Product Description:

The MDD090C-N-020-N2L-130GB2 is a brushless synchronous motor engineered by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where commanded current is converted into precise rotary motion for indexing tables, handling modules, and other automated axes. An internal permanent-magnet rotor and laminated stator support repeatable positioning on medium-inertia loads in assembly cells, packaging lines, and general material-processing equipment. This arrangement gives the motor stable response during start-up, speed changes, and position holding in closed-loop motion systems. The motor is suited to applications that require repeated indexing, controlled acceleration, and reliable settling after frequent start-stop cycles.

The servo reaches a nominal shaft speed of 2000 rpm, allowing the axis to follow moderately fast machine cycles. At standstill, the electromagnetic system develops 10.4 Nm of continuous torque, so the motor can support holding duty and load pickup without exceeding normal thermal limits. For brief stopping or retention, the integrated blocking brake provides up to 11.0 Nm of mechanical torque. Closed-loop regulation relies on digital servo feedback, which returns position data to the controller for accurate speed and position correction. Power and signal leads are arranged on Side B, helping keep the cable exit organized at the rear of the motor housing.

The flange uses a centering diameter of 130 mm to support accurate alignment with machine plates or gearboxes. The motor has size 090 and length code C, which place it in a compact medium-frame format with enough surface area for heat dissipation during normal operation. Torque is transmitted through a plain shaft, making it suitable for keyless clamping elements and other friction-based couplings. A fitted shaft seal helps protect internal bearing areas from dust and fluid ingress, and the housing uses standard dynamic balancing to limit vibration during rotation. Its flange and shaft arrangement also support direct coupling where alignment accuracy affects repeatability and bearing life. The design omits a second shaft extension on side B, which keeps the rear end dedicated to the electrical connection layout.
