Product Description:

The MAC112A-0-LD-3-C/130-A-0/S05 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It is supplied as a motor for analog drives, meaning it pairs with drive controllers that regulate current and velocity through analog command signals in automated machinery. By converting electrical power into precisely metered mechanical rotation, the unit provides closed-loop motion for positioning tables, packaging axes, and similar industrial automation tasks.

The stator and flange share a centering diameter of 130 mm, allowing the housing to seat directly in matching machine frames without additional adapters. Heat is dissipated by natural convection, so airflow around the housing must be maintained instead of relying on an external blower. The LD winding code indicates the electrical resistance and inductance used for applications that require dynamic torque at moderate current. With a nominal speed of 3000 rpm, the rotor can track typical drive command frequencies used in material-handling or robotic lines. Frame size 112 places the motor in a stator diameter group with corresponding shaft height and mounting hole pitch.

The power leads exit through a connector on side A, so cables are routed toward that face for strain relief and EMC grounding. Integrated tachofeedback on a second shaft end generates 3 V/1000 rpm, giving the drive controller a proportional speed signal for continuous velocity regulation. Because the rotor is assembled without a blocking brake, holding torque must come from the drive or an external mechanical lock when power is removed. The feedback device uses standard tacho quality, which is suitable for general-purpose motion axes. The motor also has a compact A length, which helps in installations where axial space is limited.
