Product Description:

The MDD093D-N-040-N2M-130GB0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Intended for direct coupling to digital drive controllers, it supplies closed-loop mechanical power to numerically controlled machines and automated handling modules. The D-length stator and 093 frame place the motor in a mid-torque class that balances dynamic response with thermal capacity. This layout suits feed axes that must accelerate rapidly, stop accurately, and remain stable during continuous operation.

The centering pilot on the flange measures 130 mm, allowing rigid seating against gearboxes or spindle mounts. At standstill, the motor can provide 24.0 Nm of continuous torque, so the connected drive must supply enough current to maintain that load without derating. Under rated electrical frequency, the rotor reaches 4000 rpm, giving linear axes high traverse speed while maintaining smooth motion. Power and feedback leads exit on side B, which helps keep cables away from the working end of the machine. A single multipole connector carries the phase conductors, encoder lines, and protective earth, reducing separate wiring runs and simplifying routing inside the equipment.

Position and rotation data are delivered by an integrated multiturn absolute encoder, which eliminates homing routines and retains position information through power interruptions. Feedback is provided as digital servo feedback (DSF), allowing compatible drives to run precise current, speed, and position control loops. The motor is supplied without a blocking brake, so vertical or suspended loads may require an external holding device when power is removed. A plain shaft with a factory-installed shaft seal supports direct coupling and helps limit contaminant entry in applications exposed to coolant splash or light washdown conditions.
