Product Description:

The MDD025B-N-100-N2K-040ME0 is an AC servo motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. It is built for direct coupling to digital drive controllers, where it delivers rapid rotary motion for tooling, pick-and-place modules, and other high-cycle automation equipment. Its compact 025 frame with B length helps the motor fit into tight machine spaces while still providing the speed response and feedback capability needed for coordinated multi-axis movement. This motor type is well suited to compact handling systems that need fast reversals, low moving mass, and precise synchronization with companion axes.

The motor reaches a nominal speed of 10000 rpm, enabling short cycle times in applications that require very high axis velocity. At standstill, it can sustain 0.60 Nm of continuous torque, which indicates the load it may hold within its thermal limits during continuous operation. That operating profile suits lightweight mechanisms that need quick starts and stops without requiring a larger motor body. Position data is provided by an integrated absolute encoder, while commutation and velocity loops are closed with resolver feedback; this combination supports accurate positioning together with stable phase reference inside the drive. Power and feedback conductors exit through a connecting cable with a coupling unit, which keeps the interface compact and allows straightforward cable separation. Standard dynamic balancing helps reduce vibration, and the housing uses a non-ventilated design so surrounding machine airflow can remove heat. This arrangement keeps the exterior simple and avoids added fan hardware on the motor housing.

A centering diameter of 40 mm aligns the motor on the machine plate, and the electrical connection is located on the left side so cable routing can follow existing harness paths. The unit is supplied without a blocking brake, making it appropriate for systems that hold position through drive torque or external locking devices. Torque is transmitted through a keyway shaft, and the motor has no side B shaft extension or shaft seal, which helps keep friction low in enclosed installations. The output arrangement is intended for direct coupling elements that use positive mechanical engagement.
