Product Description:

The MDD090A-N-030-N2L-130PR2 is a permanent-magnet synchronous servo motor manufactured by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. Intended for digital drive controllers, the unit converts controlled current from the drive into mechanical rotation for positioning, indexing, or speed-regulated production tasks. Its compact A-length frame and standard housing let it fit inside machines where space is limited while still supplying the dynamic response required in automated packaging lines, pick-and-place equipment, and general material-handling axes. This design is suited to applications that require accurate positioning and repeatable speed control under changing loads.

A centering diameter of 130 mm forms the pilot fit between the motor flange and the machine frame and helps maintain coaxial alignment. Power and feedback leads exit on the right side, simplifying cable runs in cabinets built around lateral routing. At standstill, the electromagnetic design delivers a continuous torque of 3.7 Nm, allowing small loads to be held without overheating. During dynamic stops, the integrated blocking brake supplies 11.0 Nm of holding torque to secure vertical or suspended axes when power is removed. Under rated excitation, the rotor reaches a nominal speed of 3000 rpm, enabling direct coupling to gearboxes or belt drives without overspeed.

Field wiring is completed through a sealed connector, so the motor can be connected without opening the housing. Torque is transmitted through a shaft with a keyway, giving positive engagement with couplings, and the shaft seal helps keep lubricant and contaminants separate. The motor uses frame size 090, and its digital servo feedback (DSF) returns rotor position for current control and electronic commutation. This feedback arrangement supports stable commutation and accurate motion control across the operating range.
