Product Description:

Bosch Rexroth Indramat manufactures the MDD090B-N-030-N2M-130GR0, a member of the MDD Synchronous Motors series. This permanent-magnet servo unit is intended for closed-loop operation with compatible digital drive controllers, where it supplies controllable torque and speed for conveyor zones, material-handling gantries, automated tooling stations, and similar axis applications. Its design emphasizes repeatable positioning and fast response, making it suitable for short indexing moves, continuous duty, and stable speed regulation in medium-inertia loads across general industrial automation cells.

The mechanical interface begins with a centering shoulder of 130 mm, giving accurate registration to gearboxes or mounting flanges. Power and feedback leads exit on the right side, and a keyed connector allows rapid exchange without rewiring. At standstill, the motor can exert 7.2 Nm continuously, so thermal saturation will not occur during static holding or low-speed tasks. Position data is delivered by an integrated multi-turn absolute encoder, which reports shaft angle over multiple revolutions and eliminates the need for homing routines after power cycles. This combination supports accurate mounting, steady low-speed operation, and immediate position availability after power cycles in automated equipment.

Signal integrity between the motor and controller is maintained by digital servo feedback (DSF), enabling high-resolution velocity and torque loops. During process motion, the rotor reaches a nominal speed of 3000 rpm, aligning with inverter outputs commonly used in packaging and assembly lines. A plain shaft simplifies coupler selection, and a shaft seal helps block lubricants or dust from entering the bearing seat. Standard dynamic balancing limits vibration, and the B length code keeps the housing compact. Because the design omits a blocking brake, external mechanical locking devices must be used when power-off holding is required.
