MDD025B-N-100-N2G-040FB0
The MDD025B-N-100-N2G-040FB0 is a small-frame synchronous motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it supplies high-speed rotary motion to positioning axes and light pick-and-place stations in automated machinery. By converting controlled three-phase electrical power into mechanical torque, the unit forms the electromechanical link between the servo amplifier and the driven load. Its compact frame supports installation on miniature stages and other assemblies where low moving mass and short cycle times are important. That makes it useful for compact handling units, indexing devices, and other servo axes that benefit from fast response.
At a nominal speed of 10000 rpm, the rotor can make rapid revolutions that shorten move times in high-throughput equipment. The continuous torque at standstill is rated at 0.60 Nm, indicating the maximum low-speed torque the motor can deliver without overheating. A centering diameter of 40 mm aligns the housing precisely on the machine interface, helping keep the motor shaft concentric with the driven components. Power and feedback conductors exit on side B, which simplifies wiring when adjacent components limit access to the opposite face. Position data is supplied by resolver feedback, providing rotor angle information with high noise immunity for closed-loop control.
The size code 025 identifies the smallest stator diameter in the MDD lineup, which helps reduce mass and reflected inertia. The rotor uses a standard balancing grade, allowing direct coupling to precision gearheads without excessive vibration. The motor has a plain shaft, which avoids keyway play when a friction hub or clamping element is used. It is supplied without a blocking brake, so any static load holding must be provided by the drive or by an external brake module. The absence of an onboard brake also keeps the rotor assembly simple and avoids adding extra holding components to the motor body.
