Product Description:

The MDD090B-N-030-N2M-130PA2 is a permanent-magnet synchronous unit produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It serves as a drive element for digital controllers, converting electrical energy into controlled rotary motion for indexing tables, handling modules, and other automated axes. By integrating rotor magnets and stator windings in a compact housing, the motor supports rapid torque changes and precise positioning cycles required in modern production cells without using mechanical gear stages that add backlash or increase maintenance.

A centering flange diameter of 130 mm forms the mounting interface and promotes accurate concentric alignment between the motor and the machine frame. Electrical and feedback cables exit on Side A, and a single multi-pin connector reduces wiring complexity while preserving shield continuity. Under rated thermal conditions, the motor delivers 7.2 Nm of continuous standstill torque, so it can hold static loads without overheating the winding. During motion, the rotor tracks command velocity up to 3000 rpm, matching drive electronics that supply 300 Hz electrical frequency. Standard dynamic balancing minimizes residual vibration at these speeds to protect bearings and attached mechanics.

The integrated blocking brake supplies 11.0 Nm of holding torque to secure vertical or suspended loads when power is removed. Position data is transmitted through digital servo feedback, and the internal multi-turn absolute encoder eliminates external homing routines while reporting shaft turns to the controller. Power is delivered through a shaft machined with a keyway, and contamination ingress is limited by a design that ships with a shaft seal. The motor uses length code B with size 090 laminations, and it has a single-ended shaft so no extension is present on side B.
