Product Description:

The MAC112D-0-ED-4-B/130-A-0 belongs to the MAC AC Servo Motors series from Bosch Rexroth Indramat. It is a motor for analog drives that supplies closed-loop torque and velocity control to positioning tables, gantries, and similar automation axes. By combining field-oriented excitation with an integrated tachometer, it converts command voltages from legacy servo amplifiers into precise mechanical motion without additional signal conditioning.

The centering diameter measures 130 mm, so the housing fits directly into standard recesses on flange-mounted gearboxes and machinery frames. Heat is removed only by natural convection, eliminating the need for external blowers and allowing installation in cabinets where forced air is unavailable. With a nominal shaft speed of 3000 rpm, the rotor can track command changes quickly while staying within the continuous torque range of the ED winding. The internal tachogenerator outputs 3 V/1000 rpm; this proportional voltage is fed back to the analog drive to close the velocity loop. Power conductors reach the stator windings through a connector on side A, keeping cable routing consistent in multi-axis racks where all motors face the same direction.

The frame size is 112, which matches the stator diameter and bolt circle used across other motors in the MAC family. A length code of D increases active iron depth, raising continuous torque without altering the mounting footprint. Winding identification ED indicates copper fill, resistance, and thermal constants, allowing the matching analog drive to use the correct current limits. Position and speed feedback can be provided by the built-in tachometer feedback, incremental encoder, or absolute encoder, depending on controller requirements. Because a blocking brake is not present, any vertical load must be secured by external means when power is removed.
