Product Description:

The MDD071B-N-040-N2T-095GB2 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts commanded current into controlled rotary motion for positioning and speed-regulated tasks in automated machinery. The standard housing supports direct mounting on compatible machine assemblies without special adaptation parts. An integrated blocking brake holds the load when power is removed, which is useful on vertical axes and indexing applications where unintended movement must be prevented.

A continuous stall torque of 4.4 Nm allows the motor to hold a steady load at standstill while remaining within permissible temperature limits. The nominal speed of 4000 rpm provides a high operating speed at rated voltage for responsive motion profiles. Power and feedback conductors exit on Side B through a sealed connector, so the installation must leave cable clearance on that face of the motor. A centering diameter of 95 mm helps align the flange accurately with gearboxes or mounting plates during assembly. Motion data is transmitted through Digital servo feedback (DSF), allowing the connected controller to maintain closed-loop position and velocity control.

The brake can provide up to 6.5 Nm of holding torque to resist motion while the axis is at rest. Position information is supplied by an integrated multiturn absolute encoder, so the motor retains position reference across power cycles without a homing move. The housing corresponds to Size 071, which helps the motor fit into compact machine spaces. The output uses a plain shaft with a shaft seal, allowing direct coupling while helping protect the shaft opening from contamination. A B-length stator and connector-based wiring are part of the standard configuration.
