Product Description:

The MAC090A-0-ZD-1-B/110-A-0 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. The unit interfaces with legacy analog velocity and current loops, making it suitable for retrofit or expansion of existing machine modules. Inside an automation cell, it drives indexing tables, feed axes, or pick-and-place arms where accurate torque and position must be maintained under varying load. Its compact format supports installations where dependable motion control is needed without changing the surrounding analog drive architecture.

Its cooling method, feedback devices, and rated speed shape its behavior during continuous duty. Heat is removed solely by natural convection, so cabinet airflow or surrounding free air must keep the stator within permissible temperature limits. Because it is delivered without a blocking brake, holding torque must come from the drive or an external mechanical latch whenever the shaft must stay fixed after power is removed. Commanded speed peaks at 1500 rpm, a nominal rating that suits moderate-speed machining and conveyor applications. Rotor position is monitored through incremental encoder feedback, enabling the drive to maintain accurate velocity regulation during changing process conditions. For velocity verification, the integrated tacho generator outputs 3 V/1000 rpm, providing a linear analog signal proportional to shaft speed.

The mechanical interface is organized around a centering pilot diameter of 110 mm, allowing rigid coupling to gearboxes or mounting flanges with minimal runout. Power conductors are routed through a connector on side A, which can simplify cable routing when several motors are installed along a common machine wall. Classified as a motor for analog drives, it matches drive amplifiers that regulate current with ±10 V reference signals instead of fieldbus commands. The electromagnetic design follows the ZD winding code, which sets the resistance and inductance values used by the matching amplifier. This arrangement supports stable operation in equipment that depends on established analog control hardware.
