Product Description:

The MAC071C-0-GS-3-C/095-A-0/S01 is an AC servo motor built by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Classified as a motor for analog drives, it converts controller commands into rotary motion for positioning, indexing, or continuous speed regulation in automated machinery. Its compact format suits packaging lines, printing equipment, and material-handling axes that depend on closed-loop motion control. Because the motor is used with an external amplifier, current regulation and motion commands are handled outside the housing, which helps keep the motor compact while supporting responsive axis behavior.

A centering register of 95 mm fixes the housing concentrically to the machine frame, helping maintain runout accuracy during operation. Heat generated by the stator is removed through natural convection, so extra fans or liquid circuits are unnecessary when surrounding air can circulate freely. The shaft can reach a nominal speed of 6000 rpm, which supports high-cycle processes that still require stable servo response. Power enters through a keyed circular connector on side A, which sets cable routing at the machine. The rotor is assembled without a blocking brake, so any hold-in-place requirement must be provided by drive torque or an external mechanical latch.

Speed feedback is supplied by an integrated tacho generator, and its output of 1.5 V/1000 rpm allows the analog drive to calculate velocity directly. The GS winding code indicates the electrical winding arrangement used for this motor and matches it to compatible drive current ranges. The motor uses stator length C with frame size 071, giving a compact package for machines where installation space is limited. A second shaft end lets the tacho and the driven load share the same mechanical reference, which helps the feedback system track motor speed without a separate digital encoder. It also keeps the feedback hardware mechanically linked to the motor shaft during operation.
