Product Description:

The MAC112D-0-ED-2-C/130-A-0/S05 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed as a motor for analog drives, it converts continuous voltage or current commands from drive electronics into precise rotary motion. Within industrial automation systems, the unit provides closed-loop position or speed control for tasks such as indexing tables, packaging axes, and material-handling gantries where accurate and repeatable motion is required. Its mechanical interface and feedback arrangement follow platform standards so that it integrates cleanly with legacy drive controllers on many factory floors.

The motor uses a centering diameter of 130 mm, which aligns the housing to gearboxes or machine plates without additional bushings. Cooling relies on natural convection, and the ribbed frame dissipates heat to ambient air without requiring fans or coolant circuits. Under rated excitation, the rotor reaches 3000 rpm, matching the dynamic range expected by many analog velocity loops. Power is delivered through a rugged connector on side A, which supports straightforward cable routing in compatible installations. For velocity feedback, a permanent-magnet tacho generator delivers 3 V/1000 rpm, giving the drive a proportional signal for current regulation.

The feedback channel uses tacho feedback, providing a simple analog path that keeps loop delay low in retrofit applications. Within the series, frame code 112 indicates the stator diameter, while length code D indicates an extended magnetic stack for higher continuous torque without changing the mounting face. Winding code ED identifies the electrical winding used with compatible drive amplifiers. A blocking brake is not present, so vertical axes must rely on external holding devices. The tacho generator is built to standard quality tolerance for consistent calibration throughout its service life.
