Product Description:

The MDD093A-N-040-N2M-110GA0 is a brushless AC servo motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Intended for use with compatible digital drive controllers, the unit supplies closed-loop rotary motion for pick-and-place arms, gantry axes, and other automated stages that require fast speed regulation and repeatable positioning. Its 093 frame size and A-length housing permit compact installation, while the standard housing finish suits general-purpose machine environments. The brushless design supports stable torque response during repeated motion cycles and avoids the wear associated with mechanical commutation.

Performance is anchored by a nominal shaft velocity of 4000 rpm, allowing high cycle rates when paired with matching inverters. At standstill, it sustains 9.2 Nm of continuous torque, which indicates the torque available at zero speed during continuous operation. Mounting accuracy is supported by a 110 mm centering diameter, so the flange aligns concentrically with gearboxes and coupling hubs. Power and feedback cabling exit on Side A, simplifying wiring in cabinets where other equipment occupies the opposite face. A plain shaft transmits torque through press-fit couplings or clamp sleeves, which helps avoid the stress concentrations that can occur with keyed connections.

Signal integrity is maintained through digital servo feedback (DSF) that relays real-time rotor angle to the drive, and the integrated multi-turn absolute encoder retains position information through power interruptions. This feedback arrangement allows the connected drive to monitor shaft position continuously during acceleration, deceleration, and dwell periods. The motor is supplied without a blocking brake, so vertical load holding must be provided by drive torque or an external clamp when the axis is idle. A factory-installed shaft seal limits dust and fluid ingress at the output end, and the standard dynamic balancing grade supports smooth rotation in packaging, electronics assembly, and light machining cells.
