Product Description:

The MDD025B-N-100-N2G-040GC1 is a small-frame synchronous motor from Bosch Rexroth Indramat in the MDD Synchronous Motors series. It is intended for digital drive controllers and converts commanded current into rotary motion for precision industrial axes. The standard housing supports cabinet installation, and the plain output shaft transmits torque directly to couplings or small gear stages. This layout fits compact motion assemblies where quick response and high rotational speed are needed without a large motor footprint.

At standstill, the motor can deliver a continuous torque of 0.60 Nm, which supports static loads and closed-loop current control. During normal operation, its rotor reaches a nominal mechanical speed of 10,000 rpm, allowing a wide speed range with the matching drive module. This high operating speed suits small spindles and light positioning axes that require smooth velocity control. An integrated blocking brake rated for 1.0 Nm holds vertical loads when power is removed. The centering pilot on the flange measures 40 mm in diameter for concentric alignment, and the power and feedback cables exit on side A to simplify routing in narrow enclosures.

The mechanical layout is balanced to the standard grade, so additional vibration correction is usually unnecessary in light-duty assemblies. The motor has a frame size of 025 and a length code of B, which keeps the housing short while preserving enough space for the winding. The front end is supplied with a shaft seal to limit oil ingress, and the plain shaft form avoids keys that could trap debris. Position data is returned through resolver feedback, which resists temperature changes and electrical noise better than optical devices. A connecting cable with coupling unit supports installation, and the single-ended shaft arrangement does not include a side-B shaft end.
