Product Description:

The MAC112D-0-HD-2-C/130-A-1/S05 is a brushless AC servo motor built by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It is intended for integration with analog drive controllers where it delivers closed-loop speed and position control for automated machinery, packaging lines, and material-handling axes. The motor converts electrical power to rotary motion while providing speed feedback through a tachogenerator so that the connected drive can regulate acceleration, deceleration, and steady-state running. Because the feedback is generated at the motor, the drive can respond quickly to changes in load during normal machine cycles.

Its holding capability is supplied by an internal blocking brake rated at 45 Nm, allowing vertical or indexing loads to remain stationary when power is removed. A centering diameter of 130 mm aligns the housing with mechanical frames and helps maintain concentric mounting. Heat produced in the stator is dissipated by natural convection, removing the need for external blowers and simplifying enclosure design. Under nominal excitation, the shaft turns at 1500 rpm, a speed that matches common gear ratios in transfer systems. Electrical power enters through a single cable interface with a connector on side A, which keeps service access on the same face of the machine. This layout can simplify cable routing in compact machine frames.

This dimensional variant uses motor length D, which provides additional active iron for higher continuous output without changing the flange. The frame classification of motor size 112 matches a standardized mounting pattern. A tightly wound stator with the HD winding code achieves the required torque with reduced current, which can support smaller amplifier sizing. Speed information is supplied by the tacho generator, which delivers 3 V/1000 rpm and allows the analog drive to detect load changes quickly and adjust armature voltage accordingly. The longer active section is useful where higher continuous performance is needed within the same general mounting envelope.
