Product Description:

The MAC090B-0-ND-4-C/110-B-1/WI524LX is an AC servo motor produced by Bosch Rexroth Indramat. It belongs to the MAC AC Servo Motors series and is intended for closed-loop positioning in automated machinery. When paired with analog control amplifiers, the unit delivers precise torque and speed regulation on rotary axes used in material handling, packaging, and general factory automation. Its feedback system allows the connected amplifier to monitor motor motion continuously during operation. This operating role makes it suitable for indexing, transfer, and positioning tasks that require repeatable response.

The motor seats against machine frames through a centering ring that measures 110 mm in diameter, allowing coaxial alignment with gearboxes or direct-drive loads. Heat generated in the stator is removed by natural convection, so no forced air or liquid circuit is required during continuous duty. Power conductors enter the housing through a connector on side B, which keeps cable egress away from the driven shaft and can simplify cable routing. A blocking brake is integrated to hold the rotor when power is removed, preventing unintended motion on vertical or high-inertia axes. Rotor position is referenced with an incremental encoder mounted in the feedback stack, and the drive uses its pulse trains for real-time velocity and displacement data.

Additional speed feedback is provided by the tachofeedback option, which supplies signals used by the drive for closed-loop speed control. Because it is a motor for analog drives, the winding voltage constants and signal levels match legacy Indramat control hardware used in older cabinets. The unit maintains a standard tacho quality classification, which supports stable ripple and gain behavior across the usable speed range. This arrangement suits retrofit applications where existing analog electronics are retained. The combined encoder and tacho signals support steady control behavior without changing the basic machine layout. It also helps preserve compatibility with installed control interfaces while improving motion performance.
