Product Description:

The MAC112D-6-HD-4-C/130-A-2/AM164SG/S013 is an AC servo motor manufactured by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Integrated into analog drive chains, this motor converts command voltages into precisely regulated torque and speed for industrial positioning and velocity control. Its electrical and mechanical construction supports use on motion axes in packaging, material handling, and automated assembly systems. It is intended for machines that depend on stable response during repeated starts, stops, and speed changes over long production runs.

The motor has a motor size 112 frame and a motor length D stack, giving a balanced ratio between torque density and overall mass. A machined 130 mm centering diameter permits accurate alignment on gearboxes or mounting flanges, reducing radial runout. Under rated excitation, the rotor reaches a nominal speed of 1500 rpm, supporting applications that need steady mid-range speed rather than high spindle speed. Thermal management relies on radial surface cooling, which conducts heat from the lamination stack to external airflow without requiring liquid circuits. This arrangement supports continuous operation in enclosed cabinets when used with the external blower.

A heavy-duty blocking brake is included, and it supplies 60 Nm of braking torque so vertical axes can stay locked during power loss. The auxiliary fan uses a 230 V AC blower mounted to the right of the motor shaft, so cabling can exit parallel to the airflow. Power enters through a connector on side A, keeping the high-current leads separate from the tachogenerator and absolute encoder signal wiring. These feedback devices support closed-loop control by supplying speed and position data to the drive. The right-side blower position also helps maintain a predictable cable path around the motor body.
