Product Description:

The MDD090B-N-030-N2M-130GL2 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for direct coupling to digital drive controllers where precise velocity and position regulation are required in automated production cells and machine tools. The motor supplies rotational energy to the mechanical axis, while its internal feedback circuit allows the controller to close a fast servo loop and maintain accuracy under changing loads. This arrangement supports responsive motion on axes that must start, stop, and reposition with repeatable control.

At standstill, the motor can deliver a continuous torque of 7.2 Nm, which is the steady load it can support without overheating. Under rated excitation, it reaches a nominal speed of 3000 rpm, matching common operating ranges for servo-driven machine axes. For short braking or indexing moves, the built-in blocking brake applies up to 11.0 Nm of holding torque to secure the load when power is removed. Alignment to adjoining machine frames is centered on a 130 mm pilot diameter, which helps maintain concentric mounting. Power and feedback leads exit on the left side, and the unit uses digital servo feedback (DSF) so the controller receives high-resolution position data during operation.

Position sensing is handled by an integrated multi-turn absolute encoder, which tracks multiple revolutions without a homing routine after startup. The output is a plain shaft, allowing direct coupling through clamping hubs or other suitable transmission elements. The motor uses a factory-installed connector for electrical interfacing, which simplifies wiring at the machine. Its size code is 090, placing it in a medium-frame format suited to applications that need moderate inertia and compact dimensions. Dynamic sealing is provided by a shaft lip that helps protect the bearing set from contaminants.
