Product Description:

The MAC071C-0-NS-4-C/095-B-1/WI520LV is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed for analog drive systems, the unit converts command voltages into proportional torque and speed for axes that require precise velocity regulation. Within automated assembly lines or packaging equipment, it delivers closed-loop motion while its tacho generator and encoder feedback signals allow the connected controller to measure actual shaft movement in real time.

The built-in blocking brake applies 3 Nm of holding torque, preventing shaft rotation when the drive is disabled or power is removed. A centering flange of 95 mm simplifies alignment with gearboxes and machine plates, helping keep radial runout low. Heat produced by the stator windings is dissipated through natural convection, so no external fan or liquid circuit is required and the motor can be placed in sealed cabinets with limited airflow. Under rated conditions, the rotor reaches 3000 rpm, allowing straightforward gear ratio selection. The C length code enlarges the magnetic stack to increase continuous torque without pushing the motor beyond the standard housing format for this series.

Power conductors are routed through a connector on side B, letting cable routing stay clear of adjacent axes and simplifying service loops. The built-in tacho generates 3 V/1000 rpm, providing a linear voltage reference that supports stable speed-loop feedback without additional scaling hardware. For position tasks, an incremental encoder with standard mounting delivers high-resolution angle data to the drive. The stator uses the NS winding code, which sets the phase impedance and flux linkage so the motor pairs correctly with Indramat analog amplifiers. Frame size 071 sets the shaft height and mounting bolt circle, and the C-length version shares the same mounting footprint as other MAC motors while providing higher continuous output.
