Product Description:

The MAC071A-0-0S-4-C/095-B-1/WI517LX is an AC servo motor supplied by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed for closed-loop motion on analog drive amplifiers, it converts electrical power into precise shaft rotation to position tooling, conveyor segments, or pick-and-place heads inside automated equipment. The unit employs permanent-magnet excitation and pairs with tachometer or encoder feedback to sustain repeatable speed and position profiles required in indexing tables, light presses, and secondary packaging lines.

The motor’s centering shoulder measures 95 mm, allowing tight axial alignment against gearbox or mounting flanges, and this dimension serves as the reference circle for mechanical coupling accuracy. Its frame is classified as size 071, indicating the stator diameter and helping match inertia and power density across the MAC portfolio. Heat is removed solely by natural convection, so the housing must remain exposed to ambient airflow rather than being enclosed behind panels. Incoming three-phase power reaches the stator windings through a keyed connector on side B, fixing cable exit toward the drive cabinet and easing strain-relief planning. A built-in blocking brake develops 3 Nm of holding torque to secure the shaft whenever the drive is disabled or power is lost.

The compact package is finalized by the short-stack design identified as motor length A, which lowers mass and shortens installation depth without sacrificing nominal torque. Signal integrity is assured by the feedback option listed as tacho feedback with an incremental or absolute encoder; this pairing supplies both velocity tacho pulses and single-turn or multi-turn position data to legacy control loops. As a motor for analog drives, its resolver-less encoder output conforms to voltage levels expected by classic MAC drive cards. When applications only need incremental resolution, the alternate sensing path, specified as an incremental encoder with standard mounting, delivers quadrature signals through the same flange opening, maintaining interchangeability across the series.
