Product Description:

The MAC112D-0-ED-4-C/130-B-0/WI520LX/S005 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed for analog drives, it supplies finely regulated torque to conveyors, gantry axes, and spindle assemblies in automated lines. The motor works with amplifier cards that interpret tachometer and encoder feedback, enabling closed-loop speed control in installations that rely on voltage-controlled stages rather than modern networked drives. This arrangement also suits retrofit machinery that continues to use established analog motion hardware.

The mechanical interface uses a centering diameter of 130 mm, allowing rigid alignment to the machine housing. Heat is removed through natural convection, so no external blower or liquid circuit is required. Under rated excitation, the rotor reaches 3000 rpm, a speed that matches typical ball-screw and belt transmissions. Winding code ED identifies the electrical winding arrangement used for this motor. Power conductors exit through a connector on side B, which keeps the cable run away from the load side and simplifies access to the connection point. This layout supports straightforward integration in enclosed machine frames where cable routing space can be limited.

Axis coupling uses a DIN 6885 keyway on the shaft, giving positive torque transfer without additional hub machining. Position feedback is handled by an incremental encoder with standard mounting, and the winding also includes tachofeedback for analog speed regulation. The motor has no holding brake, so any static load must be secured by the drive or by external clamps. Speed information for the control loop is provided by the tachometer, which generates 3 V/1000 rpm to match the input sensitivity of legacy analog regulators. This combination of encoder and tachometer feedback supports stable operation in systems that separate position and speed evaluation.
