Product Description:

The MDD025A-N-100-N2G-040GA0 is a compact synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts commanded current into rapid rotary motion for lightweight pick-and-place axes, laboratory feeders, and indexing tables. Its standard housing and balancing configuration allow direct installation on common IEC-compatible flanges, and the plain shaft engages couplings without additional machining. The compact format also suits small moving assemblies where low mass, quick response, and efficient use of installation space are important. It is well suited to dynamic applications that cycle frequently and require dependable rotary motion in a limited footprint.

At its nominal operating point, the rotor reaches 10000 rpm, which helps shorten positioning times in low-inertia mechanisms. A continuous standstill torque of 0.33 Nm allows the axis to hold load without excessive heating during short dwell periods. The rotor uses standard balancing, which supports smooth operation in applications that depend on repeatable motion. All power and feedback terminations face side A, and a single connector simplifies cable routing in confined cabinets. This arrangement keeps cable entry predictable when the motor is installed in closely spaced machine sections. The motor is identified by size code 025 and length code A, which indicate a slim stator profile suited to tight mounting pitches.

The front flange provides a centering recess of 40 mm, ensuring concentric alignment with gearheads or fixtures during installation. Because the unit ships without a blocking brake, static holding must be supplied by the drive or by an external clamp when the axis is stopped. Angular position is relayed through resolver feedback, giving reliable shaft data across the operating range and supporting stable control in electrically noisy environments. The plain shaft uses a shaft seal to limit oil migration and particulate ingress, which helps protect the bearing area and supports cleaner operation in enclosed machinery. This arrangement is useful where nearby lubricants or fine dust could otherwise reach internal parts.
