Product Description:

The MDD090C-N-040-N2L-110PR0 is a brushless synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it converts controlled three-phase power into precise rotary motion for indexing tables, packaging stations, and material-handling axes. Size designation 090 and length code C describe a medium-frame body that balances dynamic capability with a compact footprint. A standard housing allows installation without supplemental vibration dampers, and the unit has a single shaft end so mounting depth remains minimal inside crowded mechanical assemblies.

A centering diameter of 110 mm aligns the motor accurately to gearboxes or mounting plates, and standard balancing limits residual vibration at high speed. The electrical and feedback connections exit on the right side through a sealed connector, simplifying cable runs inside cabinets. Under continuous duty at standstill, the rotor can deliver 10.4 Nm of torque, allowing stable holding force against static loads. When commanded to rated frequency, the machine reaches a nominal speed of 4000 rpm, giving fast cycle times for dynamic positioning tasks. These values set the thermal and inertial demands for the matched drive amplifier.

The motor is supplied without a blocking brake, so external clamps or drive-generated torque must secure vertical axes during power loss. A fitted shaft seal protects the internal bearings from coolant spray and fine dust, helping preserve service life when the unit is mounted close to machining zones. Output torque is transferred through a keyway shaft profile, allowing rigid coupling to pulleys or pinions without additional interface hardware. Closed-loop control data is transmitted through digital servo feedback, enabling the drive controller to monitor rotor position with single-turn resolution and adjust phase currents in real time for accurate following performance.
