Product Description:

The MDD090C-N-030-N2M-130GA2 is a synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. The model is intended for use with digital drive controllers to supply closed-loop torque and speed in automated handling, machining, and assembly stations where accurate positioning and repeatable speed control are required. By combining permanent-magnet excitation with electronic feedback, it converts electrical power into precise mechanical rotation suited to tightly regulated industrial axes. Its mechanical construction follows the series coding, placing it in the 090 frame family and the C length group for standardized mounting interfaces.

At standstill, the motor can deliver a continuous torque of 10.4 Nm, allowing static loads to be held without thermal derating. During motion profiles, it reaches a nominal speed of 3000 rpm, so the connected inverter must generate the corresponding electrical frequency. The built-in blocking brake supplies 11.0 Nm of retention torque when engaged, preventing axis drift after power removal or an emergency stop. Rotor position is sent to the controller through digital servo feedback (DSF), providing high-resolution incremental data for tight speed loops. Absolute position over multiple revolutions is stored by the integrated multiturn absolute encoder, eliminating separate homing sequences at each power-up.

Mechanical alignment is facilitated by a centering diameter of 130 mm, so the motor seats accurately in machine frames. Power and feedback wiring exit on Side A, keeping the connectors accessible while maintaining enclosure depth in compact installations. Torque is transmitted through a plain shaft chosen for smooth coupling engagement, and contamination is resisted by a shaft seal that helps protect the bearing cavity. Standard balancing and the housing finish help reduce vibration, and the C length code supports moderate inertia demands in mid-speed applications.
