Product Description:

The MAC112D-2-ED-4-C/130-A-2/AM164SG/S018 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed for integration with analog drive amplifiers, it converts voltage commands into controlled shaft rotation for industrial automation tasks such as indexing tables, gantry axes, and material-handling equipment where repeatable positioning and holding capability are required. It is intended for controlled rotary motion in equipment where axis response must remain consistent through repeated production cycles. Because it works with analog amplifiers, it is suited to motion platforms that separate the motor from the control electronics and rely on external loop regulation.

This model employs a heavy-duty blocking brake that delivers 60 Nm of static torque to secure vertical or offset loads whenever the drive is disabled. Thermal management relies on a frame-mounted blower rated at AC 115 V, which forces cooling air along the stator. Installation is aided by a centering pilot of 130 mm, which helps maintain concentric alignment against the machine flange. The motor uses axial surface cooling, so heat transfers through ribbed exterior surfaces rather than the shaft. During continuous duty, the rotor reaches a nominal speed of 3000 rpm, which suits applications that need mid-range velocity without sacrificing torque density. The forced airflow helps stabilize winding temperature during extended operation at low shaft speeds, when natural heat removal would be less effective.

Power enters the motor through a connector on side A, leaving the opposite face free for coupling devices. The laminated core uses length code D, and frame size 112 sets the outside diameter and bolt circle used across the series. A tachogenerator supplies 3 V/1000 rpm, while incremental tracks or an absolute encoder provide high-resolution position data for the listed feedback arrangement. This combination supports speed monitoring, commutation reference, and accurate position tracking without requiring additional external sensing hardware on the axis. The motor uses standard tacho quality and ED winding code for operation with legacy analog controllers.
