Product Description:

The MAC093B-0-JS-4-C/110-A-2/WI517LX is an AC servo motor built by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Classified as a motor for analog drives, it converts command voltages from legacy controllers into precise mechanical motion. In automated lines, the unit supplies closed-loop speed and position control to axes that require rapid response without digital bus interfaces. Its compact design combines torque production, feedback, and braking in one housing, which helps the motor fit directly to couplings or gearboxes and keeps external wiring straightforward. This arrangement suits retrofit equipment that still relies on analog amplifiers but needs accurate motion during repeated starts, stops, and speed changes.

The mechanical interface is set by a centering diameter of 110 mm, allowing the flange to align concentrically with standard machine frames. The JS winding code identifies the electrical winding used to reach the nominal shaft speed of 3000 rpm. Rotor velocity is supervised by an internal tacho generator that outputs 3 V/1000 rpm, giving the analog drive proportional feedback for velocity loops. The brake can withstand a static torque of 14 Nm, which helps hold suspended or overhauling loads during shutdown and can reduce the need for external holding devices on vertical axes. This combination supports stable low-speed regulation as well as repeatable speed feedback during normal running.

The housing includes a heavy-duty blocking brake, and its friction surfaces release only when the control supply is present. Heat from copper losses escapes through natural convection, so no forced-air accessories are needed when the motor is installed in free air with adequate clearance. Power reaches the stator through a connector on side A, which can simplify cable routing in right-hand cabinet layouts. The frame code 093 corresponds to size 093 with length B, and the standard incremental encoder provides position data to the drive. That feedback signal also helps the controller correct speed drift during changing load conditions.
