MDD025A-N-100-N2G-040FR0
The MDD025A-N-100-N2G-040FR0 is a compact synchronous servo motor produced by Bosch Rexroth Indramat for use with digital drive controllers in the MDD Synchronous Motors series. Designed as a high-speed actuator, it converts drive output into mechanical rotation for positioning tasks, pick-and-place axes, and light auxiliary duties where space is limited. The housing follows the standard enclosure style, so the mounting interfaces and outer dimensions match other motors in the series. Its compact format also suits installations where low moving mass and fast axis response are important.
This model reaches a nominal speed of 10000 rpm, allowing rapid cycle times when paired with an appropriately rated inverter. At standstill it can deliver 0.33 Nm of continuous torque, which is the steady load it may hold without overheating. Position data is returned through resolver feedback, giving the drive the analog angle signals needed for closed-loop speed and position control. Power and signal conductors enter through a keyed connector mounted on the right side of the housing, which helps when cables must be routed through narrow machine spaces. That cable exit arrangement keeps the connection area on one side of the motor and supports cleaner routing inside compact equipment. Standard balancing is used for the small 025 frame and the short A length, helping the motor run smoothly at high rotational speed.
Machine integration includes a centering diameter of 40 mm, which fits precision spigots for repeatable alignment during installation. The load is driven through a plain shaft in a standard single-ended arrangement, so couplings or pulleys mount on one side only. Because the motor is supplied without a blocking brake, any holding force during power-off conditions must come from external mechanics or controlled servo torque. The design is also without a shaft seal, which reduces friction but limits use in areas exposed to coolant spray or fine dust. It is intended for clean, enclosed automation spaces where contamination is limited and very high rotational speed is required.
