MDD071B-N-040-N2T-095PR0
The Bosch Rexroth Indramat MDD071B-N-040-N2T-095PR0 belongs to the MDD Synchronous Motors series and is supplied as a motor for digital drive controllers used in positioning and velocity-controlled automation axes. It operates as the electromechanical actuator inside closed-loop drive systems, converting inverter current into mechanical rotation for tooling, handling, or transport tasks on factory lines. This arrangement allows the motor and controller to regulate axis motion precisely during starts, stops, and speed changes.
The motor delivers a continuous stall torque of 4.4 Nm, providing the sustained twisting force needed to hold loads during low-speed operation. Its rated speed of 4000 rpm is the maximum synchronized shaft velocity obtainable under nominal voltage and frequency. Position and speed data are returned through digital servo feedback (DSF), allowing real-time current and voltage modulation by the drive. An integrated multi-turn absolute encoder reports rotor angle over multiple revolutions without battery support, which eliminates homing cycles after power loss. The stator flange includes a 95 mm centering diameter to align the housing concentrically with machine frames, while the shaft uses a keyway so torque can be transmitted through standard keyed couplings.
Power and feedback conductors exit to the right through a connector interface, matching cabinets that route cables on that side. Standard balancing limits vibration, and the standard housing dissipates heat by natural convection. A shaft seal protects the front bearing against coolant or dust ingress, and the shaft end is single-sided to save space on the non-drive end. The motor has size code 071 and length code B. The unit is supplied without a blocking brake, so holding force must be provided by the drive or an external device when the axis is stopped.
