Product Description:

The MAC071C-0-GS-3-C/095-B-0/5001 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Built as a motor for analog drives, it converts continuous command voltages into torque for positioning tables, spindles, and pick-and-place axes used in industrial automation. Its design pairs a wound stator with a permanent-magnet rotor and includes a tachogenerator on a second shaft end so legacy drive amplifiers can receive a direct speed signal without digital conversion. This arrangement supports closed-loop speed regulation in systems that rely on analog feedback.

The mechanical interface uses a centering diameter of 95 mm, allowing the housing to seat accurately in precision mounting flanges. Heat produced by copper losses is removed through natural convection, so no external blower or liquid circuit is required. Under rated excitation, the rotor reaches 6000 rpm, which is suitable for fast indexing as well as moderate spindle duty. The built-in tachogenerator produces 1.5 V/1000 rpm, giving the analog controller a proportional voltage for velocity regulation. Electrical characteristics follow winding code GS, which sets the resistance, inductance, and current limits used with standard MAC amplifiers.

The motor has no blocking brake, so machines that need holding torque when power is off must rely on external clamping or the drive itself. Power conductors exit through a connector on side B, which can simplify cable routing when the drive is positioned to the right of the motor. Frame designation 071 indicates the stator diameter, while motor length C adds active stack length to increase continuous torque without changing the mounting footprint. Tacho feedback from the second shaft end also gives the drive a direct speed reference for stable operation in analog velocity loops.
