Product Description:

The MAC071C-0-NS-4-C/095-A-0/WI538LV is an AC servo motor produced by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Intended for integration with analog drive amplifiers, it converts commanded electrical current into tightly regulated rotary motion used for positioning and speed control in automated packaging, pick-and-place, and print-handling stations. Matched feedback devices help keep control loops stable during the rapid duty cycles common in industrial assembly lines.

The stator housing carries a centering flange with a diameter of 95 mm, allowing accurate seating on gearboxes or mounting plates and minimizing radial runout. Heat generated in the windings leaves the frame by natural convection, so no external blower or liquid circuit is required and cabinet airflow remains uncomplicated. Electrically, the winding code NS identifies the phase resistance and inductance selected for medium-voltage inverters, allowing stable current control across the speed range. At a nominal speed of 3000 rpm, the rotor supports common servo operating ranges while retaining headroom for dynamic motion profiles. Power conductors exit through a plug-style interface on side A, which simplifies harness routing in compact axis modules.

Mechanical holding force must be handled externally because the motor has no blocking brake, which reduces moving mass and inertia during rapid reversals. For velocity feedback, the integrated tacho generator delivers 3 V/1000 rpm, supplying a linear analog signal to classic drive cards, while the secondary incremental encoder provides high-resolution position data for digital overlays. The frame designation 071 indicates the shaft-height class shared across the MAC series, allowing compatibility with standardized couplings and planetary gear stages. The motor also uses length variant C, which gives this frame its corresponding axial housing length.
