Product Description:

The MDD025A-N-100-N2G-040FR0 is a compact synchronous motor built by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Intended for direct coupling to digital drive controllers, the unit delivers rapid speed changes and precise shaft positioning for light automation stages and pick-and-place mechanisms. Its mechanical envelope follows the 025 frame code, and the A-length build keeps mass low so that small gantries and feeders can mount the motor without adding significant inertia. Its low-mass format also helps reduce the load placed on small slides and couplings during frequent start-stop motion.

In mechanical terms, the motor body is balanced to a standard grade, and the centering pilot measures 40 mm to align the flange accurately against gearboxes or bracket plates. Power and feedback conductors exit on the right side through a keyed connector, which helps keep cable routing controlled in narrow cabinets or closely spaced machine sections. At the rotor, the design supplies a continuous standstill torque of 0.33 Nm, enough for light holding duties, while a nominal speed capability of 10,000 rpm supports high-cycle indexing with a suitable drive. The housing follows the standard MDD enclosure outline and uses common mounting hole patterns across the series.

For control accuracy, the motor uses resolver feedback, enabling fine angle resolution and sinusoidal commutation inside compatible Indramat drive amplifiers. Because the motor is supplied without a blocking brake, holding force on vertical axes must be provided by the drive or by external mechanical means. The output uses a plain shaft with standard end machining and no side-B extension. The motor is part of the MDD Synchronous Motors line, and the shaft has no seal, which helps reduce friction in clean, high-speed applications. This combination supports stable feedback processing and smooth motion on compact axes that require fast response rather than high holding torque.
