Product Description:

The MDD090C-N-030-N2M-110GB2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. It is designed for use with digital motion controllers and converts regulated electrical energy into rotary mechanical output for positioning and speed-controlled tasks in automated machines. The motor uses length code C, which gives it a compact housing format for systems where the available mounting space is already set. This layout supports integration into established machine assemblies without changing the basic motor footprint.

At standstill, the motor can deliver 10.4 Nm of continuous torque without exceeding its thermal limits. This rating indicates the continuous torque available to hold a load at zero speed. During movement, it reaches a nominal speed of 3000 rpm, supporting common feed-axis and spindle duties without requiring mechanical gearing changes. A built-in holding brake adds 11.0 Nm of auxiliary torque for secure power-off parking. Position is tracked by an integrated multi-turn absolute encoder, and the signal is transmitted through Digital servo feedback (DSF), allowing closed-loop control with reduced wiring complexity. Factory balancing remains at a standard grade to support smooth running across the rated speed range.

Mechanical integration is aided by a 110 mm centering diameter that fits common motor mount pilot holes and helps maintain concentric alignment. Power and feedback conductors exit on Side B, which can simplify cable routing when the service side of the machine is kept to one direction. The output uses a Plain shaft, allowing clamp couplings to be installed without a key where low backlash is important. A shaft seal helps protect the internal bearings by limiting the entry of dust and splashed fluids while also reducing lubricant migration along the shaft.
