Product Description:

The MDD093D-N-020-N2M-130GB0 is a synchronous servo motor built by Bosch Rexroth Indramat and supplied in the MDD Synchronous Motors series. Designed for digital drive controllers, it converts commanded currents into precise rotary motion for positioning axes in industrial automation. The compact housing, universal flange pattern, and connectorized terminations support straightforward installation, while the embedded feedback hardware keeps the rotor locked in phase with the drive. It is suited for closed-loop motion tasks where the controller must coordinate acceleration, deceleration, and stable torque output across several linked axes.

Mechanical alignment is set by a centering pilot of 130 mm, which helps locate the motor on the machine plate and control radial runout. Rotor dynamics follow a standard balancing grade, so vibration remains within ISO limits at the 2000 rpm nominal speed. That operating point suits machinery that needs steady mid-range velocity without sacrificing servo response. When the stator is energized, the unit can hold a load with 24.0 Nm of continuous torque at standstill, which is useful on axes that must resist motion at zero speed. Position feedback is produced by an integrated multi-turn absolute encoder, and its memory lets the drive recognize shaft position after power loss. The encoder signals are transmitted through digital servo feedback, allowing high-resolution commutation without analog converters.

The power and feedback plugs are mounted on Side B, which helps route cables toward the rear in tight enclosures. The motor uses length code D, indicating the deepest stator variant within the 093 frame and contributing to higher torque density. The output end has a plain shaft with a shaft seal, which helps keep oil or coolant out of the bearing chamber during washdown cycles. The motor is supplied without a blocking brake, so holding force must be provided by the drive or an external device when the axis is stopped. Leaving out the brake also removes the need for separate brake release wiring inside the motor circuit.
