Product Description:

The MDD090C-N-040-N2L-110PR2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat and supplied within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts drive output into controlled rotary motion for positioning and velocity tasks in automated machinery. The unit has a single-ended shaft and an integral holding brake, so machines can index loads precisely and keep the axis in place when power is removed.

At standstill, the motor delivers a continuous torque of 10.4 Nm, providing constant force for applications that require static holding or low-speed feed motion without overheating. When power is removed, the integrated brake supplies a holding torque of 11.0 Nm so suspended axes remain fixed. During operation, the rotor can reach a nominal speed of 4000 rpm, which suits mid-range spindle and conveyor duties. Position feedback is generated through digital servo feedback, allowing the controller to close high-gain speed and position loops. Mechanical output is transmitted through a shaft with a keyway, which provides positive torque transfer to pulleys or couplings.

Mechanical integration is supported by a centering flange diameter of 110 mm, which aligns the motor accurately to the machine interface, while the standard balancing grade helps limit vibration during operation. Power and feedback cabling exit on the right side through a compact connector, which leaves the opposite face more open for nearby components. A shaft seal is fitted to help block dust or fluids from entering the front bearing area. The standard housing supports installation in enclosures that use forced air or natural convection for heat removal. The motor uses frame size 090 and length code C, giving a consistent mounting pattern within the series.
