Product Description:

The MAC112C-0-ED-4-C/130-A-0/WI520/S05 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed for analog drives, it converts controlled drive current into precise shaft torque for industrial positioning and velocity-control loops. The motor works with compatible analog velocity or torque controllers to provide closed-loop motion. This arrangement supports repeatable speed regulation in conveyors, tool changers, assembly axes, and other automated machinery.

A centering diameter of 130 mm aligns the motor housing accurately with mating flanges and connected equipment. The motor reaches a rated speed of 3000 rpm, allowing it to drive suitable gearboxes or belt transmissions used in machine tools and production equipment. Heat generated in the stator is removed through natural convection, so the installation does not require an external blower or liquid-cooling circuit. Winding code ED identifies the electrical characteristics used by compatible MAC analog drives. The rotor has a length index of C, providing a longer magnetic path and greater continuous torque than a shorter rotor while retaining a practical mounting envelope.

The motor has a frame size of 112, which establishes the stator diameter and mounting pattern associated with this model. Its tachogenerator produces 3 V/1000 rpm and has standard tachometer quality, supplying velocity feedback to compatible legacy controllers. The motor has no blocking brake, so an external holding method is necessary when an unpowered axis must support a vertical or suspended load. Power conductors leave through a connector on side A, allowing cable routing toward equipment installed on that side of the machine. Position feedback is supplied by a standard-mounted incremental encoder, which gives the controller the shaft-position information needed for accurate motion regulation. The combined tachometer and encoder arrangement allows the drive system to monitor both velocity and position without requiring a separate feedback device outside the motor housing.
