Product Description:

The MDD071B-N-040-N2T-095GA0 synchronous motor is manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for coupling to digital drive controllers, the unit converts commanded current into rotary motion for indexing tables, packaging stations, and other automated axes. Its synchronous design supports accurate speed and position control in applications that require repeatable starts, stops, and holding behavior during frequent cycle changes.

At the mechanical interface, the motor seats against a centering pilot of 95 mm, and its rotor is balanced to the standard grade, so additional field trimming is not required. Power and feedback leads exit on Side A through a sealed connector, simplifying cabinet routing while keeping the rear surface free for cooling air. A plain shaft with a standard shaft end mates to couplings or pulleys. Continuous torque at standstill is 4.4 Nm, allowing the motor to hold loads while motionless without overheating. When energized by the drive, the rotor can reach a nominal speed of 4000 rpm, matching fast pick-and-place axes. Position data is exchanged over digital servo feedback (DSF), enabling the controller to close tight loops with a single cable set. The motor uses a connector-based connection type, length code B, and a standard cast housing that supports natural convection.

In addition to the closed-loop feedback, the rotor angle is referenced by an integrated multiturn absolute encoder, so homing routines are unnecessary after power loss. The front bearing region is guarded by with a shaft seal, which helps restrict oil or dust ingress in installations near lubricated gear stages. The motor ships without a blocking brake, so holding torque must be supplied by the drive or an external clamp. The compact 071 frame and plain shaft design reduce inertia, while the standard length code B preserves thermal headroom for the rated torque. The connector interface supports direct cable attachment, and the standard housing finish resists common shop contaminants.
