Product Description:

The MAC693B-0-OS-2-C/110-A-1/S001 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It serves as a rotary actuator that works with analog servo amplifiers to convert commanded current into controlled torque and speed. In automated equipment, this motor can drive indexing tables, positioning stages, or material-handling axes that require repeatable motion under varying loads. Integrated speed feedback enables the connected amplifier to monitor shaft motion and correct deviations during operation.

The unit dissipates heat through natural convection, so its aluminum housing must remain exposed to ambient air for proper cooling. A 110 mm centering diameter on the front flange allows precise shaft alignment with gearboxes or direct-drive couplings. Coils manufactured according to the OS winding code provide the electrical resistance and inductance required by designated analog drive modules. Speed information is generated through integrated tacho feedback, which delivers a voltage proportional to shaft velocity for closed-loop regulation. All power conductors exit through a connector on side A, keeping cable bends consistent when that side of the motor faces the control cabinet. Adequate clearance around the housing and connector helps preserve cooling airflow while preventing excessive strain on the power cable.

Load holding during power loss is provided by a standard blocking brake, allowing vertical or suspended loads to remain stationary without external clamps. Drive tuning benefits from the motor’s standard tacho quality, which provides repeatable feedback suitable for general-purpose speed-control loops. As a motor for analog drives, the unit works with a servo amplifier that interprets analog command signals and regulates current to the windings. The tacho signal gives the amplifier continuous velocity information, while the blocking brake secures the connected load when motor torque is unavailable. Its flange alignment, side-mounted power connection, and integrated feedback support installation in established MAC-based machine layouts. Proper coupling alignment is important because it limits unnecessary bearing loads and helps the motor deliver smooth rotary motion throughout repeated operating cycles.
