Product Description:

The MAC112D-0-ED-4-C/130-A-2/WI574LX/S018 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Intended for analog drive architectures, it converts command voltages into controlled shaft rotation for positioning, material handling, and metal-cutting axes across automated machinery. Integrated motor feedback gives the controller a continuous view of shaft motion, which helps the drive correct deviations caused by changing load conditions. Because the feedback devices are built into the motor, the axis can support closed-loop operation without separate external measuring hardware.

A built-in heavy-duty blocking brake keeps the shaft fixed after power removal, and its holding torque reaches 60 Nm, making it suitable for vertical or suspended loads. This brake also helps prevent unwanted drift when the machine is stopped. Mounting alignment is aided by a 130 mm centering diameter that fits common machine interfaces. Heat is dissipated through natural convection, so the motor operates without an external blower or liquid circuit. The rotor has a nominal speed of 3000 rpm, giving the drive a broad working range for continuous motion and rapid positioning cycles.

Power leads exit through a connector on side A, which helps keep cable routing on one face of the machine. A built-in tachogenerator delivers 3 V/1000 rpm for speed regulation, and an incremental encoder with standard mounting provides position feedback to the controller. The encoder signal allows the control system to track shaft movement during indexing and speed changes. The ED winding code identifies the electrical winding used in this variant, and the motor uses frame size 112 with length code D for its mechanical envelope. This arrangement supports analog control systems that need steady speed feedback and repeatable position information during axis motion.
