MDD071A-N-060-N2T-095PR2
The MDD071A-N-060-N2T-095PR2 synchronous servo motor is produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts controlled armature current into precise rotary motion for machine axes, transfer units, and handling modules in automated equipment. This model belongs to motor size 071 and length code A, giving it a compact envelope suited to high-speed positioning tasks where limited space, low rotor inertia, and fast response are important.
The motor reaches a nominal shaft speed of 6000 rpm, allowing rapid indexing when paired with compatible drive modules. Continuous torque at standstill is rated at 2.2 Nm, which is the torque the stator can generate without overheating when the rotor is locked. A centering diameter of 95 mm aligns the housing to gearboxes or mounting flanges with repeatable concentricity. Position and velocity signals are returned through Digital servo feedback (DSF), giving the drive controller absolute position information after initial referencing. Power and feedback leads exit on the right side, which simplifies wiring inside cabinets where multiple axes are aligned horizontally. The rotor is balanced to the standard grade.
For load-holding and emergency-stop functions, the motor is supplied with a blocking brake that delivers 6.5 Nm of static torque and engages automatically when power is removed. All electrical terminations are made through a single industrial connector, which simplifies cable attachment. The ground steel shaft has a keyway so pulleys or couplings can be fixed against slip, and it is protected by an internal shaft seal to limit lubricant ingress. Feedback of multi-turn position is provided by an integrated multiturn absolute encoder, eliminating the need for external homing routines. The motor has a standard housing and a single shaft end on side A for conventional coupling layouts.
