Product Description:

The MAC117E-0-ES-2-F/180-B-1/S001 is a servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. As a motor for analog drives, it converts electrical energy into tightly regulated mechanical rotation for axes that are governed by proportional amplifiers rather than digital controllers. Within automated production cells, the unit provides responsive torque and speed, supporting material handling, packaging, and forming operations where coordinated motion is required. Its operating concept suits machines that rely on stable response and direct speed regulation during repeated motion cycles.

Mechanical interface data describes how the motor is installed on equipment. A centering diameter of 180 mm aligns the flange precisely on the machine frame and distributes reaction forces evenly. Thermal management is passive because the housing is cooled by natural convection, so no external fan or liquid circuit is necessary. During stops, a standard blocking brake locks the shaft and prevents load back-driving when power is removed. Velocity feedback is generated through tacho feedback, supplying an analog speed signal to the drive for proportional control. Power conductors are routed through a connector on side B, which simplifies cable runs when the motor is mounted in deep enclosures.

Dimensional coding indicates the electromagnetic package. The designation motor length E indicates an extended stator stack that yields higher continuous torque than shorter versions of the same frame. Frame classification motor size 117 specifies the stator diameter and determines compatible couplings and gearboxes. Stator windings follow winding code ES, matching impedance values to analog drive outputs so current regulation remains stable across the speed range. For applications such as gantry axes where speed ripple can disturb cut quality, the motor incorporates increased smooth-running quality, achieved through precise commutation and rotor balancing to minimize velocity fluctuation under constant load. This helps the motor maintain steady motion in processes that depend on uniform axis travel.
