Product Description:

The MDD025B-N-100-N2G-040FA1 is a compact servo unit from Bosch Rexroth Indramat’s MDD Synchronous Motors series. Designed for closed-loop operation with digital drive controllers, it supplies precise high-speed rotation to light automation axes where space and acceleration margins are tight.

During continuous stall conditions the rotor sustains 0.60 Nm without exceeding rated temperature, while the winding layout supports a top operating speed of 10000 min⁻¹ for rapid indexing cycles. Position feedback is generated by a resolver feedback device, giving analog sinusoidal signals that remain reliable in dusty or oily environments. For power-off holding the motor is fitted with a blocking brake that clamps the shaft with 1.0 Nm of torque, and motion is transmitted through a plain shaft that accepts standard couplings without keyways.

Mechanical interface details further simplify integration. The flange aligns to machinery with a centering diameter of 40 mm, and power and feedback leads exit on Side A through a single keyed connector for quick wiring. Overall length follows the series’ length code B, giving a short footprint that matches the 025 frame size. Standard dynamic balancing reduces vibration, the housing is the series’ general-purpose version, and the absence of a shaft seal means the motor should be mounted in clean zones or protected enclosures.
