MDD025B-N-100-N2K-040PD0
The MDD025B-N-100-N2K-040PD0 is a synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed as a drive element for digital drive controllers, the unit converts commanded current into rapid rotary motion for positioning tables, lightweight pick-and-place axes, and other high-speed automation modules. It is intended for closed-loop systems that rely on servo feedback for speed and position correction during dynamic motion. Its compact format suits small machine modules where low moving mass and fast response are important for repeatable operation. The motor uses mechanical dimensions and electrical interfaces that allow direct pairing with Indramat servo amplifiers without special mechanical changes.
This model has a nominal speed of 10000 rpm, allowing high cycle rates where short indexing times are critical. When the rotor is energized but stationary, it can deliver a continuous standstill torque of 0.60 Nm, which indicates how much static load the axis can hold without overheating. Accurate mechanical alignment to the machine frame is aided by a centering diameter of 40 mm. Power and feedback connectors are positioned on Side B of the housing, which helps keep cable routing predictable in compact installations. Torque is transferred through a shaft machined with a keyway, providing a positive coupling to pulleys or gear sets used on fast-moving axes.
Rotor position is captured by an integrated absolute encoder, supplying single-turn data to the drive so that commutation can resume immediately after power cycling. For applications that use analog resolver processing, a secondary channel provides resolver feedback for compatibility with legacy controller cards. The motor is supplied without a blocking brake, so holding force must come from the drive or an external clamp when power is removed. To protect the internal bearings from coolant or dust, the front output shaft is fitted with a shaft seal, which helps keep contamination out of the internal compartment and supports use in equipment where splash or airborne debris may reach the motor face.
