Product Description:

Bosch Rexroth Indramat manufactures the MDD093A-N-040-N2M-110PA0, a synchronous AC servo unit in the MDD Synchronous Motors series. Designed for integration with digital drive controllers, this motor converts commanded current into precise rotary motion for positioning and velocity tasks across automated machinery that requires accurate starts, stops, and speed changes. The motor has size 093 and A length, which gives it the shortest stack in this frame.

The motor supplies a continuous standstill torque of 9.2 Nm, giving stable holding force without thermal overload. Its rated mechanical speed reaches 4000 rpm, enabling high-cycle axes when paired with matching inverters. Mounting interfaces are aligned by a centering diameter of 110 mm, and the motor uses standard balancing to limit vibration at top speed. The balancing grade permits direct coupling to precision gear stages without added vibration isolators. Power and feedback conductors exit on side A through a single connector, simplifying cabinet layout while maintaining shield continuity. A standard housing encloses the stator, and the motor supports high repeatability on indexing tables and pick-and-place gantries that run for long production periods.

Rotor position is transmitted to the drive through digital servo feedback, and the motor uses an integrated multi-turn absolute encoder for position tracking. For applications that secure the load mechanically, the unit is delivered without a blocking brake, reducing inertia and maintenance items. The output shaft has a keyway and is fitted with a shaft seal to limit lubricant leakage in IP-rated enclosures. Only one shaft end is present, leaving side B blank for close-coupled gearboxes. Combined with the encoder, this layout allows quick homing sequences and can eliminate external limit switches on many axes.
