Product Description:

The MDD071A-N-040-N2S-095PB2 is a synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It serves as the rotary actuator in digital drive systems, translating current-regulated commands from the controller into precise shaft movement for machine tools, packaging lines, and assembly cells. A standard housing and balanced rotor let the unit mount directly onto mechanical frames, while the integrated shaft seal protects the internal bearings in environments that may contain cutting fluids or light splashing. This arrangement supports controlled starts, stops, and repeatable positioning on automated axes.

The motor’s centering flange is machined to 95 mm, providing a repeatable reference surface for aligning the stator with gearbox or load adapters. Power and feedback cables exit on Side B through a single connector, which simplifies cable routing and keeps the installation compact. At stall, the electromagnetic system delivers 2.2 Nm of continuous torque without exceeding thermal limits. A blocking brake mounted on the non-drive end supplements this by holding the axis with up to 6.5 Nm when power is removed. Standard dynamic balancing minimizes residual vibration across the working speed range and helps reduce stress on connected couplings.

During operation, the rotor reaches 4000 rpm, a nominal speed suited to medium-inertia loads common in pick-and-place modules. Position data is returned through digital servo feedback, allowing the controller to correct motion within a single control cycle. Mechanical coupling takes place through a shaft end with a keyway, and the absence of a second shaft on side B preserves a compact overall length that matches the A-coded build. The frame designation 071 identifies the stator diameter, which helps match the motor to compatible mounting hardware and cable accessories.
