MDD071B-N-040-N2T-095PA0
Bosch Rexroth Indramat manufactures the MDD071B-N-040-N2T-095PA0 synchronous motor in the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts drive current into rotary motion that indexes, positions, or follows speed commands in automated machinery. The device suits pick-and-place heads, compact gantries, and feed axes where fast response, integrated feedback, and a small frame size support coordinated multi-axis motion. This makes it suitable for machines that require accurate starts, stops, and repeatable path control.
Its continuous torque at standstill reaches 4.4 Nm, giving the drive sufficient holding force to maintain load position without excess heating during closed-loop idle. Under rated excitation, the rotor can spin at a nominal 4000 rpm, which suits the speed range commonly used by compact spindles and linear modules. Mechanical alignment to gearboxes or machine mounts is set by the 95 mm centering diameter, which forms the pilot register on the flange. Real-time commutation is supported by digital servo feedback (DSF), which relays high-resolution position data to the controller. An integrated multi-turn absolute encoder tracks revolutions through power cycles, so the control system can retain position information after shutdown. This feedback arrangement supports stable control during acceleration, reversal, and low-speed holding.
For installations that rely on mechanical locking or drive torque instead of a brake, the motor is delivered without a blocking brake. A molded sealing ring provides a shaft seal, limiting lubricant escape and protecting the bearings from splash or dust when the unit is mounted on exposed axes. Power and feedback cables exit on side A, which helps keep cable runs consistent when several motors share a common panel. The output shaft uses a keyway, making it suitable for rigid connection to timing pulleys, gear wheels, or clamping hubs. With both cable connections on one side, the motor can also fit more neatly into closely spaced axis groups.
