Product Description:

The MAC112D-0-FD-3-C/130-A-0/S05 is a servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. As a motor intended for analog drives, it converts the drive’s controlled current into rotary motion for positioning and velocity tasks on machine tools, packaging lines, and other automated stations that still rely on analog command interfaces. The motor uses tacho feedback on a second shaft end, so the speed signal is kept separate from the power connection side. This arrangement supports stable speed regulation in legacy motion systems that depend on analog feedback rather than digital encoder communication.

The mounting flange has a centering diameter of 130 mm, which establishes the motor’s mechanical datum when it is bolted to a machine frame. Heat is removed solely through natural convection, so the housing must remain exposed to ambient air to stay within its intended operating temperature range. The armature uses winding code FD, which corresponds to the electrical resistance and inductance values expected by the matching drive. At its rated operating point, the rotor reaches 2000 rpm, a speed that balances torque output with inertial stability for mid-range motion axes. Power conductors enter through a connector on side A, allowing cable runs to remain on one face of the cabinet and simplifying cable routing.

Frame size 112 provides a shaft center height suited to the heavier MAC family loads, while the D length increases the active iron for higher continuous torque without changing the mounting pattern. The tacho generator supplies 3 V/1000 rpm, giving the analog drive a proportional speed signal for closed-loop control. Because the motor is supplied without a blocking brake, holding torque during a power-off condition must be provided by an external mechanical device or by maintaining current through the drive. That setup is common where vertical or overhung loads cannot be left free when input power is removed.
