MDD025B-N-100-N2K-040FA0
The MDD025B-N-100-N2K-040FA0 is a compact synchronous motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for use in digital drive systems where high spindle speed and precise servo regulation are required. By receiving controlled current from a drive controller, the motor generates proportional torque so small automated stations can perform indexing, gripping, and low-inertia transport tasks with repeatable motion. Its compact size also makes it suitable for installations where mounting space is limited and fast motor response is important.
The electrical output profile centers on a nominal speed of 10,000 rpm, allowing the rotor to sustain high cycle rates with minimal cogging. At standstill, the windings deliver 0.60 Nm of continuous torque, which is suitable for holding or slowly accelerating lightweight loads without overheating. All power and feedback conductors exit on side A, so the opposite face can remain clear for airflow or nearby mounting hardware. A sealed circular connector carries the phase, protective earth, and feedback lines, providing a clean connection point in place of hardwired terminations. Position feedback relies on resolver feedback, an analog sensing method that remains tolerant to electrical noise and supports stable servo control across the speed range.
Mechanical mounting is simplified by a 40 mm centering diameter that aligns the stator flange to gearboxes or adapter plates without shims. The housing uses motor length code B, giving the unit a short body that helps reduce total mass while still accommodating the motor’s internal feedback components. Output power is transferred through a plain shaft, which is suited to couplings that do not require a keyed interface. The motor comes without a shaft seal, so the adjacent machine section must provide its own protection if fluids or fine dust are present. The unit is also supplied without a blocking brake, which suits applications where holding force is handled elsewhere in the system.
