Product Description:

Bosch Rexroth Indramat's MAC071C-0-NS-3-C/095-B-0/S01 is an AC servo motor in the MAC AC Servo Motors series. Built as a motor for analog drive systems, it converts regulated current from a drive amplifier into mechanical rotation for positioning and velocity control on packaging, material-handling, and tooling equipment. Its electrical interface accepts proportional speed references from ±10 V command signals common in legacy control platforms. This operating style suits machines that use amplifier-based motion control and require stable response during repeated cycles. The motor is supplied without a blocking brake, so holding torque must be provided by the drive or by an external mechanism when the axis is idle.

The motor has a centering diameter of 95 mm, allowing the housing to seat concentrically in standard machine shoulders. Heat generated in the stator is removed by natural convection, eliminating the need for fans or liquid circuits and keeping the installation simple. The feedback system is configured with tacho feedback and a second shaft end; the tacho produces an analog speed signal, while the auxiliary shaft can carry an external encoder or coupling. The shaft reaches a nominal speed of 3000 rpm, letting the drive deliver constant torque across typical machine cycles. Internally, winding code NS identifies electrical values matched to legacy MAC drive modules.

The motor has a frame designation of 071 and a body length of C, which correspond to its housing size and active iron length. This combination provides a longer active stack than shorter versions of the same frame. Power conductors enter through a connector on side B, positioning the cable away from the driven load and simplifying routing near the mounting face. The tacho generator delivers 3 V/1000 rpm, giving the analog controller a linear speed reference for closed-loop regulation.
