Product Description:

The MAC112B-0-LD-4-C/130-A-1/DJ568LX is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Classified as a motor for analog drives, it converts continuous control voltages from a drive amplifier into regulated shaft rotation for positioning or speed-regulated tasks in automated equipment. By integrating mechanical power generation with electrical feedback devices, the unit provides a closed-loop actuator for conveyors, machine-tool axes, and handling systems where reliable torque and velocity control are required.

A standard blocking brake supplies 45 Nm of holding torque, preventing load drift whenever the drive is disabled. The mounting pilot has a diameter of 130 mm, which centers the housing precisely on a machine flange and maintains alignment under dynamic loads. Heat is removed by natural convection, so no external blower or liquid circuit is needed, but free air space around the frame must be maintained. The rotor achieves a nominal speed of 2000 rpm, providing a balance between torque density and attainable linear feed rates. Power conductors terminate through a connector on side A, so the motor cable can be routed in the same direction as adjacent feedback lines, reducing loop area and electromagnetic interference. Tacho feedback, delivered as either incremental pulses or an absolute position word, supports velocity or position loops without additional sensors.

The electromagnetic circuit follows winding code LD, a selection that matches drive modules capable of higher current at moderate voltage. Frame designation 112 sets the stator diameter, while motor length code B extends the stack for increased continuous torque without forced cooling. The built-in tachogenerator outputs 3 V/1000 rpm, a level suited to analog velocity regulators, and it has Standard tacho quality for predictable linearity across the speed range.
