Product Description:

The MAC112D-0-FD-3-C/130-A-1 is an AC servo motor built by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Intended for analog drive controllers, it supplies torque and speed control for automated positioning tables, pick-and-place axes, and packaging stations. The unit is delivered with tacho feedback and a second shaft end, allowing one side to supply velocity feedback while the opposite side couples directly to a mechanical load. This arrangement supports applications that need external velocity monitoring while still leaving the main shaft available for power transmission to the driven mechanism.

The mechanical interface follows a centering diameter of 130 mm, allowing the housing to align precisely inside standard machine flanges. Heat is removed solely by natural convection, so cabinet layouts must permit vertical airflow around the ribbed frame. A built-in blocking brake rated at 45 Nm secures vertical loads when the drive is disabled. During operation, the rotor reaches its nominal speed of 2000 rpm; at this speed, the tacho generator produces 3 V/1000 rpm, delivering an analog velocity signal to the controller. Power conductors enter through a connector on side A, simplifying cable runs in multi-axis racks. Tacho quality is specified as standard for general-purpose motion applications.

The motor size code is 112, which indicates the frame cross-section and shaft height used across the MAC family. Within that size, the length designation D provides additional active iron and copper for higher continuous torque than shorter variants while keeping the same mounting pattern. This longer body section increases the active motor length without moving the unit outside its established frame class. Electrical behavior is tied to winding code FD, which corresponds to phase resistance and inductance suited to drives that use the standard MAC bus voltage and require moderate base speed.
