Product Description:

The MAC093B-0-OS-4-C-110-B-1-AM164SG is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It is intended to drive analog-controlled axes in automated machinery by converting command signals from the drive into precise rotary motion for positioning tasks. Integrated tachogenerator and encoder feedback allow the paired drive to regulate velocity and angular position without extra sensors, making the motor suitable for transfer lines, tooling equipment, and packaging stations that require closed-loop motion.

The rotor flange provides a centering diameter of 110 mm, permitting direct mounting to gearheads or machines with matched pilot recesses. Under rated conditions, the shaft reaches 2000 rpm, a speed that balances torque production with thermal limits for this frame. Heat generated at that operating point is removed solely by natural convection, so airflow around the housing must remain unobstructed. The stator frame uses size 093, which keeps bolt patterns and shaft height consistent across the series. Tachogenerator output is calibrated for 3 V/1000 rpm, delivering a proportional voltage that the analog drive uses for real-time speed feedback.

Electrical power is routed through a connector on side B, keeping the feed separate from feedback plugs on the opposite face and simplifying cable runs in compact cabinets. The stator uses an OS winding with resistance and inductance values matched to Indramat analog drives in this torque class. Axial length is identified by length code B, and this stack depth supports the continuous torque expected for medium-duty motion without excessive motor overhang. For position control, the unit carries an absolute encoder, providing the drive with a unique shaft angle reference immediately after power-up. A standard blocking brake holds the load when the system is at rest.
