Product Description:

The MAC112D-0-FD-4-C/130-B-3/AM164SG/S013 is a servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Intended for analog drive systems, it converts current commands into regulated shaft motion that supports coordinated positioning, feed control, and other closed-loop tasks on automated machinery. Integrated sensors and a blocking brake allow the motor to hold or release loads as commanded, giving the unit a compact axis solution for both dynamic motion and static load holding. This makes the motor suitable for axes that must accelerate, stop accurately, and remain in place between operating cycles.

The electromechanical profile starts with the built-in extra heavy-duty blocking brake, a mechanical lock that prevents back-driving when power is absent. Its holding capacity reaches 60 Nm, which helps secure vertical or suspended loads during stops and power loss. Heat is removed through natural convection, so the installation space must allow free ambient airflow instead of relying on external blowers. Under rated excitation, the rotor operates at 2000 rpm, a speed that suits analog amplifiers used on medium-inertia axes. A tachogenerator supplies 3 V/1000 rpm, and the integrated feedback arrangement supports stable speed regulation as the drive closes the position loop during motion. The brake and tacho combination is useful where the axis must decelerate smoothly and remain stationary after motion ends.

The centering pilot measures 130 mm, providing a rigid seat against flange faces and helping maintain alignment at the machine interface. Power reaches the stator through a connector on side B, which can simplify cable routing at the non-drive end of the machine. Stator windings use code FD, indicating electrical characteristics intended for legacy TDM and KDS analog controllers. The motor also uses frame size 112, and the D length extends the active lamination stack to increase continuous torque without changing the mounting footprint. A longer magnetic stack also supports continuous-duty operation when the application needs steady torque over repeated cycles.
