Product Description:

The MDD025B-N-100-N2K-040GC1 synchronous motor is produced by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. Intended for digital drive controllers, it converts drive current into tightly regulated rotation for compact automation axes such as pick-and-place heads or miniature conveyors. Its 025 frame and standard housing help it fit small machine layouts where available space is limited. Standard balancing helps reduce vibration during rapid positioning near sensors, guides, or lightweight tooling. This makes the motor suitable for short-stroke handling modules and small transfer mechanisms that rely on repeatable starts and stops.

At the mechanical interface, a centering pilot of 40 mm aligns the motor with gearboxes or flange adapters. All conductors exit on side A through a connecting cable with a coupling unit, which keeps the electrical connection in one location and simplifies cable routing. The rotor provides a continuous standstill torque of 0.60 Nm, allowing the axis to resist light static loads without excessive heat rise. When commanded, the shaft can reach 10000 rpm, supporting rapid duty cycles in indexing or scanning tasks. Standard dynamic balancing helps limit residual unbalance at high speed. Motor size 025 and length code B keep inertia and mass low, while the standard housing includes a shaft seal to help block lubricant ingress. A plain output shaft without a side B extension suits direct clamp couplings. Low inertia also helps the motor respond quickly when the application changes speed frequently.

Position holding is provided by a blocking brake with 1.0 Nm of static torque. Precise rotor angle data comes from an integrated absolute encoder, and complementary resolver feedback supports compatibility with legacy drive systems. The sealed output uses a plain shaft, which avoids key-related backlash and suits direct-coupled arrangements. Absolute position is available as soon as the control system powers up, so the axis can return to operation without a homing routine. The brake helps hold the axis in place when power is removed or the system is brought to a stop. This combination supports closed-loop motion on compact axes that require secure stopping and immediate position availability.
