Product Description:

The MDD090B-N-040-N2M-110PR0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed for use with digital drive controllers, the unit delivers closed-loop torque and speed control for indexing tables, material-handling axes, and packaging equipment in automated lines. Its operating profile suits machines that need repeatable motion, stable holding force, and consistent response during frequent starts and stops.

At standstill, the motor can develop a continuous torque of 7.2 Nm, enabling it to hold or slowly move loads without overheating. When driven to its rated velocity of 4000 min⁻¹, the rotor remains synchronized with inverter output to maintain smooth motion across the speed range. A centering diameter of 110 mm defines the pilot fit in the mounting surface and helps keep shaft alignment accurate. Power and feedback conductors exit on the right side, which can simplify cable routing on machine frames with mirrored axis layouts.

Frame designation 090 describes the stator diameter, while length code B provides a longer active stack for improved torque capability without changing the mounting footprint. The output shaft uses a keyway so torque can be transmitted through standard couplings without slip. Positional data is reported through Digital servo feedback, and the integrated multiturn encoder provides absolute position information after power cycles. The motor also uses a shaft seal, standard balancing, no blocking brake, and a connector interface for routine service access.
