Product Description:
The MDD071B-N-030-N2S-095PL1 is a synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed for digital drive controllers, it converts regulated drive current into precise rotary motion for positioning and speed-controlled tasks in automated machinery. Its compact 071 size and B-length frame fit medium-duty axes where continuous torque, stable feedback, and predictable response are important to coordinated multi-axis operation. Standard housing and balancing help the motor fit packaging lines, pick-and-place gantries, and light machine tools where installation space is limited and repeatable motion is required. This layout supports responsive starts, stops, and speed changes without requiring a large motor envelope.
At standstill, the rotor can deliver a continuous torque of 4.4 Nm, allowing the axis to hold load without exceeding thermal limits. During motion, the winding supports a nominal speed of 3000 rpm, letting the drive reach common production rates when paired with a compatible inverter. A factory-mounted blocking brake provides 3.0 Nm of static holding torque so vertical or suspended loads remain in place when power is removed. Command and feedback signals pass through a connector interface, and rotor position is reported by digital servo feedback for high-resolution closed-loop control. That feedback channel allows the controller to monitor rotor position continuously during acceleration, deceleration, and steady-state operation.
A centering diameter of 95 mm aligns the flange with the machine mounting surface for accurate installation. The single-ended output shaft is machined with a keyway so pulleys or couplings can be secured against slip during torque transfer. Power and feedback cables exit on the left side of the housing, which can simplify routing when the drive cabinet is positioned on the same side of the machine. The cable outlet orientation also reduces sharp bends when cables are routed toward a nearby cabinet wall. A factory-installed shaft seal helps keep coolant and dust away from the output-end bearing while retaining lubricant at the shaft.
