Product Description:

The MAC112D-0-FD-4-C/130-A-0/WI520LV is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It is built as a motor for analog drives, so it pairs with legacy motion controllers that output proportional current or voltage commands. In automated machinery, the unit converts those commands into controlled rotary motion, allowing precise positioning or constant-speed tasks without additional mechanical transmissions.

This model is supplied without a blocking brake, so holding torque must be provided externally whenever power is removed. The shaft aligns to machine frames through a centering diameter of 130 mm, which provides an accurate pilot fit for coupling components. Heat is removed only by natural convection; no fan or liquid circuit is included, so installation must permit free airflow around the housing. Under rated excitation, the motor reaches a nominal speed of 2000 rpm, matching drive systems that require moderate dynamics with limited overshoot. The electromagnetic circuit is identified by winding code FD, which indicates the resistance, inductance, and compatible continuous current limits.

The mechanical envelope corresponds to frame size 112, giving a standard shaft height and mounting bolt pattern found in many European machine tools. Power conductors exit through a connector on side A, so cable routing should be planned on that end of the cabinet or motor bed. For velocity feedback, the integral tacho generator produces 3 V/1000 rpm; this voltage is proportional to shaft speed and is adequate for analog drives that monitor tacho signals for closed-loop regulation. Position monitoring relies on an incremental encoder installed with the standard mounting interface, ensuring compatibility with counters or servo controllers that expect incremental pulse trains.
