Product Description:

The MDD025A-N-100-N2K-040MA1 is a compact AC synchronous motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it forms the active axis element in pick-and-place units, small gantries, and other motion modules that rely on electronic commutation. By combining permanent-magnet excitation with integrated feedback, the unit allows the connected controller to monitor shaft position accurately during operation and support tightly coordinated multi-axis moves.

At the mechanical interface, a centering diameter of 40 mm ensures concentric alignment with gearheads or mounting flanges, while all power and feedback conductors exit on side A, simplifying cable routing in dense cabinets and keeping bend radii predictable. During static operation, the rotor can deliver 0.33 Nm of continuous torque, enough for light-load clamping and precision indexing. When accelerated, it can reach a nominal speed of 10,000 rpm, so short linear strokes can be completed in fractions of a second. The integrated blocking brake adds 1.0 Nm of holding torque, maintaining position on vertical axes without energizing the winding and reducing heat buildup during standby.

Standard dynamic balancing minimizes vibration at high speed, and the motor’s slim A-length body pairs with connector-style terminals to reduce enclosure depth. Motion feedback for servo regulation is provided through absolute encoder feedback, which supports precise position monitoring by the drive. The single shaft end uses a keyway for positive drive coupling, and it is assembled without a shaft seal, so the installation must avoid fluid ingress or use an external seal. The motor has a standard housing, a size code of 025, and a length code of A. These codes indicate its overall stack height relative to other motors in the series.
