Product Description:

The MDD025C-N-100-N2K-040PC0 is an AC synchronous servo motor manufactured by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. As a motor for digital drive controllers, it supplies regulated torque while providing position data to automated axes in assembly stations, pick-and-place modules, and compact feed drives. Its integrated electronics report rotor angle directly to the drive, enabling closed-loop control without external sensors and allowing precise rotary motion in industrial automation.

This model uses a centering diameter of 40 mm, so mounting fixtures can be machined for an exact fit. Power and feedback conductors exit on Side A, reducing cable loops in machines where gearboxes sit on the opposite face. The factory-supplied harness is a connecting cable with a coupling unit, so no additional plugs are required between the motor and the cabinet. During continuous stall, the rotor can deliver 0.90 Nm, which suits light end-effectors or indexing tables. Position information is produced by an integrated absolute encoder, eliminating homing moves after power-up. The motor uses standard dynamic balancing to limit residual vibration. A shaft seal helps block coolant ingress, and the unit is supplied without a blocking brake, so holding force must be provided by the drive or external mechanics.

The rotor can reach 10,000 rpm, giving linear actuators high translational speed when coupled through small-pitch screws. Command signals are processed through resolver feedback, which tolerates electrical noise and high temperatures. The output shaft is machined with a keyway for positive torque transmission, and its length corresponds to code C within the series. The standard housing has a single shaft end on the drive side, which helps reduce overhung mass.
