Product Description:

The MAC112A-0-LD-4-C/130-A-0/WI520L/S05 is an AC servo motor manufactured by Bosch Rexroth Indramat and supplied within the MAC AC Servo Motors series. Classified as a motor for analog drives, it converts command voltages from legacy servo amplifiers into controlled shaft torque and speed for positioning tables, feeders, and pick-and-place axes. Integrated tacho and encoder channels return real-time speed and position data to the drive, allowing closed-loop regulation without additional transducers.

With a frame size of 112, the motor uses a larger stator diameter than smaller members of the series, which supports higher torque within the MAC platform. Winding code LD indicates the electrical resistance and inductance used with standard Indramat analog drive modules. Its rated speed is 3000 rpm, so the rotor reaches this velocity under nominal voltage while still producing continuous torque. A centering flange diameter of 130 mm provides precise concentric location on machine gearboxes and helps minimize shaft misalignment. Heat generated in the stator is removed through natural convection, so airflow around the housing must remain unobstructed in cabinet or open-frame installations.

The motor has no blocking brake, so the application must rely on external mechanics or drive torque to hold position when power is removed. The three-phase supply is routed through a connector on side A, allowing cables to drop toward the control cabinet while keeping encoder leads separate from power conductors. Speed feedback is generated at 3 V/1000 rpm by the standard tacho, and the wiring harness also carries signals from the incremental or absolute encoder with tacho feedback used on this model. The motor length code A keeps the overall depth compact, and the standard encoder mounting supports straightforward alignment during installation.
