Product Description:

The MAC093A-0-PS-4-C/110-A-0/WI538LX is an AC servo motor engineered by Bosch Rexroth Indramat for inclusion in the MAC AC Servo Motors series. Classified as a motor for analog drives, it interfaces with legacy velocity or position controllers to deliver closed-loop motion in assembly stations, material-handling axes, and general automation equipment. Its electromechanical design pairs permanent-magnet excitation with tachometer or encoder feedback so that the associated drive can regulate both speed and position in real time. This arrangement supports smooth response during starts, stops, and repeated positioning cycles in automated machinery.

During installation, the motor centers on a 110 mm pilot, ensuring concentric alignment with gearboxes or machine frames. Thermal dissipation relies on natural convection, so no external blower is required, and the housing fins radiate heat to ambient air. The rotor can reach a nominal speed of 3000 rpm, which matches the response range of many analog velocity loops. Power conductors terminate through a connector on side A, allowing cables to be routed parallel to the machine wall and reducing bend stress near the entry point. For speed feedback, an integrated tacho generator outputs 3 V/1000 rpm, providing a proportional voltage signal to the drive during changing load conditions.

The mechanical envelope is set by motor size 093, while the compact profile uses motor length A, making the unit suitable for tight mounting zones. Electromagnetic behavior is determined by winding code PS, which matches the stator characteristics expected by the analog amplifier. Position information can be added through the incremental encoder referenced in the type code, enabling index homing or coarse commutation without separate sensors. The motor is supplied without a blocking brake, so holding torque must be provided externally if the axis must remain fixed when power is removed. This layout suits applications where brake-free operation and compact installation are preferred.
