Product Description:
The MDD090C-N-040-N2M-130GB1 is a synchronous servo motor built by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it provides velocity and position control to automated axes that rely on closed-loop regulation. In typical automation systems, it is suited for feed axes, transfer units, and positioning tables that require repeatable motion and stable feedback response. The unit uses the 090 frame size, carries the C length code, and comes with standard dynamic balancing. A standard housing encloses the stator windings and rotor, and the motor remains compatible with Indramat drive modules.
The motor reaches a nominal speed of 4000 rpm, allowing direct coupling to gearless loads that need high shaft velocity with minimal torsional ripple. A continuous standstill torque of 10.4 Nm can be produced indefinitely when proper cooling is maintained, giving enough holding force for indexing tables or vertical slides. Mechanical centering is aided by a 130 mm pilot diameter that fixes the flange against the mounting surface. Power, brake, and feedback leads exit from the rear because the connection ports are on side B and use a single industrial connector interface, which helps keep cable routing orderly in compact machines. Position data are transmitted through digital servo feedback, enabling the controller to execute high-resolution velocity loops.
The motor also includes several mechanical and safety features. The integrated blocking brake develops 6.5 Nm of static torque to hold a suspended axis when power is removed. Rotor angle is reported by an integrated multi-turn absolute encoder, so homing routines are unnecessary after shutdowns. A plain shaft is supplied and is protected by a shaft seal that limits grease or coolant ingress at the bearing seat. The motor has only one shaft end, so couplings can be mounted only on the drive end. The rear side remains free of a second shaft extension, leaving more room for the connector area.
