Product Description:

The MDD071A-N-040-N2S-095GA1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it delivers commanded torque and speed in closed-loop industrial automation axes where compact electromechanical units replace hydraulic or pneumatic actuators. In automated equipment, it can be used on positioning, feeding, and handling axes that require repeatable rotary motion during frequent start-stop cycles. Mechanical alignment to gearboxes or mounting flanges is supported by a centering diameter of 95 mm, which helps position the motor accurately during installation.

At its rated operating point, the motor reaches a nominal speed of 4000 rpm, allowing high-cycle positioning on packaging, printing, and assembly lines. A continuous standstill torque of 2.2 Nm allows the motor to hold a steady load without overheating, while a blocking brake provides up to 3.0 Nm to secure the shaft when power is removed. The built-in digital servo feedback (DSF) transducer returns rotor position to the drive for precise current vector control. The rotor uses standard dynamic balancing to reduce vibration throughout the speed range, and the motor length code A indicates the shortest package within the 071 frame.

Wiring exits the stator housing on Side A through a keyed industrial connector, keeping the power and feedback leads oriented toward the cabinet. The motor uses a plain shaft, making it suitable for clamp or shrink-fit couplings, and a protective shaft seal is included to help resist lubricant ingress when the unit is mounted in machinery that uses oil lubrication. Because the shaft is non-keyed, torque transfer depends on the selected hub or clamping element rather than a keyed connection. The standard coated housing supports general plant environments, and the 071 frame size helps the motor fit into tight machine layouts without additional brackets.
