Product Description:

The MAC112C-0-ED-4-C/130-A-1/WI538LV is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Built as a motor for analog drives, it produces controlled rotary motion for positioning tasks in machine tools, handling modules, and printing equipment. The unit integrates a tachogenerator so that the drive amplifier can monitor speed without an external sensor, which helps simplify feedback wiring in compact automation cabinets. This arrangement also supports stable speed regulation during repeated starts, stops, and low-speed adjustments.

A blocking brake rated at 45 Nm keeps the shaft fixed when power is removed, helping prevent drift on vertical or hold-position axes. Accurate mechanical seating is assisted by a 130 mm centering diameter that aligns the stator with mounting flanges. Heat produced by copper losses is dissipated through natural convection, eliminating the need for forced-air ducting. The rotor can reach a nominal velocity of 3000 rpm, which suits rapid cycle duties in automated equipment. Speed feedback from the internal tachogenerator is proportional to rotation and delivers 3 V/1000 rpm, giving the control loop a linear signal for closed-loop regulation. Power conductors enter through a keyed connector on side A, which helps keep cable routing orderly inside multi-axis enclosures.

Position information is supplied by an incremental encoder mounted in the standard rear housing, supplementing the tachogenerator for finer resolution during low-speed moves. Mechanical depth corresponds to motor length C, providing additional active iron for higher continuous torque than shorter variants. Electrical behavior is set by winding code ED, which gives the motor the resistance and inductance values expected by the matching amplifier. Frame size 112 identifies the stator cross-section used across the MAC series and supports compatibility with standardized flanges, shaft keys, and sealing components. This layout allows the motor to fit established mounting patterns without adding unnecessary installation complexity.
