Product Description:

The MAC090B-0-PD-4-C/110-A-1/WI518LV/S001 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Classified as a motor for analog drives, it converts controlled current from legacy Indramat amplifiers into regulated mechanical motion for industrial positioning and speed-control tasks. The unit serves machine tools, print machinery, and material-handling axes where compact torque delivery, integrated feedback, and passive cooling are preferred. Its operating concept relies on an external analog amplifier and integrated feedback devices to maintain repeatable motion in established automation platforms.

Mechanical alignment is handled by a 110 mm centering diameter that seats the stator face precisely against gearboxes or mounting flanges. Heat removal depends on natural convection, so unobstructed airflow over the housing fins helps keep winding temperature within allowable limits during continuous duty. The rotor is rated for a nominal speed of 1500 rpm, matching the operating range commonly used for stable velocity regulation in analog drive systems. This speed range suits axes that need steady torque and smooth running rather than very high shaft speed. Electrical behavior is indicated by winding code PD, which corresponds to the resistance, inductance, and torque characteristics used for this frame size. A standard blocking brake is integrated at the rear and engages automatically when its 24 V supply is de-energized, helping prevent load drift on vertical or suspended axes.

Velocity feedback is produced by a tacho generator that delivers 3 V/1000 rpm, providing the drive with an analog speed signal proportional to shaft rotation. Power conductors enter through a connector on side A, which can simplify cable routing and keep the motor connection layout straightforward. For position loops, the motor is prepared for tacho feedback, an incremental encoder, or an absolute encoder. It already includes an incremental encoder with standard mounting, so the factory configuration supports motion systems that use incremental position data. This arrangement keeps the motor suitable for older control platforms that continue to rely on analog command structures and conventional feedback processing.
