Product Description:

The MAC071A-0-0S-4-0/095-B-0/WI524LX is a servo motor that belongs to the MAC AC Servo Motors series from Bosch Rexroth Indramat. Built as a motor for analog drives, it converts drive current into precise shaft rotation for position and speed control tasks in industrial automation. This electromechanical unit is intended for integration with legacy or stand-alone analog amplifiers where real-time torque response and a compact envelope are required. This format supports applications that use external analog control loops rather than integrated digital motion control. Its mechanical interface follows standardized flange dimensions so the shaft can align with gearboxes, ball screws, or timing pulleys used on machine axes.

The compact 071 frame size sets the cross-section of the stator housing and allows direct mounting to machinery built for medium torque levels. A centering diameter of 95 mm positions the flange precisely on the machine face and keeps the rotor concentric with coupled loads. Thermal energy is removed by natural convection, so no external fan or liquid loop is needed during continuous duty. All three power phases are delivered through a single connector on side B, keeping the cable run clear of the driven shaft. Because there is no blocking brake, the application must rely on drive torque or an independent clamp to hold the axis when power is removed.

Speed feedback is produced by integrated tacho feedback, giving the analog amplifier a proportional voltage for closed-loop velocity regulation. Position information is provided by an incremental encoder installed in the standard mount, enabling fine reference marks for homing or electronic gearing. The motor length A shortens the package, which is useful when mechanical space is limited between adjacent axes. The connector layout and feedback arrangement match the MAC AC Servo Motors platform, allowing the motor to fit systems already arranged for this series.
