MDD025A-N-100-N2G-040PE0
The MDD025A-N-100-N2G-040PE0 is a synchronous servo motor from Bosch Rexroth Indramat in the MDD Synchronous Motors series. It is intended for digital drive controllers on compact positioning axes, where a small motor package is needed for fast response and limited installation space. The unit uses a standard housing with the A-length, size-025 frame, so it fits light-duty stages while keeping the overall footprint small. This layout suits machines that need accurate servo regulation without using a larger motor body than necessary. It also uses a standard shaft end, and there is no secondary shaft on side B.
The motor can maintain a nominal speed of 10000 rpm, giving high surface velocity on small-diameter loads. At standstill, it provides 0.33 Nm of continuous torque for steady holding and low-speed motion. A centering diameter of 40 mm supports accurate alignment to a gearbox or mounting flange. Torque is transferred through a keyway, which helps prevent slip between the motor shaft and the driven component. Motion feedback is supplied by resolver feedback, which provides sinusoidal position signals suited to servo control under vibration and elevated temperature. This feedback arrangement allows the connected drive to track rotor position continuously and respond smoothly to changing load conditions.
Cabling exits on the Left side, which can simplify routing when the motor is installed in tight axis layouts. A connecting cable with a coupling unit allows quick disconnection without changing the motor housing. The motor is supplied without a blocking brake, so any holding force at standstill must come from the drive or from an external mechanical device. A shaft seal helps protect the internal bearings from coolant splash and airborne contaminants when the motor is used near fluids or fine debris. Rotor balance is specified as Standard balancing, which supports smooth running during continuous high-speed operation and helps limit vibration at the shaft. The cable exit arrangement can also be useful where nearby guards, covers, or machine plates leave only limited connector clearance.
