Product Description:

The MAC071C-0-NS-4-C/095-B-0/WI511LV is a servo motor manufactured by Bosch Rexroth Indramat and supplied within the MAC AC Servo Motors series. Designed as a motor for analog drives, it converts command voltages from legacy servo amplifiers into precise shaft rotation for positioning or speed-regulated tasks on production machinery, printing lines, and material-handling axes. Its electromechanical design supports direct coupling to gearboxes or load shafts, allowing the drive controller to implement closed-loop motion control in industrial automation cells.

A centering diameter of 95 mm aligns the flange with machine frames, ensuring concentric seating when the motor is bolted in place. Heat from the stator is removed by natural convection, so no external blower or liquid circuit is required. At its rated operating point, the rotor turns at 3000 rpm, a nominal speed commonly used by analog servo amplifiers. The electromagnetic characteristics are set by the NS winding code, which indicates phase resistance and inductance for stable current control. Power reaches the stator through a connector on side B, keeping cables clear of the driven load.

The motor frame follows size code 071, giving a compact diameter that balances inertia against continuous torque requirements in medium-duty axes. The motor has no blocking brake, so the application must rely on drive torque or an external clamp to secure the load at standstill. Speed feedback for older analog controllers is provided by a built-in tacho generator that outputs 3 V/1000 rpm, and this linear voltage simplifies velocity loop tuning without digital scaling. For position tasks, the unit carries an incremental encoder with standard mounting, allowing quadrature pulse feedback to modern motion cards while preserving the original tacho output for redundancy.
