Product Description:

The MAC093B-0-JS-4-C/130-B-1/WI522LV 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 reference voltages from legacy drive amplifiers into precise rotary motion for positioning, feed, or spindle duties in automated machinery. Closed-loop feedback allows the connected controller to correct speed deviations as load conditions change during operation. This type of motor is commonly used where older analog servo systems remain in service and reliable rotary response is needed for indexing, feeding, or speed-controlled axes.

With a frame size of 093, the unit follows the medium-sized housing pattern of the series. A centering diameter of 130 mm allows rigid flange mounting while keeping alignment error low. Its rated speed is 3000 rpm, which is the operating speed around which many analog drive controllers regulate. Cooling occurs by natural convection, eliminating the need for external air movers and simplifying enclosure layout when available airflow is limited. The JS winding identifies the wire gauge and turns count used by this motor variant, which influences the motor's electrical characteristics. Position data is provided by a shaft-mounted incremental encoder, while a standard-grade tacho generator supplies 3 V/1000 rpm to the control loop.

Mechanical anchoring is aided by the motor length code B, which sets the active stack height without changing flange geometry. For holding loads, a standard blocking brake is fitted and released electrically when motion is commanded. Power conductors exit through a connector on side B, which helps keep cable routing clear of moving axes in common machine layouts. This arrangement is useful when the motor is mounted near slides, guards, or other components that limit the available cable path around the housing.
