MDD025C-N-100-N2G-040FL1
The MDD025C-N-100-N2G-040FL1 is a compact synchronous motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It serves as the rotary element for digital drive controllers, converting drive current into rapid rotary motion for positioning and follow-up axes in automated machinery. Its compact format suits small servo applications where low moving mass and quick response are important for accurate cycle timing. This type of motor is commonly used on compact handling units and light indexing mechanisms that need quick reversals and stable speed control.
At a nominal speed of 10000 rpm, the rotor can reach ten thousand revolutions per minute under rated voltage and load, permitting fast traverse motion on lightweight actuators. At standstill, the electromagnetic system supplies 0.90 Nm of continuous torque, allowing static positioning without overheating. When the blocking brake is engaged, it secures the shaft with 1.0 Nm of torque so suspended loads remain stationary after power is removed. The flange has a centering bore of 40 mm for accurate alignment on adjoining machine surfaces. Power and feedback conductors exit on the left side through a single multipole connector, which keeps cabling compact during installation. This arrangement keeps the motor face clear for direct mounting and reduces the amount of free cable needed near the housing.
The motor uses frame size 025 with length code C, giving it a short body that helps limit inertia on small gantries and other compact axes. Internal resolver feedback provides rotor position data with strong noise immunity, allowing stable closed-loop control across the speed range. A plain shaft without a side-B extension mates directly to miniature couplings. The housing is standard, and the motor is built without a shaft seal, so any required external protection must be provided by the surrounding machine design. The short housing also helps the motor fit into tight machine spaces where larger servo packages would be difficult to place.
