Product Description:

The MAC090B-1-PD-1-B/110-A-0/J625/S0 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Classified as a motor for analog drives, it provides closed-loop torque and speed control to machine tools, packaging lines, and material-handling axes that rely on precise electromechanical actuation. It works with legacy drive controllers that use analog command voltages rather than newer digital control interfaces. In service, the motor converts those commands into controlled rotary motion for accurate load positioning in industrial automation cells.

The motor is delivered without a blocking brake, so holding torque must be supplied by the drive or an external mechanism whenever the shaft is at rest. Heat is removed by axial surface cooling, and the integrated fan operates from a dedicated AC 230 V supply to maintain winding temperature during continuous duty. Because the cooling fan has its own supply, airflow does not depend only on shaft speed. Under rated conditions, the rotor reaches 1500 rpm, a speed suited to machines that require moderate velocity with stable operation. A centering shoulder of 110 mm helps align the motor with gearboxes or mounting flanges while keeping runout low.

Power conductors are routed through a connector on side A, allowing cable entry to match common cabinet layouts and simplifying routing at the machine. Motion feedback comes from incremental encoder feedback, which the controller uses for real-time velocity and position loops, and a built-in tachogenerator also provides 3 V/1000 rpm for legacy regulators that use analog speed signals. The electromagnetic characteristics follow the PD winding, which provides the resistance and inductance values expected by the matching power stage. This combination supports stable response in analog control systems where direct feedback signals are used for speed regulation and positioning.
