Product Description:

The MAC112C-0-ED-4-C/130-A-1/WI520LX/SO5 is a servo motor built by Bosch Rexroth Indramat for the MAC AC Servo Motors series. As a drive element for analog motion controllers, it delivers commanded torque and speed to automated axes in packaging machines, printing lines, and material-handling systems. Its electromagnetic design supports precise closed-loop positioning where stable rotation, quick response, continuous operation, and a compact installation depth are required. Integrated speed and position feedback allows the connected controller to correct motion in response to changing commands and loads.

An integrated blocking brake rated at 45 Nm prevents shaft movement when the drive is disabled, allowing vertical or indexing loads to hold position without external clamps. Precise mounting is aided by a centering pilot of 130 mm, which aligns the flange with gearboxes and machine plates. Heat generated in the stator is removed solely by natural convection, eliminating the need for forced air or liquid cooling circuits. The rotor has a rated speed of 3000 rpm, providing the velocity range needed for many automated positioning and material-handling tasks. Power conductors enter through a connector on side A, simplifying cable routing along one face of the machine. The frame code 112 indicates the stator size and its compatibility with matching mounting components. The alphabetic length index C indicates the active stack depth used for continuous motor output.

The electrical windings use code ED, which identifies resistance and inductance values matched to compatible Indramat analog amplifiers. Position data are returned by an incremental encoder mounted in the standard feedback housing, allowing the controller to track shaft movement during operation. The encoder operates alongside an internal tacho generator that produces 3 V/1000 rpm, providing a proportional speed signal for the velocity control loop. The feedback package uses the standard accuracy grade for general-purpose automation tasks. This arrangement gives the analog controller separate position and velocity information without requiring an external shaft-mounted feedback device.
