Product Description:

The MAC112D-1-FD-2-C/130-A-2/S013 is an AC servo motor built by Bosch Rexroth Indramat for use in the MAC AC Servo Motors series. Classified as a motor for analog drives, it is installed in positioning axes and processing modules that require precise velocity regulation and quick stopping capability. A heavy-duty blocking brake is integrated so loads can be held when power is removed, and the unit is arranged for axial surface cooling systems used in high-duty cycles. This layout is suitable for equipment that must alternate between controlled motion, short dwell periods, and repeatable stopping points during production.

For mechanical alignment, the front flange carries a centering pilot of 130 mm. The housing accepts forced air through an Axial Surface Cooling jacket that is assisted by an external blower rated at AC 230 V. This cooling arrangement stabilizes winding temperature when the rotor turns at the nominal speed of 2000 min⁻¹. When the brake is energized, a holding torque of 60 Nm locks the shaft, allowing vertical or overhung loads to stay in place without supplementary clamps. Heat generated by copper losses is drawn away from the frame ribs, and the D-length frame supports stable magnetic loading across the cooling path.

Rotor speed is reported by an internal tachogenerator, and the drive receives this analog signal through the tacho feedback circuit, which outputs 3 V/1000 min⁻¹ at reference velocity. Power conductors enter through a connector on side A, streamlining cabinet layout in tight assemblies and helping keep cable routing direct. The stator windings follow Winding Code FD, providing electrical constants that match Bosch Rexroth Indramat analog amplifiers. Motor size 112 with frame length D provides the moment of inertia needed for medium-mass loads, while the standard tacho quality supports repeatable speed detection within the permitted tolerance band.
