Product Description:

The MDD071C-N-040-N2T-095PB2 is a synchronous motor developed by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. In automation cells, this motor couples with digital drive controllers to convert commanded current into precise shaft rotation for indexing tables, pick-and-place heads, or packaging axes. Its housing follows the standard mechanical envelope, and the shaft end is supplied in a standard configuration without an auxiliary shaft on side B, simplifying coupling to gearboxes or pulleys.

Under rated conditions, the motor delivers 6.6 Nm of continuous standstill torque, giving stable drive force for loads that must be held without motion. When energized to its synchronous operating point, it reaches a nominal speed of 4000 rpm, allowing fast cycle times in short-stroke axes. Position retention during power-off is provided by the integrated blocking brake, which clamps the shaft with 6.5 Nm of torque. Mechanical alignment in a machine frame is aided by a centering diameter of 95 mm, and all electrical connections exit on Side B, enabling cable routing away from the working zone. Standard rotor balancing limits vibration, the connector-based terminals simplify installation, and a shaft seal helps prevent lubricant from entering the motor interior.

Digital servo feedback transmits high-resolution rotor position, while the built-in multiturn absolute encoder stores shaft angle over multiple revolutions for homing-free startups. The frame is classified as size 071, and the length code C provides additional stack height for higher magnetic flux without enlarging the centering interface. A hardened shaft with a keyway accommodates common keyed couplings, and the shaft seal supports use in oil-mist or coolant-rich environments. The housing remains in the standard configuration, and the motor is compatible with drive controllers that accept DSF signals.
