Product Description:

The MAC092B-0-QD-4-C/095-B-1/WI524LV is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. As a motor for analog drives, it converts drive-controller current commands into precise rotary motion for machinery axes, presses, and material-handling stations where closed-loop positioning accuracy is required in automated production equipment. Its operating concept supports stable speed regulation and repeatable movement during continuous machine cycles, even when load conditions change during acceleration and deceleration. The motor is intended for systems that use external drive electronics and depend on motor feedback to maintain commanded speed and position across start, stop, and dwell phases.

To align the motor shaft concentric with a gearbox or load, the front flange provides a centering diameter of 95 mm. This mounting feature helps maintain accurate mechanical alignment and reduces coupling stress during installation. Heat generated in the stator is removed by natural convection, which eliminates the need for an external blower and keeps the cooling arrangement simple. For velocity and position control, the feedback system combines tachofeedback with an incremental or absolute encoder, so the drive can receive both speed voltage and position data from one package. Power conductors enter through a connector on side B, which helps keep cable routing separated from the feedback connection.

A standard blocking brake is integrated to hold the shaft when system power is removed, which helps prevent load drift on vertical or indexing axes. This brake is useful when the axis must remain stationary between motion segments. For position measurement, the secondary channel uses an incremental encoder with standard mounting, which supports direct connection to compatible feedback hardware without requiring a special adapter arrangement. The motor has a standard tacho quality rating, and the tachogenerator outputs 7.5 V per 1000 rpm for linear speed feedback to the connected controller. Winding code QD identifies the electrical setup used for this motor type and helps match the motor to suitable drive parameters.
