MDD025C-N-100-N2K-040ME1
The MDD025C-N-100-N2K-040ME1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat in the MDD Synchronous Motors series. It is intended for connection to digital drive controllers, where it converts commanded current into rotary motion for automated machinery. The permanent-magnet rotor and compact housing support high acceleration on small gantries, feeders, and spindle units while keeping the installation footprint small. Because the motor is built for servo operation, it can support precise starts, stops, and short indexing moves in compact automation equipment.
The permissible top speed reaches 10000 rpm, so the shaft can follow motion profiles suited to high-speed assembly or light grinding processes. At standstill, the motor produces 0.90 Nm of continuous torque, which helps an axis hold position during controlled operation. A 40 mm centering diameter aligns the flange with adjoining mechanics to reduce runout during installation. Power and feedback leads exit on the left side, which can simplify cable routing in enclosures organized for lateral service loops. Position data are supplied by an integrated absolute encoder, allowing the controller to read shaft position immediately after power-up. This feedback arrangement also removes the need for a reference run after each restart in many motion applications.
For shutdown conditions that require mechanical locking, the integrated blocking brake supplies 1.0 Nm of holding torque. The motor uses frame code 025 with stator length C, which gives a compact form for tightly spaced machine layouts. Torque is transmitted through a keyway shaft, and the lack of a shaft seal reduces drag at higher speeds. The supplied connecting cable and coupling unit support direct connection to compatible digital drive systems, and the dynamically balanced rotor helps maintain smooth running in rapid motion cycles.
