Product Description:

The MAC115B-0-GS-4-C/130-A-1/WI524LV/S001 is an AC servo motor produced by Bosch Rexroth Indramat and assigned to the MAC AC Servo Motors series. It is engineered for analog drive controllers that require precise torque and speed regulation on production lines, material-handling axes, and machining centers. The 115 frame code places it in the mid-range of the series, and the B length gives a compact housing that still supports direct-coupled industrial loads. This combination suits machines that need repeatable motion while keeping the motor body reasonably compact.

The electromechanical profile includes a blocking brake that delivers 45 Nm of holding torque, giving vertical or suspended axes a mechanical lock whenever power is removed. Accurate shaft alignment is aided by a 130 mm centering diameter that mates with standard flanges and helps the motor seat correctly during installation. Heat is removed solely through natural convection, eliminating the need for forced air or liquid circuits and simplifying enclosure layout. Under rated excitation, the rotor reaches 2000 rpm, matching common spindle and feed-drive requirements in general automation. The winding code GS indicates the electrical characteristics used by compatible analog amplifiers for proper current control.

Mechanical transmission is handled by a DIN 6885 keyway on the shaft, allowing repeatable coupling with standard driven elements. Velocity feedback to the drive is delivered by a tacho generator that produces 3 V/1000 rpm, while incremental encoder signals provide position data for closed-loop motion control. Power leads exit on side A through a sealed connector, which helps keep cable routing consistent when several axes are mounted in the same machine. With a frame designated as size 115, the motor offers a practical balance of torque density and inertia for pick-and-place robots, gantry drives, and similar medium-duty applications. Its overall layout supports stable operation where dependable feedback, predictable braking behavior, and straightforward mounting are required.
