Product Description:

The MDD025A-N-100-N2K-040GB0 is a compact synchronous motor from the MDD Synchronous Motors series manufactured by Bosch Rexroth Indramat. Classified for use with digital drive controllers, it generates closed-loop rotary motion for small pick-and-place axes, labeling heads, and other light-duty stations in automated production lines. Its compact frame and integrated feedback hardware support precise regulation of position, speed, and torque during fast, repeatable motion. The motor is well suited to machine sections where mounting space is limited and low moving mass helps keep cycle times short.

At a nominal speed of 10000 rpm, the rotor can complete rapid index cycles while remaining within the thermal limits of its standard housing and A-length frame. Continuous stall torque is 0.33 Nm, which gives the motor enough output for light loads and short travel moves. Power and feedback leads exit on side B, and a single circular connector keeps cable routing compact in tight cabinets or small machine modules. Accurate mechanical alignment is supported by a centering diameter of 40 mm, which helps maintain concentricity between the motor shaft and a coupled pulley, gear, or flexible coupling. A fitted shaft seal helps keep oil or coolant spray away from the internal bearing area during operation.

Position data is delivered through resolver feedback, and an integrated absolute encoder provides single-turn position immediately after power-up. The rotor is balanced to the standard grade, which helps keep vibration low when used with the motor's plain shaft. The design is supplied without a blocking brake, so any holding function must come from the drive or from external mechanical elements when the axis is stopped. This arrangement leaves the shaft free for direct coupling and supports installations that rely on electronic holding control.
