Product Description:

The MAC112D-0-ED-3-C/130-A-0 is an AC servo motor built by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Classified as a motor for analog drives, it is selected for positioning and velocity control tasks in automated machinery where a drive controller issues continuous-time commands to the rotor. The motor’s electromechanical design supports closed-loop regulation through an external drive, allowing the axis to follow reference signals precisely during production or material-handling cycles. This operating concept makes the unit suitable for machines that require smooth speed changes, repeatable motion, and stable response under varying load conditions.

The mechanical interface has a centering diameter of 130 mm, which provides the pilot fit for accurate mounting. Heat generated in the stator is removed by natural convection, so the housing fins must stay clear of obstructions for proper airflow. During rated operation, the shaft can maintain 3000 min⁻¹. This nominal speed suits many machine tool, packaging, and transfer applications that require medium-speed motion. Rotor velocity is monitored by an internal tacho generator that produces 3 V/1000 min⁻¹, providing an analog feedback signal to the controller for speed correction. The magnetic characteristics are associated with winding code ED, which indicates the wire gauge, turns count, and resulting torque constant. Standard tacho quality is specified, indicating normal linearity and ripple values suitable for general-purpose servo loops.

This model is supplied without a blocking brake, so static holding torque must be furnished externally if the load needs to remain fixed during power-off. The stator frame corresponds to motor size 112, and the active stack is identified as length D, giving a clear indication of the motor’s footprint and continuous torque capability. Power conductors exit through a connector on side A, which can help simplify cable routing where installation space is limited. Feedback hardware includes tachofeedback plus a second shaft end, allowing a separate encoder or mechanical load to be coupled without adapter plates. This arrangement can support application layouts that need additional feedback devices or auxiliary mechanical connections at the rear of the motor.
