Product Description:

The MDD071C-N-040-N2S-095PA1 is a synchronous servo motor from Bosch Rexroth Indramat in the MDD Synchronous Motors series. Built for digital drive controllers, it supplies precise rotary motion to axes in machine tools, printing presses, and handling equipment. This model connects quickly, fits compact spaces, and supports closed-loop positioning in high-cycle automation. Its operating role is to convert commanded current into controlled shaft motion so the drive can maintain accurate speed and position during repeated machine cycles.

The motor has a nominal speed of 4000 rpm, which indicates the rotor’s steady operating speed under rated voltage and load. At standstill, it can deliver 6.6 Nm of continuous torque, making it suitable for holding or slowly indexing loads without overheating. For short periods, the integrated blocking brake secures the shaft with 3.0 Nm of static torque to help prevent back-driving after the amplifier is disabled. Mechanical mounting uses a 95 mm centering diameter that aligns the flange with the machine frame. Power and encoder conductors exit on Side A through a sealed connector, which can simplify cable routing in compact enclosures. The rotor uses standard balancing, and the motor has a standard housing configuration for typical MDD installations.

Signal transmission is handled by digital servo feedback, which sends position data to the drive so the control loop can respond quickly to load changes during motion. The motor uses size 071 and a Motor Length Code C housing, giving it a mid-length body that balances inertia and torque density in compact machine layouts. A factory-installed shaft seal helps keep coolant mist and dust out of the bearing cavity during operation. The shaft has a machined keyway on the drive side only, while side B has no shaft extension. This layout supports guarded couplings and keeps the non-drive end mechanically simple.
