Product Description:

The MAC112D-2-ED-4C/130-A-0/DI520/S05 is an AC servo motor built by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It converts controlled current from a compatible drive amplifier into precise torque and speed, allowing automated axes to start, stop, and reverse with repeatable motion. This operating role makes the motor suitable for assembly lines, packaging equipment, and material-handling stations where axis timing must remain consistent from cycle to cycle. Its rotary output supports both positioning moves and steady-speed operation, so the same unit can serve transfer, indexing, or feed applications. The motor also provides the electromechanical link between the drive and the machine load, translating electrical commands into usable shaft motion.

Cooling air is supplied by a blower powered from AC 115 V, and the motor uses axial surface cooling to carry heat away from the stator housing during continuous operation. Forced airflow helps stabilize internal temperature when the axis runs for long periods or sees repeated acceleration and deceleration. The motor has frame code 112, and length code D indicates an extended active section that supports higher continuous torque within the same mounting pattern. This arrangement allows the machine layout to retain the same general installation geometry while gaining a longer active motor section. Winding code ED sets the electrical characteristics expected by compatible Indramat power modules, helping the motor operate within the intended current range.

The motor has a nominal speed of 3000 rpm, which gives the drive a familiar operating range for positioning and speed-control duties. Feedback is provided by an incremental or absolute encoder with tacho feedback, so the controller can receive both position information and speed-related signals from the integrated sensor package. This feedback arrangement supports both established control schemes and installations that need direct position data at the motor. It is specified as a motor for analog drives, allowing use with voltage-controlled amplifiers without additional signal-conversion hardware. This configuration suits applications that need dependable velocity response, repeatable positioning, and straightforward feedback integration.
