Product Description:

The MDD025A-N-100-N2K-040FF0 is a compact synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it provides rotational positioning and velocity control on tightly integrated machine axes where small frame dimensions are required. The motor follows size 025 and length code A dimensions, giving it a short overall body while preserving the centering interface used across the series. It has a standard housing and relies on dynamic servo regulation instead of an internal brake for position holding.

Under continuous stall conditions, the rotor can deliver 0.33 Nm of torque, which indicates the steady-state load the motor can support under rated cooling and ambient conditions. When the drive issues full excitation, the motor can accelerate quickly toward its nominal speed of 10000 rpm, a rating suited to high-throughput spindles or pick-and-place heads. Mechanical alignment to the mounting flange is aided by a centering diameter of 40 mm, and cable exits are oriented to the right side to simplify routing in dense cabinets. Power and feedback conductors share a connecting cable with a coupling unit, reducing plug count and helping protect high-frequency signals from external noise. Rotor position is provided by an integrated absolute encoder, so the controller receives position data immediately after power-up.

The motor uses a standard balancing grade, which helps keep residual vibration low for miniature bearings. Its output interface is a plain shaft without a side B extension, supporting direct coupling where a simple shaft form is preferred. Because the unit is supplied without a shaft seal, it should be installed in clean, dry areas or used with protective covers if fluid splash is expected. The design also omits a blocking brake, so back-driving is possible in applications that rely on external holding devices.
