MDD071B-N-060-N2S-095PR2
Bosch Rexroth Indramat manufactured the MDD071B-N-060-N2S-095PR2 in the MDD Synchronous Motors series. This motor for digital drive controllers supplies rapid rotary motion for positioning and velocity loops in automated machinery such as packaging stations and pick-and-place gantries. By combining a permanent-magnet rotor with stator windings tuned for pulse-width-modulated inverters, the unit converts electrical commands into precise mechanical torque that can be modulated down to a standstill without losing servo stiffness.
The mechanical interface centers on a 95 mm pilot diameter that aligns the housing accurately with gearboxes or mounting flanges, while standard balancing limits residual vibration during high-speed operation. At standstill, the stator can deliver 4.4 Nm continuously, letting the axis resist process forces until motion resumes. A rated speed of 6000 rpm extends the usable velocity range for fast indexing tasks. Position information is returned through digital servo feedback, allowing the drive to close position and velocity loops with 32-bit resolution. Cabling exits on the right side, and the power and encoder leads are bundled in a single connector, which reduces assembly time. The model uses length code B, and the housing is standard for a compact mounting envelope.
A blocking brake is integrated and can hold up to 6.5 Nm, so vertical or suspended loads can remain stationary during emergency stops or power loss. The output shaft has a keyway and is built as a single-ended design without a second shaft on side B, which simplifies coupling alignment. A radial shaft seal is fitted to protect the bearings from coolant spray or dust. The motor uses size code 071, which corresponds to the frame diameter and winding cross-section used across the series. The housing and balancing are both standard rather than special-option versions.
