Product Description:

The MDD025B-N-100-N2G-040MA1 is an AC synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a compact motor for digital drive controllers, it supplies precise rotary motion to axes that require high acceleration and short indexing times in automated machinery. Its permanent-magnet rotor is optimized for fast response, making the unit suitable for packaging, electronic assembly, and other high-speed positioning duties.

The motor delivers a continuous standstill torque of 0.60 Nm, enabling stable force output without overheating when the shaft is locked. When energized, it can reach a nominal speed of 10,000 rpm, which supports rapid-cycle equipment with minimal dwell time between moves. A blocking brake rated at 1.0 Nm is integrated to hold the load when power is removed, and this mechanical retainer can eliminate the need for external clamps on light vertical axes. Position information is returned by resolver feedback, allowing the drive controller to close velocity and position loops even under electrical noise. Mechanical alignment to mating gearboxes is set by a centering diameter of 40 mm, and standard dynamic balancing reduces residual vibration at high speed.

Electrical and feedback leads exit on side A through a single connector, simplifying cable routing in cramped cabinets and keeping resolver and brake lines in the same harness. The housing is made of standard cast aluminum, and the B length code pairs the 025 frame with an elongated stator stack to extend power density without increasing the cross-section. A shaft machined with a keyway transmits torque to couplings, while the primary shaft end is supplied as standard and no shaft emerges from side B, which helps save axial space. Since the unit is supplied without a shaft seal, it should be mounted inside an enclosure where oil spray and coolant intrusion are controlled.
