Product Description:

The MDD093D-N-040-N2M-110GB2 is a synchronous AC servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts commanded current into precise mechanical motion and supplies closed-loop torque and velocity to automated axes in packaging cells, handling modules, and general machine-tool assemblies. Its synchronous design supports repeatable positioning and stable speed control in applications that require accurate axis movement over changing load conditions.

The motor has mechanical and electrical interface parameters that support predictable installation. A continuous standstill torque of 24.0 Nm allows the motor to hold loads without overheating when the rotor is locked. During dynamic operation, it can reach a nominal rotational speed of 4000 rpm, which supports fast positioning cycles. Alignment to the machine frame is assisted by a centering diameter of 110 mm, which seats the stator housing concentrically inside a matching pilot bore. Power and feedback conductors exit on Side B, and the unit uses a sealed industrial connector for a direct external connection. Rotor position is reported through an integrated multi-turn absolute encoder, allowing the drive to recover exact shaft angle after power loss without a homing routine.

Additional features support load holding and shaft sealing. A holding brake rated at 22 Nm clamps the shaft when controller current is removed, helping prevent vertical loads from drifting at rest. The output uses a plain shaft, so couplings can be mounted directly on the journal without keyways that concentrate stress. Signal transmission to the drive uses digital servo feedback (DSF), which carries high-resolution position data and diagnostic information over a differential line. Standard rotor balancing helps limit vibration during high-speed operation, and a factory-installed shaft seal helps keep coolant splash away from the front bearing area.
