Product Description:

The MAC112D-0-FD-3-C-130-A-0/S005 is an AC servo motor manufactured by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. It is designed for analog drive systems that issue continuous voltage commands to regulate speed and torque in automated production lines, packaging machinery, and material-handling axes. Its analog operating concept suits systems that use voltage-based command and feedback loops rather than digital networked motion control. This arrangement supports steady speed regulation and repeatable rotary motion in machines that depend on smooth, predictable axis response.

The motor centers on a precision pilot of 130 mm, simplifying coaxial mounting with gearboxes and couplings. Thermal energy is removed through natural convection, so the housing must stay unobstructed rather than rely on forced airflow. A winding designation of FD identifies the wire gauge and slot fill used for moderate current density and stable thermal rise. When energized at its rated voltage, the shaft reaches 2000 rpm, giving a usable speed range for belt-driven or direct-drive applications. Closed-loop control is supported by an internal tachogenerator that produces 3 V/1000 rpm, allowing the analog controller to translate shaft velocity into a proportional feedback voltage.

The motor has Motor size 112 and Motor length D, which provide a longer magnetic stack while preserving the 112 mm frame width used in the series. Power conductors enter through a connector on side A, so enclosure layouts must leave service space on that end of the motor. The rear extension includes tacho feedback and a second shaft end, enabling attachment of an auxiliary encoder or a mechanical load without disturbing the primary coupling. Because a blocking brake is not present, the installation must rely on drive torque or an external clamp to hold position during power-off conditions. The passive cooling arrangement also reduces the number of components that require routine service.
