Product Description:

The MAC112D-0-FD-4-C/130-A-2/AM164SG/S013 is an AC servo motor produced by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Designed for integration with analog drive controllers, the unit supplies closed-loop torque and speed control to automated stations, gantries, and transfer lines. By combining electrical commutation with integrated feedback, it translates command signals into precise mechanical rotation that maintains positioning accuracy across varying load conditions. It features a permanent-magnet rotor and stator windings suited to medium-frame machinery, allowing the axis to start, stop, and hold loads under tight cycle-time requirements common in packaging or material-handling cells. Its integrated feedback also helps the drive correct speed deviations as operating loads change.

As a motor for analog drives, the unit accepts current commands from legacy velocity or torque loops. A heavy-duty blocking brake is fitted, delivering 60 Nm of static holding torque so vertical or indexed axes remain locked when power is removed. A pilot diameter of 130 mm aligns the housing to the machine frame, and the active magnetic stack corresponds to motor length D. Heat is dissipated by natural convection, eliminating the need for forced airflow. Under rated excitation, the shaft reaches 2000 rpm, giving balanced dynamics for medium-inertia loads, while three-phase power is supplied through a connector on side A. Integrated tacho feedback provides speed and position data to the connected controller.

The 112 frame pairs with the D-length core to increase continuous power density without excessive mass. Stator conductors follow the FD winding code, allowing the drive to reach nominal flux with moderate current. The tacho generator delivers 3 V/1000 rpm, a level suited to precise velocity feedback in analog loops. For absolute position capture, the motor can use an absolute encoder, which allows position data to remain available after power restoration.
