Product Description:

The MDD025B-N-100-N2G-040FA0 is a small-frame AC servo motor developed by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it provides high-speed rotary motion for light automation axes, pick-and-place heads, and laboratory equipment. Its compact dimensions suit tight machine spaces, and the motor serves as the electromechanical actuator that turns drive commands into precise shaft movement in closed-loop systems. Integrated feedback lets the controller monitor rotor position continuously and regulate speed during rapid start-stop cycles. This layout is useful where the motor must fit close to guides, tooling, or other moving assemblies without sacrificing controlled motion.

The motor has a rated speed of 10,000 rpm, allowing rapid indexing where short cycle time is important. At standstill, it can deliver 0.60 Nm of continuous torque, so steady holding duty within that value does not overheat the winding. Mechanical alignment is supported by a 40 mm centering diameter that keeps the housing concentric with the mounting surface. Power and feedback leads exit on side A, which can simplify routing when mating cables enter from the same end. The motor size of 025 keeps inertia low and helps the axis respond quickly to acceleration and deceleration commands. The speed range suits applications that favor fast motion and light loads rather than high continuous torque.

The electrical connection uses a connector, and the rotor is balanced to a standard grade for smooth operation at high speed. Because the unit is supplied without a blocking brake, external holding force is required when power is removed. It also ships without a shaft seal, so the installation should be kept away from areas exposed to liquid splash. Motion feedback is provided through resolver feedback, which sends rotor position signals to the drive and remains resistant to electrical noise. The output uses a plain shaft, and there is no second shaft extension, which keeps the coupling arrangement straightforward. A connector-based interface also keeps the motor housing neat by avoiding loose flying leads.
