Product Description:

The MDD025A-N-100-N2K-040FA1 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is designed for use with digital drive controllers and supplies regulated rotary motion to compact axes, pick-and-place heads, and other light-load positions in automated equipment. By combining permanent-magnet excitation with closed-loop feedback, this unit converts controller commands into precisely metered torque and speed for responsive positioning tasks on assembly lines or small handling stations.

The mechanical interface begins with a centering diameter of 40 mm. This feature registers the housing to the machine frame so the motor shaft stays coaxial with the driven load. Power and feedback conductors exit on Side A, which keeps cabling on the same face as adjoining actuators in compact installations. A keyed Connector handles all electrical terminations and allows quick connection at the motor. At standstill, the motor can deliver 0.33 Nm of continuous torque, which is enough to hold small tooling in position while remaining thermally stable. Once running, it can reach 10,000 rpm, providing high peripheral speed for rapid indexing duties. Balancing and housing are standard for this model. Because the shaft has no seal, the mounting cavity must remain free of fluid ingress.

Rotor position is tracked by an integrated feedback chain that combines an integrated absolute encoder with resolver feedback for compatibility with legacy drives. A blocking brake rated at 1.0 Nm keeps the axis fixed when power is removed. The shaft end uses a Plain shaft design and is supplied only on the drive side to reduce overhang mass. Motor length code A and size 025 keep the overall footprint short, which helps the unit fit compact axis layouts. This combination of feedback and braking supports stable positioning in small automated systems where space is limited.
