Product Description:

The MAC071A-0-0S-3-C/095-B-0/S001 is an AC servo motor manufactured by Bosch Rexroth Indramat and assigned to the MAC AC Servo Motors series. It functions as a closed-loop actuator for industrial machinery driven by analog amplifiers, converting electrical control signals into mechanical motion for precise axis control in assembly lines, packaging systems, and similar automation tasks. It is categorized as a motor for analog drives, so its electrical interface matches legacy controller families that regulate current continuously rather than through digital pulse techniques.

The motor uses a centering diameter of 95 mm, so the pilot fits snugly into matching machine housings and helps keep radial misalignment low. Heat produced by the stator windings is removed through natural convection, eliminating the need for forced air or liquid circuits. Frame designation 071 indicates the exterior flange pattern used for this motor size and places the unit in a power class common to medium-size servo axes. Length code A denotes the shortest rotor stack in this size, which helps reduce inertia for faster acceleration. For streamlined wiring, the three-phase power connector is arranged on connector on side B, allowing cable entry at the rear of typical drive enclosures while keeping feedback lines separated from mains conductors.

Mechanical holding is handled externally because the motor has no holding brake, so applications that require static load support must add external locking or maintain motor torque when disabled. The feedback package combines tacho feedback and a second shaft end, delivering an analog speed signal while also providing a through-shaft for an auxiliary encoder or fan. Speed sensing accuracy follows the manufacturer’s standard tacho quality level, which is adequate for most velocity loops that rely on analog regulation.
