Product Description:

The MAC071B-0-FS-4-C/095-B-0 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed for analog drives, it converts controller commands into controlled rotation for positioning and speed regulation in automated machinery. By using electronic feedback and matched windings, the unit supports closed-loop motion in packaging lines, printing equipment, transfer axes, and other general factory automation tasks where stable speed, repeatable positioning, and smooth response to changing loads are required.

The winding code FS indicates electrical characteristics suited for compatible drive amplifiers that require moderate current while maintaining responsive acceleration and stable speed control. Under rated conditions, the rotor reaches a nominal speed of 2000 rpm, which sets the mechanical output frequency and the back EMF used for velocity regulation. Heat is removed through natural convection, so the housing needs unobstructed surrounding airflow during operation and does not rely on external fans. A centering diameter of 95 mm helps align the motor accurately on machine flanges or gearbox faces. The motor is supplied without a blocking brake, so holding torque must be provided by external means when power is removed.

Feedback is available through tacho feedback with an incremental or absolute encoder, allowing the drive to process position and speed information from the integrated interface. The motor has motor size 071 and motor length B, which help determine the space needed for installation and the coupling arrangement around the shaft end. Power conductors exit through a connector on side B, which can simplify cable routing when the motor is mounted close to a machine wall or other equipment. The embedded tacho generator supplies 3 V/1000 rpm as an analog signal proportional to shaft rotation for continuous speed monitoring by the drive electronics.
