Product Description:

The MDD090C-N-030-N2M-110GL1 is a synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Intended for digital drive controllers in industrial automation cells, it converts regulated three-phase power into controlled shaft torque. This allows conveyor sections, gantry axes, and assembly robots to maintain repeatable speed and position profiles during closed-loop motion control. It is suited for axes that must accelerate, hold position, and reverse direction with consistent response.

It delivers a continuous standstill torque of 10.4 Nm, which is the load the motor can hold or slowly accelerate without overheating while the rotor is stationary. During motion, the rotor reaches a nominal speed of 3000 rpm, matching electrical characteristics commonly used with inverter-driven systems. A centering diameter of 110 mm aligns the motor flange with gearboxes or machine plates for concentric assembly, and standard dynamic balancing helps limit vibration at the mounting interface. The output uses a plain shaft for clamp or shrink-fit couplings, while an integrated multi-turn absolute encoder provides digital servo feedback to the controller for accurate position tracking after power cycles. The connection direction is left, so the power and feedback conductors exit on the left side.

Its blocking brake generates 6.5 Nm of static torque, allowing vertical axes to remain fixed when the drive is disabled. A connector interface simplifies the connection of brake, power, and encoder wiring and keeps cable routing straightforward at the motor. The motor uses frame size 090 with length code C, giving it a mid-range body size that balances inertia and continuous output for general machine axes. A fitted shaft seal helps protect the internal bearings from coolant spray or fine dust, and the standard housing supports installation without an added enclosure in typical industrial settings where the motor is mounted directly on the machine frame.
