MDD025A-N-100-N2G-040PR1
The MDD025A-N-100-N2G-040PR1 is a small-frame synchronous motor in the MDD Synchronous Motors series manufactured by Bosch Rexroth Indramat. Designed for digital drive controllers, it supplies fast, repeatable rotary motion on precision axes in assembly stations and electronic component placement systems. It also suits light machining cells where compact motor size and high operating speed are required.
This model delivers a continuous standstill torque of 0.33 Nm, providing modest holding force while minimizing heat at zero speed. Its top operating velocity is 10,000 rpm, enabling high-throughput positioning when paired with a compatible inverter. The frame uses size 025, and the stator stack uses length code A, which keeps mass and inertia low for rapid acceleration. A centering diameter of 40 mm simplifies concentric mounting on gearboxes or flanges, while standard balancing helps limit residual vibration during high-speed operation. Rotor position is returned to the controller through resolver feedback, which tolerates electrical noise and supports smooth velocity control. Power and feedback leads share a cable arrangement that helps keep routing orderly inside multi-axis cabinets.
The housing is a sealed standard design that includes a shaft seal, so lubricant stays inside and airborne contaminants remain out. For vertical or suspended loads, the motor is supplied with a blocking brake that can hold the shaft to prevent drift when power is removed, and its static capacity is 1.0 Nm. Both the power and encoder conductors plug into a single connector that matches the series pinout, and the cable exit is oriented on the right side to clear adjacent hardware. A keyed shaft end is provided without a second shaft on side B, which eases coupling alignment and helps prevent slip under peak torque.
