Product Description:

The MAC093B-1-GS-4-C/110-A-1 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. As a motor for analog drives, it supplies tightly regulated torque and speed so that indexing tables, packaging axes, or material-handling gantries can follow precise motion profiles inside industrial automation cells. It forms the electromechanical interface between the drive amplifier and the mechanical load, translating commanded current into synchronized rotation while maintaining feedback for closed-loop control.

Its nominal speed is 4000 rpm, which makes it suitable for fast traverse cycles. Heat produced at that speed is removed through axial surface cooling assisted by an external blower that runs on AC 230 V. This airflow keeps winding temperature below insulation limits during continuous duty. Precise alignment with gearboxes or mounts is supported by the 110 mm centering diameter, which provides a repeatable mechanical reference. The tacho generator produces 1.5 V/1000 rpm, giving the analog drive a proportional velocity signal, and its quality is listed as standard for routine control accuracy. A standard blocking brake holds the shaft when power is removed, while the feedback channel can accept incremental or absolute encoders so position data matches the needs of the associated controller.

The physical envelope follows the series coding: the 093 frame size provides a compact stator diameter, and the B length extends the active iron for higher continuous torque than shorter variants. Electrical power is routed through a connector on side A, simplifying cable routing where multiple axes are installed in line. The GS winding code identifies the winding layout used in this motor, allowing the analog amplifier to supply the appropriate current characteristics.
