Product Description:

The MDD071B-N-040-N2S-095GA2 is a synchronous servo motor built by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. It is intended for use with digital drive controllers and converts commanded electrical vectors from an Indramat drive into mechanical rotation for positioning and acceleration in automated cells, packaging stations, and material-handling lines. Its compact frame, matched electrical feedback, and integrated brake let it support precise axis motion while keeping installation space low. It is suited for machines that need accurate stopping and repeatable motion from a compact servo package.

At standstill, the rotor can deliver 4.4 Nm of continuous torque, which helps hold loads or overcome static friction without excessive heat buildup during short pauses. During dynamic operation, the allowable shaft speed reaches 4000 rpm, giving the motor a moderate operating range for mid-size pick-and-place or spindle duties. Mechanical integration is simplified by a centering pilot of 95 mm, which helps align the flange to the machine frame and keep runout low. Power and feedback conductors exit on Side A through a keyed connector interface, which keeps the electrical connection compact and direct.

The integrated blocking brake supplies 6.5 Nm of static holding torque, so vertical axes can remain fixed when power is removed. Position feedback is generated by digital servo feedback (DSF), allowing closed-loop commutation and motion control without a separate external encoder for basic operation. The motor uses frame size 071 with the B length build, and it has a plain shaft without a side-B extension for direct coupling to pulleys or gearboxes. A shaft seal helps protect the bearing area from contamination at the output end, and standard balancing supports smooth rotation during operation.
