MDD071A-N-040-N2S-095PR2
The MDD071A-N-040-N2S-095PR2 is a permanent-magnet synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed to work with digital drive controllers, the unit converts commanded current into precise rotary motion for indexing tables, packaging lines, and medium-speed machining centers. By combining feedback electronics and a blocking brake inside a compact frame, it provides an integrated drive element for multi-axis industrial automation where space, repeatability, and reliable axis holding are important.
Under rated conditions, the rotor develops a continuous stall torque of 2.2 Nm, allowing the axis to resist static process loads without overheating. When motion is required, the winding supports a nominal mechanical speed of 4000 rpm, giving the motor a useful range for feed drives and small spindles. A permanently engaged blocking brake provides 6.5 Nm of holding torque so vertical or suspended loads remain secure after power is removed. Position data is returned through digital servo feedback, allowing the controller to monitor motion precisely during acceleration, steady running, and stopping. Power is transmitted through a keyway shaft, and the connection hardware is located on the right end plate to keep cable routing orderly.
The mechanical envelope uses standard balancing, which helps limit vibration when the rotor is coupled to light machine structures. A locating shoulder with a centering diameter of 95 mm aligns the housing in precision flanges, supporting accurate installation. The motor uses motor size 071 with the short A length code, which keeps the package compact for applications with limited mounting space. The output section is assembled with a shaft seal to limit contaminant entry, and the single-ended shaft leaves no extension on side B. Electrical power and feedback signals are carried through a circular connector that simplifies cable attachment.
