Product Description:

The MDD025A-N-100-N2K-040GR1 is a miniature AC synchronous motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. When paired with digital drive controllers, it delivers rapid rotary motion to grippers, indexing tables, and other light-duty axes that require exact speed tracking. Its compact design suits installations where space is restricted and positional tolerances must remain tight. This makes it suitable for compact automation equipment that needs responsive motion without a large motor envelope.

The motor reaches a nominal speed of 10000 rpm and delivers a continuous standstill torque of 0.33 Nm. A factory-mounted holding brake rated at 1.0 Nm locks the shaft when power is removed, and the flange uses a 40 mm centering pilot for accurate mounting. Terminations exit to the right, and a single industrial connector allows plug-in wiring. Motion feedback is obtained through an integrated absolute encoder, while the short A length and size 025 frame help reduce axial footprint. The integrated feedback arrangement lets the drive monitor rotor position continuously during positioning tasks.

The motor has a plain shaft without a secondary side-B extension, and a shaft seal helps keep lubricants inside the machine enclosure. It uses a standard housing, and the resolver channel provides secondary position sensing and commutation signals through resolver feedback if the absolute encoder signal is unavailable. The auxiliary resolver path supports stable commutation during startup and low-speed operation, and the sealed shaft arrangement helps protect internal bearing areas from contamination. Because the shaft follows plain-bore geometry, coupling selection remains flexible, and the enclosure format matches common servo mounting dimensions used on light auxiliary axes.
