MDD025B-N-100-N2K-040PC1
The MDD025B-N-100-N2K-040PC1 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Intended for use with digital drive controllers, it transforms commanded current into precise rotary motion for positioning and velocity control in automated machinery. The motor uses size 025 mechanics, features a standard housing and standard balancing, and has a length code B frame that helps conserve space in compact installations. It is suited to tasks that demand repeatable starts, stops, and short positioning moves.
The mechanical interface supports precise alignment and smooth running during repeated motion. The centering diameter is 40 mm, and the shaft is balanced to the standard grade so coupling loads remain even. Power and feedback conductors exit on Side A, and a connecting cable with coupling unit simplifies plug-in installation while keeping the cable entry on one side of the motor. At standstill, the motor delivers a continuous torque of 0.60 Nm, which supports static holding or slow indexing within its continuous operating range. Position data are generated by an integrated absolute encoder. A shaft seal protects the interior against dust or coolant splash.
A blocking brake provides 1.0 Nm of holding torque when the axis is powered down, helping prevent drift on vertical or lightly loaded axes. During motion, the rotor can reach a nominal speed of 10000 rpm, making the motor suitable for high-speed spindles or pick-and-place axes that require fast positioning. The single shaft end follows a keyway profile and ships without a secondary shaft on side B, allowing direct coupling to pulleys or gears while keeping the opposite face clear for mounting hardware. The standard housing, B-length format, and integrated sealing support use in compact enclosed machine spaces.
