MDD025C-N-100-N2G-040PF1
The MDD025C-N-100-N2G-040PF1 is a compact servo unit from Bosch Rexroth Indramat's MDD Synchronous Motors series. It is supplied as a motor for digital drive controllers, so it integrates directly with Rexroth power modules to create closed-loop axes in pick-and-place robots, small milling heads, or labeling stations. That arrangement supports controlled acceleration, repeatable positioning, and stable speed regulation in compact automation equipment. The motor uses standard dynamic balancing to reduce residual vibration at high speed, which helps keep motion smooth during rapid direction changes.
This model reaches a nominal speed of 10000 rpm, allowing fast indexing where short cycle times are critical. A continuous standstill torque of 0.90 Nm provides usable holding force before rotor heating requires derating. The centering seat diameter is 40 mm, and cables exit toward the right, which can simplify routing when drives are placed on the machine's left side. Position feedback is provided by resolver feedback, which supplies rotor position signals that remain reliable at elevated temperatures and during rapid acceleration. A connecting cable with a coupling unit mates to the motor's fixed connector, and the housing does not need to be opened for cable attachment. Standard housing execution keeps the outer dimensions consistent across the 025 frame family, and the shaft end is supplied without a secondary extension on side B to conserve axial space.
A blocking brake rated at 1.0 Nm secures the load when power is removed, which is useful on vertical axes or stations that must hold position at a stop. A fitted shaft seal helps protect the bearing from coolant splash and fine dust, and the output spindle uses a keyway to limit slip during repetitive start-stop duty. The motor is built in the MDD size 025 with length code C, which adds stack height for thermal mass while keeping overall weight low.
