Product Description:

The MAC093B-O-JS-4-C/110-A-0/WI522LV is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It is a motor for analog drives, so it suits retrofit systems and legacy control loops that rely on proportional voltage commands instead of fully digital interfaces. In automated assembly lines, the motor converts commanded current into precise rotary motion, allowing linear actuators, indexing tables, and packaging spindles to maintain repeatable positioning while loads change during normal operating cycles.

The centering diameter of 110 mm aligns the motor case with mating gearheads and helps reduce radial offset during installation. Rated shaft speed reaches 3000 rpm, giving the drive a broad operating range for mid-speed motion profiles and responsive acceleration during ordinary positioning moves. Power conductors exit through a connector on side A, which simplifies cable routing where connections must be directed to one side of the machine. Speed feedback is generated by an internal tacho that delivers 3 V/1000 rpm, and electromagnetic behavior follows the JS winding code, which corresponds to the electrical characteristics expected by the matching drive module.

The motor uses size 093 and length code B, which keep rotor inertia moderate and help the unit respond quickly during short indexing moves. Because the assembly is supplied without a blocking brake, any holding function during power loss must come from the drive or an external clamp. The feedback arrangement includes tacho feedback with an incremental or absolute encoder, and the integrated incremental encoder supports closed-loop positioning while the analog speed loop remains available. This combination allows the motor to serve packaging, material-handling, or light machine-tool axes that still depend on analog velocity control but benefit from added position feedback.
