Product Description:

The MDD093B-N-020-N2M-130GA2 belongs to the MDD Synchronous Motors series produced by Bosch Rexroth Indramat. As a motor for digital drive controllers, it converts command currents from the drive into controlled rotary motion for position-, speed-, and torque-controlled axes in automated machinery. Integrated multi-turn absolute feedback and digital servo feedback support closed-loop control without external encoders, while the built-in blocking brake secures the axis when power is removed. It is suited for machine axes that need consistent feedback-based motion and controlled holding at standstill.

The mechanical interface starts with a centering diameter of 130 mm, allowing rigid alignment in flange mounts. The centering fit also helps maintain concentric alignment between the motor and the mounting surface. Power and feedback conductors exit on side A through a plug-in connector, which helps keep cable routing organized. When energized and held stationary, the rotor delivers 14.5 Nm of continuous torque at rated stall current. Under dynamic operation, the winding supports a nominal speed of 2000 rpm. Digital servo feedback relays position data to the drive, and the multi-turn encoder preserves the absolute shaft position through power interruptions.

A blocking brake rated at 22 Nm clamps the shaft mechanically so vertical or suspended loads can remain fixed without drive current. The motor uses length code B and frame size 093, giving it a compact housing with moderate inertia for general servo axes. A plain shaft with a shaft seal is used on the drive end, and there is no shaft extension on side B. The housing uses the standard style and standard balancing. The shaft seal helps limit the entry of coolant spray and dust while protecting the bearing area during normal machine operation.
