Product Description:

The MAC112C-0-ED-4-C/130-A-1 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Developed for analog drives, it translates controller commands into precise rotation for automated axes that require stable speed and positional accuracy. Integrated tachometer feedback and an encoder interface give the drive electronics direct velocity and position data, supporting packaging equipment, printing presses, and material-handling machinery that demand consistent motion control. This arrangement lets the connected amplifier react quickly to load changes during indexing, feeding, and continuous-speed operation.

The integrated blocking brake supplies 45 Nm of static holding capacity, so vertical or load-bearing axes remain fixed when power is removed. Heat is dissipated through natural convection, removing the need for external blowers and allowing installation where airflow is limited. Under rated operation, the rotor reaches 3000 rpm, which supports fast axis movement without requiring auxiliary cooling hardware. Accurate mechanical alignment is simplified by a centering flange of 130 mm, which helps the motor seat concentrically against the machine face. Motion feedback is provided through tachometer feedback with an incremental or absolute encoder, enabling either analog velocity control or high-resolution position monitoring depending on the installed drive card.

The motor has a length code of C, which indicates the active stack height and continuous torque class. Its frame size is 112, matching standard MAC mounting patterns used with this housing diameter. Power conductors exit through a connector on side A, which keeps the motor and feedback cables directed to the same side for cleaner routing in compact enclosures. For velocity feedback, the built-in tachogenerator outputs 3 V/1000 rpm, and the analog drive electronics can use that signal directly for closed-loop speed regulation without extra scaling circuits.
