Product Description:

The MDD071A-N-040-N2T-095PA2 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it supplies closed-loop rotary motion to positioning axes, pick-and-place heads, and similar automation stages that need repeatable velocity and angle control. The motor is intended for applications that require accurate starts, stops, and rapid directional changes during cyclic machine operation. This operating profile suits packaging, assembly, and transfer equipment in which the axis must reach commanded positions repeatedly without drift. Its integrated blocking brake secures the load during power-off periods, while the standard housing and shaft seal allow installation inside general-purpose machinery without additional covers.

The motor develops a continuous standstill torque of 2.2 Nm, providing stable holding force when the shaft is energized but not rotating. Under rated electrical frequency, it reaches a nominal speed of 4000 rpm, giving fast dynamic response in short-stroke moves. For emergency or dwell conditions, the brake produces 6.5 Nm so the load remains fixed until motion is re-enabled. A centering diameter of 95 mm aligns the stator flange to the machine plate and helps maintain accurate mechanical fit. Standard balancing minimizes residual vibration at working speed, and the single-ended shaft omits a side B extension. The continuous torque rating supports stable motion at zero speed, while the higher brake torque is used for holding when electrical power is removed.

The frame corresponds to Motor Size 071, and the compact A-length permits mounting where axial space is limited. Power and feedback conductors exit on Side A through a sealed connector, simplifying cable routing in crowded cabinets and tight machine layouts. A keyway shaft type transmits torque to pulleys or couplings without slip. Position data come from the Integrated multiturn absolute encoder, and velocity loops are closed via Digital servo feedback (DSF) for precise synchronization with the drive controller. The encoder retains absolute position over multiple revolutions, and the DSF channel provides the drive with the feedback signals needed for accurate stopping and repeatable indexing.
