MDD071B-N-060-N2S-095PL0
The MDD071B-N-060-N2S-095PL0 is a compact synchronous servo unit produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Intended for use with digital drive controllers, the device converts regulated three-phase power into precise shaft rotation for automated assembly lines, packaging cells, and material-handling stations. Its standard housing resists contamination commonly found in production areas, and the balanced rotor supports smooth operation across the speed range. A keyed shaft end connects directly to couplings, which helps simplify installation on equipment that requires accurate rotary motion.
The motor frame uses a 95 mm pilot diameter for repeatable alignment to gearboxes or mounting surfaces. Under stall conditions, it delivers 4.4 Nm of continuous torque, allowing the axis to maintain load without thermal overload. During motion, the rotor follows command sequences up to 6000 rpm, and this speed capability is supported by the compact winding layout used with size code 071 laminations. Electrical power and feedback exit on the left side, and a sealed connector block helps keep field wiring orderly. Because the motor is supplied without a blocking brake, an external holding device is required when the axis must remain fixed after power is removed. The single-ended shaft arrangement and standard dynamic balancing support steady operation during acceleration and deceleration.
Position accuracy is maintained by the integrated digital servo feedback (DSF) interface, which transmits rotor position data to the controller at high update rates. Fluid ingress protection is improved by a design with a shaft seal at the front bearing, helping extend service life in lubricated machine compartments. The stator uses length code B, which indicates the active iron stack and balances thermal capacity with compact dimensions. This combination allows the motor to support closed-loop motion tasks where stable speed regulation and precise positioning are required.
