Product Description:

The MDD071A-N-060-N2S-095GA1 servo unit is manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts electrical commands into precise rotary motion for pick-and-place stations, packaging lines, and other industrial automation duties where high speed and repeatable positioning are required. Its compact housing and integrated feedback capability let it connect directly to modular drive platforms. In these systems, the motor serves as the rotary output element while the connected controller manages speed and position in closed-loop operation. This layout suits machine axes that need fast starts, accurate stops, and stable cycle-to-cycle motion.

The rotor is balanced to standard grade to minimize vibration at operating speed. Under rated excitation, the motor reaches a nominal velocity of 6000 rpm, supporting fast indexing on lightweight axes. At zero speed, it can supply a continuous standstill torque of 2.2 Nm. An internally mounted blocking brake produces 3.0 Nm of static torque so vertical loads stay fixed when power is removed. Position and velocity data are delivered through digital servo feedback (DSF), allowing the controller to process fine increments without an external encoder. This feedback arrangement supports closed-loop speed control and accurate positioning during rapid reversals. All power, brake, and feedback conductors exit on Side A, which can simplify cable routing when the motor is installed in tight machine frames.

A centering diameter of 95 mm aligns the frame precisely against gearbox flanges and mounting faces. The short A housing length also helps when installation space is limited and adjacent components are closely packed. The plain shaft is furnished with a shaft seal that helps limit coolant or lubricant ingress when the coupling area is properly enclosed. Because the design omits a shaft on Side B, the rear end stays compact and leaves less overhung mass at the non-drive side. Frame size 071 places the motor in a compact class suited to smaller servo axes where responsive motion and limited mounting space are both important.
