Product Description:

Bosch Rexroth Indramat manufactures the MAC112D-0-ED-4-C/130-A-0-W1520LV/S005, a member of the MAC AC Servo Motors series. It is specified as a motor for analog drives. The unit receives current-controlled commands from legacy servo amplifiers and turns them into regulated mechanical motion for industrial positioning and velocity loops in material handling and packaging equipment. That arrangement supports older control platforms that rely on analog command signals rather than digital communication.

The motor has a nominal shaft speed of 3000 rpm, which provides a stable operating point for analog servo systems. Thermal balance is maintained by natural convection, so no external blower or liquid circuit is required. The machining interface uses a 130 mm centering diameter that aligns the flange to gearboxes or mounting plates. The ED winding code indicates the phase resistance, inductance, and permissible current for the 112 frame. Power conductors enter through a connector on side A, keeping the cable bundle on the same face as the amplifier cabinet. A blocking brake is not present, so static holding torque must come from the drive or external clamps.

The resolver channel is supplemented by a tachogenerator that delivers 3 V/1000 rpm, giving current-controlled amplifiers proportional speed feedback without digital scaling. Shaft torque is transmitted through a DIN 6885 keyway, allowing standard keyed couplings while helping prevent slip under cyclic load. The D construction code indicates the application length, and the frame follows the 112 size convention used for this motor platform. Standard tacho quality supports repeatable voltage symmetry, and the selectable incremental or absolute tacho feedback encoder supports use with closed-loop velocity loops or position modules without extra transducers.
