Product Description:

The MAC090A-0-RD-3-C/110-B-0/S001 belongs to the MAC AC Servo Motors series produced by Bosch Rexroth Indramat. It is an AC servo motor intended for closed-loop positioning and speed control with analog drive amplifiers used in packaging machines, material-handling axes, and other automated stations. The unit follows an analog command signal to provide repeatable motion profiles in cabinet-mounted systems or on open machine frames, making it suitable for applications that require stable speed regulation and precise positioning during continuous production cycles.

This model is supplied with no blocking brake, so any load holding must be handled by the drive or external mechanics. The flange interface carries a 110 mm centering diameter, which aligns the stator housing to a gearbox or machine plate. Heat is removed by natural convection, so airflow around the housing must remain unobstructed. Mains power reaches the winding through a connector on side B, keeping cabling on the rear of the installation clear of the feedback connection. Rotor speed information is generated by tacho feedback with a second shaft end; the tachogenerator produces a proportional voltage, and the auxiliary shaft can be used for an additional sensor or mechanical load without affecting the primary shaft coupling.

The unit operates as a motor for analog drives, so its voltage-to-speed gradient, tachogenerator constant, and current-to-torque curve are scaled for analog control cards rather than digital SERCOS platforms. Internal sensing relies on standard tacho quality, which provides the accuracy required for general industrial positioning tasks. The motor uses the common mounting geometry and electrical pinout found on other frame-90 models, helping it fit established machine layouts where consistent routing and straightforward mechanical alignment are important.
