Product Description:

The MDD025B-N-100-N2G-040MF1 is a small-frame synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is designed for use with digital drive controllers in compact automation systems that require fast, repeatable motion. The unit converts commanded current into precise mechanical rotation for positioning and speed control tasks in assembly equipment, packaging machines, and semiconductor handling applications. Its compact format makes it suitable for axes where installation space is limited and rapid response is important. This motor can be used for both positioning duties and speed-regulated operation, depending on the paired drive.

At its nominal operating point, the rotor turns at 10000 rpm, a speed that suits high-frequency drive output while helping keep rotor inertia low for quick response. During standstill, the windings can deliver 0.60 Nm of continuous torque, allowing the axis to resist external load without excessive heating. A blocking brake integrated on the non-drive end adds 1.0 Nm of static torque when power is removed. Position feedback is provided through resolver feedback, which supplies rotor angle signals that remain reliable in electrically noisy environments. Power and signal conductors exit on the right side of the housing, and the shaft uses a keyway to transfer torque to pulleys or couplings without slip.

In mechanical construction, the motor uses the manufacturer's standard balancing grade, so it can be mounted without additional field correction when the centering pilot seats against the machine face. The centering pilot is held to 40 mm, which helps align the motor with compact gearheads and mounting faces in small-axis assemblies. Electrical termination is handled by a connecting cable with coupling unit, so the housing does not rely on a large fixed connector. Because the model is supplied without a shaft seal, it is better suited to protected installations where fluid ingress is controlled. Frame designation 025 and length code B identify the compact build size, and the standard shaft end omits a side-B extension to keep the motor body short.
