MDD071A-N-030-N2L-095PB0
The MDD071A-N-030-N2L-095PB0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is used with digital drive controllers to provide closed-loop torque and speed control for automated axes. Its compact dimensions come from motor size 071 and length code A, while the standard housing and balancing allow direct machine integration without additional adaptation. Permanent-magnet excitation allows quick acceleration, making the unit suitable for positioning tables, feeders, and light machining spindles in mixed-duty production cells.
The centering pilot measures 95 mm, providing an accurate location surface for flange mounting and helping maintain coaxial alignment with the driven load. A nominal speed of 3000 rpm matches common inverter operation and sets the base operating point for velocity-regulated tasks. At standstill, the motor can deliver 2.2 Nm of continuous torque, so it can hold modest static loads without overheating. Power and feedback connections exit on Side B, keeping cables away from the shaft end, and the detachable connector interface simplifies cable installation. The motor has a standard shaft end on the drive side only, and the housing has a standard finish that resists common shop contaminants.
A shaft seal is fitted to protect the bearing set from splash oil or dust ingress, and torque is transmitted through a keyway that fits conventional keyed hubs. The motor is supplied without a blocking brake, so external clamping or drive torque must secure vertical or suspended loads when power is removed. Position and velocity are reported through digital servo feedback (DSF), allowing high-resolution control loops in Rexroth drive amplifiers. Standard dynamic balancing helps reduce vibration during continuous duty, and the single-ended shaft arrangement leaves the rear frame open for cable routing and access.
