MDD025C-N-100-N2G-040PR1
The MDD025C-N-100-N2G-040PR1 is a compact AC servo unit manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Built for digital drive controllers, it converts drive output into high-speed rotary motion for closed-loop axes used in pick-and-place systems, small conveyors, and labeling spindles. Its standard housing and rotor balancing support repeatable acceleration and position accuracy while keeping vibration low in compact machine assemblies. This layout suits machinery that needs fast response, stable motion, and dependable tracking in a small installation space.
At standstill, the motor can deliver a continuous torque of 0.90 Nm, allowing it to hold loads without overheating while awaiting the next command from the controller. When energized, it reaches a nominal speed of 10000 rpm, so light-duty positioning tasks may not require a gear stage. Position information is provided through resolver feedback, which helps the drive maintain accurate control during rapid reversals. The integrated blocking brake supplies 1.0 Nm of holding torque to prevent shaft movement when power is removed. A shaft with a keyway transmits torque positively to couplings or pulleys, and a shaft seal helps keep lubricants and contaminants separated.
The motor uses a centering pilot of 40 mm to align the housing on adapter plates and machine mounts. Power and feedback plugs exit on the right side, and the standardized connector interface helps simplify cable routing in tight spaces. The motor has a frame size of 025, which places it in the small-frame range of the MDD family. It has a standard shaft end on side A, and the lack of a side-B extension helps reduce overall length inside compact enclosures. This arrangement leaves more room near the coupling area when the motor is installed in narrow machine sections.
