Product Description:

The MDD090B-N-030-N2M-130PB0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it interfaces directly with matching amplifiers to supply closed-loop rotary motion in automated systems. By translating drive current into controlled torque, it serves as the primary mechanical element on axes that require accurate positioning and repeatable speed regulation across continuous duty cycles. The motor uses a standard housing that protects the internal windings from airborne contaminants.

Under continuous stall conditions, the motor produces 7.2 Nm, so the drive can hold static loads without overheating. During motion, it can reach a nominal speed of 3000 rpm, which suits common gear ratios and drive operation ranges. Power and feedback conductors exit on side B, keeping service access clear on the opposite face of the machine frame. A single industrial connector handles phase, ground, and sensor lines, which helps keep cable routing compact. Rotor position is returned to the controller through digital servo feedback (DSF), allowing high-resolution current loops without an additional external encoder.

A centering flange of 130 mm aligns the shaft concentrically with gearboxes, while an integrated multi-turn absolute encoder preserves position data through power cycles. Because the unit is supplied without a blocking brake, static holding torque must be generated electrically by the drive when power is removed. The shaft uses a keyway to transfer torque to couplings, and a factory-installed shaft seal limits oil ingress at the bearing journal. Standard dynamic balancing, motor length code B, and frame size 090 help keep vibration low in a compact footprint. The single-ended shaft end on the drive side supports installation in enclosed machine modules.
