MDD025A-N-100-N2G-040MD1
The MDD025A-N-100-N2G-040MD1 is a small-frame synchronous motor engineered by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed for digital drive controllers, it delivers precisely commanded motion for light-duty axes in assembly cells and laboratory automation. The frame size 025 and A-length housing make it suitable where space is limited, and its standard dynamic balancing helps keep vibration low during high-speed positioning. This compact format also works well in installations where nearby sensors, slides, or fixtures leave little room around the drive package.
This model produces a continuous standstill torque of 0.33 Nm, supporting light holding duty without external gearing. When energized, it can reach a nominal speed of 10000 rpm, which supports short indexing times in pick-and-place equipment. A centering diameter of 40 mm aligns the motor precisely on a machine flange to maintain concentricity between the rotor and the driven shaft. The integrated blocking brake applies 1.0 Nm of holding torque, preventing back-driving when power is removed from vertical or suspended loads. Rotor position is monitored through resolver feedback, giving the drive continuous angular data even during rapid acceleration. That feedback supports stable closed-loop speed and torque control when load conditions change during short operating cycles.
Cabling exits on side B, so electrical terminations remain clear of other machine elements. Power and feedback lines are supplied as a connecting cable with a coupling unit, reducing installation errors and limiting the number of separate connector parts. The single output shaft uses a keyway to transmit torque to pulleys or couplings without slip, and the motor is manufactured without a shaft seal, which suits clean, dry environments where fluid exposure is limited. The layout also keeps the cable outlet and shaft interface straightforward for compact machine assemblies where routing space is restricted.
