Product Description:

The MAC090A-0-RD-3-C/110-A-1/S001 is an AC servo motor positioned within the MAC AC Servo Motors series and built by Bosch Rexroth Indramat. It operates as a drive element for position and speed control in industrial automation where analog command interfaces remain in service. The motor converts electrical input from compatible drives into controlled rotary motion and supplies feedback for closed-loop regulation of axis movement. It is suited to machine axes that rely on stable analog response during repeated starts, stops, and speed changes in existing production equipment.

A centering diameter of 110 mm facilitates concentric mounting to gearboxes or machine frames and keeps the stator aligned with the driven mechanics. Heat generated by copper losses leaves the housing through natural convection, so no external fan or coolant circuit is required. Power conductors enter through a connector on side A, allowing consistent cable routing when multiple axes are installed in parallel. Rotor speed is measured by tacho feedback taken from the second shaft end, providing an analog voltage proportional to rpm for velocity loops. This arrangement supports steady speed control on equipment that depends on continuous analog feedback.

The unit is delivered with a standard blocking brake that clamps the shaft whenever the brake circuit is de-energized, preventing load drift on vertical or suspended axes. This is useful on lifting axes and other installations that cannot tolerate movement at standstill. Its designation as a motor for analog drives makes it suitable for legacy controller platforms that issue ±10 V speed or torque references. The motor uses a 090 frame size, so its mounting envelope and electrical connections match related units in the product line. The velocity transducer uses a standard tacho quality grade, delivering repeatable feedback accuracy for moderate-precision tasks such as indexing tables or winding systems.
