Product Description:

Bosch Rexroth Indramat manufactures the MDD090C-N-040-N2L-130PA1 in its MDD Synchronous Motors series. Classified as a motor for digital drive controllers, the unit converts commanded current into tightly regulated torque and speed. This allows automated conveyors, pick-and-place modules, and other servo axes to follow precise motion profiles in multi-axis CNC and PLC-based systems. It is suited to coordinated motion tasks where the controller must maintain stable low-speed rotation and accurate stop points from cycle to cycle.

The motor uses a centering shoulder with a 130 mm centering diameter for flange mounting to gearboxes or machine frames. A continuous standstill torque of 10.4 Nm lets the axis hold static loads without overheating, while a nominal operating speed of 4000 rpm supports rapid positioning cycles. The integrated blocking brake supplies 6.5 Nm of holding torque so vertical or overhung loads remain secure when power is removed. Power, feedback, and brake conductors exit on the Side A face through a molded connector, which helps cable routing in tight enclosures. A shaft seal is fitted around the keyed output shaft to help limit lubricant migration and the entry of particulates.

Digital feedback is provided by the DSF encoder, allowing the drive controller to close position and velocity loops with a single-turn absolute signal. The motor uses frame size 090 and the C length code, giving it the inertia and thermal mass suited to medium-duty feed axes without increasing the machine footprint unnecessarily. A keyway shaft end accepts standard couplings, and there is no second shaft extension on side B. The housing remains standard so it can fit existing mounting brackets in established machine layouts. This cable arrangement works with Rexroth hybrid cabling and keeps the motor compatible with common drive-side cable layouts.
