Product Description:

The MDD025B-N-100-N2G-040PL1 is a synchronous servo motor from Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. It is intended for use with digital drive controllers, converting controlled current into repeatable rotary motion for tasks such as feeder rolls, miniature gantries, and indexing fixtures. Within an automated cell, it acts as the mechanical actuator that follows the velocity and position commands generated by the associated controller. Its compact format suits applications where installation space is limited but precise servo response is still required.

The motor uses size code 025 and length code B, while the flange centers on a 40 mm diameter that fits standardized mounting patterns. This centering diameter helps align the motor accurately with matching machine surfaces and compact transmission components. During static operation, the rotor can deliver a continuous standstill torque of 0.60 Nm, and under rated excitation it reaches a nominal mechanical speed of 10000 rpm. Standard balancing limits residual vibration so the motor can be coupled directly to precision gear trains without additional damping, and a keyed shaft end with a factory-fitted shaft seal helps prevent lubricant migration into the stator cavity.

A blocking brake is integrated, and it provides 1.0 Nm of holding torque when the drive is disabled or during emergency stops. Power and feedback conductors are routed through a single industrial connector on the left side of the housing, which helps keep cable routing compact in tight cabinets. Rotor position is returned through resolver feedback, enabling closed-loop regulation at high speeds without the fragility of optical encoders. The motor uses a cast-aluminum housing, and the keyed shaft is supplied without a side B extension, which shortens the overall package for closely spaced axes on a shared machine frame.
