Product Description:

The MAC093B-0-GS-4-C/110-A-3/WI520LV/S005 is a servo motor built by Bosch Rexroth Indramat and belongs to the MAC AC Servo Motors series. It is identified as a motor for analog drives that converts drive commands into controlled rotary motion for industrial automation axes. The unit uses a size 093 frame with length code B, allowing direct mounting in medium-power servo stations where velocity and position must be regulated within tight tolerances. In typical installations, the motor works with an external drive amplifier that regulates current, speed, and position through the feedback devices integrated into the housing.

Heat generated in operation is dissipated by natural convection, so external fans or liquid circuits are unnecessary if ambient airflow remains unobstructed. An extra-heavy-duty brake integrated at the tail end clamps the shaft with 22 Nm of torque, preventing back-driving when power is removed. The motor reaches a nominal speed of 4000 rpm, giving drives a wide control bandwidth for packaging, printing, or handling axes that demand fast reversals. Torque is transferred through a shaft with a DIN 6885 keyway, allowing standard couplings to be fitted without additional machining. Precise alignment with gearboxes or linear actuators is maintained by the 110 mm centering diameter that seats the front flange against ISO mounting faces. The keyway arrangement supports direct use with pulleys, couplings, or small gear inputs that require positive mechanical engagement.

The electrical package uses winding code GS, which matches resistance and inductance values used by MAC-series analog drives. Speed feedback for the servo loop is generated by a tachogenerator delivering 1.5 V/1000 rpm, and its output quality is standard for general-purpose motion tasks. A power connector positioned on side A streamlines cable routing along the machine frame and helps keep encoder leads separated from mains conductors. Position data are delivered by an incremental encoder mounted in the standard housing. The tachogenerator supports stable speed feedback for the analog control loop, while the encoder supplies the pulse information used for position monitoring and control.
