MDD025A-N-100-N2G-040MA0
The MDD025A-N-100-N2G-040MA0 is a compact synchronous motor built by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. Designed for digital drive controllers, it serves high-speed positioning axes in packaging machines, pick-and-place gantries, and other cyclic automation where limited footprint and accurate velocity regulation are important. It converts commanded current into controlled rotary motion for short travel moves, indexing steps, and repeatable start-stop operation. Its mechanical envelope follows the series coding and suits compact mounting arrangements in densely packed machine assemblies.
The motor uses a standard housing with standard balancing to minimize vibration at the rated speed of 10000 rpm. A continuous standstill torque of 0.33 Nm allows light loads to be held while motionless without overheating the windings during normal duty. Alignment inside a gearbox or flange is guided by the 40 mm centering diameter, and the power and feedback plugs are on Side A, so cables approach from the front and stay on one side of the machine. A single-piece Connector carries phase, protective earth, and sensor conductors, which keeps the connection layout compact. Size code 025 with length code A indicates a short stator body, and the shaft is supplied without a shaft seal for use in dry, clean interiors. The motor also has a shaft end only on side A, which helps keep inertia low in ultra-compact rotary stages.
Integrated Resolver feedback provides sinusoidal position signals for commutation and speed loops, and it remains compatible with legacy drive controllers that expect this feedback format. Because the unit is supplied without a blocking brake, stopping torque must be generated electrically or by external clamping devices when power is removed. The output shaft uses a keyway profile, which simplifies coupling to timing pulleys or miniature gearheads without relying on shrink fits. This shaft arrangement is useful where compact mechanical transmission parts must be mounted securely and removed without special hub geometry.
