Product Description:

The MDD090B-N-040-N2M-130GA0 is a servo motor built by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. Designed for integration with digital drive controllers, the unit converts electrical input into controlled rotary motion for positioning and speed-control tasks in automated machinery. Its mechanical outline, feedback hardware, and electrical interface allow direct coupling to compatible Rexroth drive modules used in packaging, printing, and material-handling axes. This type of motor is suited to closed-loop applications where the controller must maintain accurate motion through frequent starts, stops, and load changes. It can be used on feed axes, transfer mechanisms, and indexing stations that depend on stable servo response throughout repeated production cycles.

The motor seats on a centering diameter of 130 mm, aligning with gearboxes or mounting flanges. At standstill it delivers 7.2 Nm of continuous torque for load holding without extra cooling. During operation, the rotor reaches a nominal speed of 4000 rpm. All power and feedback lines exit on Side A, which helps keep cable routing consistent when several axes share one panel. A circular Connector provides the electrical interface and supports straightforward cable removal. The fixed cable exit orientation also helps reduce crossing between motor and feedback leads in compact enclosures. The unit is supplied without a blocking brake, so static loads must be secured by the drive or an external clamp. A shaft seal protects the internal bearings against coolant splash and dust ingress.

Feedback is handled through an integrated multi-turn absolute encoder that communicates over Digital servo feedback (DSF), allowing high-resolution position data to reach the drive. Absolute position information is retained across multiple shaft revolutions, which supports axis recovery after normal power cycling. Within the MDD frame, the unit is classified as size 090, and its length designation B gives a compact motor body with mid-range torque capability. Dynamic balance is standard, which supports smooth rotation in typical machine assemblies. The plain shaft end supports use with clamping hubs and similar shaft connections, and the integrated shaft seal helps protect internal components when matched with sealed connectors. The housing follows the standard MDD profile, so it fits machine layouts built around this motor family.
