Product Description:

The MAC112B-0-PD-2-C/130-B-0/S005 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Classified as a motor for analog drives, it converts current-loop commands into precise rotary motion for automated machinery. By providing torque that is directly proportional to armature current, it supports position and speed control in legacy packaging lines, printing presses, and material-handling axes where analog tachometer feedback is preferred. Its operating concept fits machine systems that use current commands and direct motor feedback rather than digital communication between the motor and drive.

The mechanical format follows motor size 112, which gives the frame a standardized mounting interface for medium-torque machinery. The length B housing uses a deeper active core to support continuous output in this frame size. Under rated excitation, the rotor reaches 1500 rpm, a speed suited to analog velocity loops. Heat is removed by natural convection, so the installation should leave free airflow around the housing. Because the motor is supplied without a blocking brake, vertical axes require an external holding device when power is removed. The PD winding code matches the motor’s intended speed and torque combination for this configuration.

The flange is machined with a 130 mm centering diameter, allowing direct coupling to gearboxes or plates that match the DIN 42955 interface. All three phases are routed through a connector on side B, which helps keep cable routing consistent in rear-cabinet layouts. Speed information is generated by the integral tacho generator; the feedback method is tacho feedback, and it delivers 3 V/1000 rpm to the drive for analog loop closure. This arrangement provides a direct speed signal for the control loop without requiring a separate encoder. The motor therefore suits installations that continue to use analog feedback architecture for regulated motion.
