Product Description:

The MAC112A-0-VD-2-C/130-A-0/S005 is an AC servo motor manufactured by Bosch Rexroth Indramat in the MAC AC Servo Motors series. Designed for analog drive systems, the motor supplies closed-loop torque and speed control for positioning axes in industrial automation. By combining field-oriented excitation with feedback, it delivers continuous rotary motion suited for machine tools, printing equipment, and material-handling stations where precise dynamic response is required. The part designation identifies the selected frame size, winding, cooling method, and mechanical interface for this drive platform.

In mechanical terms, the stator housing centers on a 130 mm pilot diameter for repeatable alignment to gearboxes or mounting flanges. Heat from copper losses is removed by natural convection, so no external blower or liquid circuit is required. The unit belongs to motor size 112, which indicates the frame cross-section, shaft height, and bolt pattern used for this motor. During operation, the rotor can reach 2000 rpm at rated voltage, and this nominal speed matches typical analog velocity loops. The integrated tacho generator outputs 3 V/1000 rpm, providing linear speed feedback for precise regulation. Because the motor has no blocking brake, holding torque must come from the drive or an external brake.

The electrical section uses winding code VD, which corresponds to the resistance and inductance values expected by the matching drive card. Rotor velocity is measured by the built-in tacho sensor, and the signal is routed through a dedicated connector on side A so cable runs remain short inside panel layouts. The motor uses tacho feedback, which is sufficient for velocity control tasks on analog drives. The motor uses motor length A, the shortest version within this size class, which helps keep inertia low for faster acceleration without compromising thermal capacity.
