MDD025A-N-100-N2G-040GA0
The MDD025A-N-100-N2G-040GA0 is a small-frame synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts inverter commands into mechanical rotation for light-duty industrial axes that require rapid positioning. The motor is intended for systems that use digital servo control to regulate speed and position in real time. That makes it suitable for compact automation equipment where short moves, frequent starts and stops, and repeatable response are more important than heavy load handling.
This model has a nominal speed of 10000 rpm, allowing short cycle times in pick-and-place stages and spindle-related tooling. At standstill, it provides 0.33 Nm of continuous torque, which fits applications that emphasize speed over stall force. This combination supports quick indexing duties where peak speed matters more than high holding torque. Rotor position is reported through resolver feedback, giving analog sinusoidal signals that the drive converts into precise angle data across the full speed range. A centering diameter of 40 mm locates the housing against the machine plate so the motor axis stays aligned with the driven equipment. Electrical connection is made through a single connector, which keeps wiring compact and simplifies cable routing.
The motor’s wiring exits on Side A, keeping power and feedback connections clear of adjacent hardware in compact installations. The output uses a plain shaft, so torque is transferred through clamp or press-fit elements rather than keys. The motor is supplied with a shaft seal, which helps limit contaminant entry at the output end. It is also supplied without a blocking brake, so holding force must be provided by the drive or by external mechanics when the axis is stopped. Additional identifiers include motor size 025, length code A, and a standard shaft end on the drive side only, which keeps the layout consistent with compact servo applications.
