MDD071A-N-030-N2S-095PL1
The MDD071A-N-030-N2S-095PL1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it converts regulated current into rotary motion for packaging lines, material-handling axes, and other automated equipment. A spring-applied blocking brake is integrated to hold the shaft when the controller is disabled, which helps prevent load drift during planned stops or power loss. It is intended for servo axes that require repeatable motion and fast response to changing command values. This arrangement supports controlled axis holding without requiring a separate external brake assembly.
Its centering pilot diameter is 95 mm, which helps the flange seat accurately against gearheads or bearing plates. Power and feedback conductors exit on the left side through a keyed connector, allowing the cable set to be attached without disturbing fixed routing. The electromagnetic stack sustains 2.2 Nm of continuous torque at standstill, and the mechanical brake withstands up to 3.0 Nm for load holding. Closed-loop position data are generated by digital servo feedback (DSF), so the drive can maintain stable speed regulation and accurate positioning. Standard rotor balancing helps reduce vibration during repeated acceleration and deceleration cycles.
The unit carries length code A, which is the most compact build in the 071 frame and helps where axial space is limited. When supplied at nominal voltage, it delivers a rated speed of 3000 rpm, making it suitable for direct couplings and 1:1 belt stages that require steady medium-speed operation. A standard housing encloses the stator, and a shaft seal helps keep dust and coolant away from the bearing cavity. The single output shaft includes a keyway for positive torque transmission, while the B-side remains closed because there is no second shaft extension. The enclosed non-drive end also keeps the rear of the motor simple for installation inside compact machine layouts.
