Product Description:

The MDD071C-N-040-N2L-095PA2 is a synchronous servo motor designed by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. It is supplied for use with digital drive controllers, allowing precise electrical commutation from compatible Indramat positioning drives. In automated equipment, the motor converts drive current into rotary motion so tool changers, pick-and-place heads, and feed screws can maintain repeatable travel profiles under feedback control. Its compact 071 frame size suits medium-power axes that need both dynamic response and a small installation envelope.

The motor has a nominal speed of 4000 rpm, enabling mid-range linear velocities when it is coupled to belt or ball-screw transmissions. At standstill, the electromagnetic system can deliver continuous torque of 6.6 Nm, so static holding loads can be supported without overheating. An integrated blocking brake engages automatically and provides 6.5 Nm of holding torque during power loss, which is useful on vertical or suspended loads. Torque is transmitted through a keyway shaft end, and concentric alignment with the mating machine plate is aided by the 95 mm centering diameter. Standard dynamic balancing helps reduce vibration during high-speed operation.

Power and feedback conductors exit on side A through a sealed connector, which helps simplify cabinet routing and maintain EMC separation. Position and velocity data are produced by the built-in digital servo feedback encoder, permitting direct integration with the companion drive. A shaft seal helps limit contaminant ingress, and the motor uses a standard housing for its basic mechanical configuration. The C length code extends the active stack without increasing the cross-section, which allows higher torque density than shorter versions while retaining a single-ended shaft.
