the rotor reaches a nominal speed of 10,000 rpm, which suits small spindle and pick-and-place drives. The cable arrangement also helps keep wiring compact in confined machine layouts. This routing can simplify cable runs near moving machine parts.

The motor uses resolver feedback, which provides angle data with good immunity during dynamic operation. Because the motor is supplied without a blocking brake, holding position during power-off states requires controller torque or an external clamping device. The drive end uses a plain shaft, and the motor does not have a side-B shaft end. No mechanical lip seal is fitted, so the unit operates without a shaft seal and is best used in clean zones or with external sealing. The compact 025 frame size helps the motor fit into tight multi-axis assemblies.
