MDD025A-N-100-N2K-040GR1
The MDD025A-N-100-N2K-040GR1 is a compact synchronous servo motor developed by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it serves precision axes where high rotational speed and accurate position control are required. The unit uses a standard housing that supports close mounting inside machinery with limited installation space. Its single drive-side shaft end, with no side B extension, leaves more room for couplings, nearby machine parts, and cable routing.
It supplies a continuous standstill torque of 0.33 Nm, providing steady force to counter small process loads without overheating. When commanded, the rotor can accelerate to 10000 rpm, meeting throughput demands for pick-and-place gantries or spindle positioning tasks. A built-in blocking brake delivers 1.0 Nm of static holding torque, securing vertical or overhung loads during stopping and power-off conditions. Installation is centered by a 40 mm pilot diameter that aligns the stator concentrically with the machine frame and helps reduce vibration. Output motion is transferred through a plain shaft, allowing backlash-free clamping hubs and avoiding stress from a keyed connection.
All power, brake, and feedback leads exit on the right side, and the housing uses a sealed connector interface for a clean plug-in connection. Position data is reported by an integrated absolute encoder, while coarse commutation is provided by resolver feedback, giving the drive both fine position information and a dependable reference signal. A shaft seal helps keep contaminants away from the motor interior, and standard balancing supports smooth operation across the speed range. The compact frame size of 025 and length code A keep mass low, which supports rapid axis response in space-restricted assemblies.
