Product Description:

The MDD025A-N-100-N2G-040MR0 is a compact AC synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed as a motor for digital drive controllers, it converts drive current into precise rotary motion for indexing tables, small pick-and-place axes, and other light-duty automation tasks. Its A-length housing and standard mechanical interfaces let the unit mount directly to gearheads or belt stages, while the high nominal speed supports rapid cycle times in tightly sequenced production lines. This layout also suits compact axes that need quick starts and stops without adding unnecessary bulk to the machine.

Its nominal shaft velocity reaches 10000 min⁻¹, allowing fast positioning when paired with suitable inverters. Continuous torque at standstill is rated at 0.33 Nm, so the motor can hold a small load without overheating during static clamping or fine assembly. The unit belongs to size code 025, a frame that keeps mass and rotor inertia low for responsive motion. A centering flange diameter of 40 mm aligns the motor concentrically to the driven element, which helps reduce runout during operation. For applications that incorporate external brakes or rely on drive torque alone, the motor is supplied without a blocking brake.

Signal integrity and connectivity are addressed through resolver feedback, which supplies analog rotor-angle data to the controller for closed-loop commutation across the full operating range. Power and feedback conductors exit on the right, simplifying cable routing when the motor is mounted on gantry crossbeams or side plates. A single industrial connector handles both phases and feedback cores, reducing enclosure penetrations and keeping the motor interface compact. The output shaft uses a keyway interface, giving a straightforward means of transmitting the motor’s torque to pulleys or couplings without relying on shrink-fit joints.
