MDD071A-N-040-N2T-095GB2
The MDD071A-N-040-N2T-095GB2 belongs to the MDD Synchronous Motors series developed by Bosch Rexroth Indramat. It is a brushless servo motor intended for direct connection to compatible digital drive controllers, where it supplies precise rotary motion for positioning tables, handling axes, and light machining spindles. The unit integrates a blocking brake so driven loads can be held when power is off, and its standard housing and balancing allow installation in general-purpose industrial environments without extra mechanical preparation.
This motor can deliver a continuous standstill torque of 2.2 Nm, meaning that under constant current the shaft can sustain that torque without overheating. During movement it reaches a nominal speed of 4000 rpm, which sets the rated velocity for matching gear ratios and feed rates. When the brake is engaged, it clamps the shaft with 6.5 Nm of torque to help prevent back-driving on vertical or suspended loads. Position data are issued by an integrated multiturn absolute encoder, so shaft angle remains available across multiple revolutions without a homing cycle after power is restored. Feedback signals are transferred through digital servo feedback (DSF), allowing the controller to close the velocity and position loops with high resolution.
The flange centers on a 95 mm pilot, and the power and feedback plugs face Side B so cable routing can follow a fixed layout along the machine frame. The motor uses a sealed connector, which helps prevent dust ingress at the wiring joint, and the output end uses a plain shaft that mates directly with clamps, collets, or couplings. A shaft seal is present to help block lubricant migration into the motor interior, and the absence of a secondary shaft end on side B keeps the overall length compact for tight mounting spaces.
