Product Description:

The MDD090C-N-040-N2L-110GR0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed for use with digital drive controllers, it converts current setpoints into controlled torque and speed for positioning tables, handling robots, and similar automation axes. Its electromagnetic design, feedback interface, and shaft geometry work together so the drive amplifier can execute high-speed motion profiles with repeatable accuracy. This layout supports applications that require stable response during frequent acceleration, deceleration, and positioning moves.

The motor sustains a continuous standstill torque of 10.4 Nm, giving it enough torque for static holding and low-speed operation without overheating. Under rated excitation, it reaches a nominal speed of 4000 rpm, which supports rapid indexing in automated equipment. Precise mounting is assisted by a centering diameter of 110 mm, which fits standardized pilot bores on gearboxes or machine frames. All power and feedback conductors exit on the right side through a keyed connector, helping keep cable routing clear of airflow paths. The rotor is balanced to the standard grade to reduce vibration, and the housing is supplied in the standard unenclosed version for cabinet-filtered cooling.

Position data is returned through Digital servo feedback, allowing the controller to synchronize multiple axes on a common bus. The motor has no blocking brake, so a separate holding device is required when power is off. It uses frame size 090 with length code C, which corresponds to the active lamination stack and overall body depth of this motor version. A Plain shaft with an integrated shaft seal supports direct coupling while helping limit lubricant migration, and the design omits a side-B shaft end to keep the overall motor length shorter.
