Product Description:

The MAC112D-0-ED-4-C/130-A-0/WI520LX/S05 is an AC servo motor manufactured by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Intended for analog drive configurations, the unit translates velocity and position commands into controlled rotary motion for industrial axes such as pick-and-place arms, indexing tables, and conveyor sections. Its design combines a specific winding and feedback package so that stable operation is maintained in demanding motion-control applications.

For mechanical integration, the motor is built in frame size 112 with a housing length marked D, a combination that balances mounting space against continuous torque capability. Under rated excitation, the shaft reaches 3000 rpm, allowing direct coupling to many loads without intermediate gearing. Heat generated during this duty is dissipated through natural convection, so installation must ensure unobstructed airflow around the finned surface. Positioning accuracy during assembly is supported by a 130 mm centering diameter that seats the motor concentrically on the machine plate and minimizes radial misalignment. Keeping the frame within this dimensional envelope also limits rotor inertia, which shortens acceleration times when coordinated axes demand rapid indexing. Because no forced ventilation is used, duty cycles must remain within the continuous current range for convection-cooled operation.

The electrical package is identified by winding code ED, which matches the stator impedance to analog drives that supply the required current and voltage ranges. Power enters through a connector on side A, simplifying cable routing inside cabinets that mount the motor with its shaft toward the process. For speed feedback, a 3 V/1000 rpm tachogenerator is combined with an incremental encoder, providing both coarse velocity information and fine position pulses to the drive. This feedback set enables closed-loop regulation, while the absence of a blocking brake allows the axis to freewheel when power is removed in applications that rely on external mechanical locking.
