Product Description:

Bosch Rexroth Indramat manufactures the MAC117B-0-KS-2-C/130-A-0, an AC servo motor positioned within the MAC AC Servo Motors series. The unit operates as the electromechanical actuator for analog drive systems, supplying the rotary motion necessary to index tools, conveyors, and handling axes in automated machinery. By combining a permanent-magnet rotor with closed-loop speed control, the motor delivers repeatable acceleration and precise velocity regulation that analog amplifiers can track without digital conversion overhead. Its mechanical interface follows standard flange dimensions so integration with existing gearboxes is straightforward.

Mounting is based on a centering pilot of 130 mm, allowing the housing to align accurately with mating flanges and preventing radial runout during high-speed operation. Heat generated in continuous duty is removed by natural convection; no external blower or liquid circuit is required, simplifying cabinet layout. The frame code 117 indicates the stator diameter, while the axial build length marked as B identifies the core stack used for the motor's continuous torque capacity. The motor has no blocking brake, so machinery needing static holding torque must rely on external clamping devices or the drive's current-based positioning mode.

Speed information is returned through integrated tacho feedback, which produces an analog voltage proportional to shaft velocity and enables classic velocity and current loops in legacy drive controllers. The power conductors exit through a connector on side A, which makes cable routing predictable when multiple motors share the same machine wall. Signal resolution adheres to the Standard tacho quality grade, providing sufficient linearity for most positioning cycles without resorting to higher-precision sensors. Winding code KS identifies the coil resistance and inductance used with matching analog amplifiers so the motor operates within its rated torque band.
