Product Description:

The MAC071C-0-JS-3-C/095-B-1/8 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Intended for analog drive systems, it transforms command voltages into controlled shaft rotation for positioning, velocity, and torque functions in automated equipment. Mid-range frame dimensions, a standard blocking brake, and second-shaft feedback options make the unit suitable for vertical axes, indexers, and other machinery that require secure holding capability when power is removed.

The integrated brake supplies 3 Nm of holding torque, providing adequate resistance against moderate loads during idle periods. Accurate flange alignment is supported by a centering diameter of 95 mm, which helps maintain concentricity with couplings or gearboxes. Thermal energy leaves the housing through natural convection, eliminating the need for external blowers when ambient airflow is available. Speed feedback is delivered by tacho feedback and a second shaft end; the tacho produces an analog signal that mirrors rotational speed, and the auxiliary shaft permits an additional encoder for higher-resolution monitoring. The electrical design targets a nominal running speed of 2000 rpm, which suits common machine-tool and transfer-line applications.

Power conductors exit on connector on side B, simplifying cable routing when the motor face is oriented toward the operator. The tacho generates 3 V/1000 rpm, allowing analog amplifiers to scale velocity loops without extra conditioning hardware. Mechanical proportions use frame size 071 with length code C, balancing continuous torque capacity against overall depth and helping with installation in compact spaces. Winding code JS indicates phase resistance and inductance values used with legacy MAC drives. This arrangement supports use in printing presses, packaging stations, and indexing tables that still rely on analog control loops.
