Product Description:

The MAC071B-0-FS-4-C/095-A-0/WI520LV/S001 is an AC servo motor produced by Bosch Rexroth Indramat and belongs to the MAC AC Servo Motors series. As a motor for analog drives, it delivers closed-loop torque and speed control to position axes, index conveyors, and actuate tooling in industrial automation cells. Its mechanical dimensions follow the 071 frame class, and the device is intended to operate with legacy Rexroth drive amplifiers that rely on tachometer and encoder feedback for velocity regulation.

For mechanical alignment, the housing provides a centering shoulder with a diameter of 95 mm, allowing direct location into gearheads or machine frames. Heat is removed solely by natural convection, so airflow around the stator must remain unobstructed when the motor operates near its rated load. The stator coils use winding code FS, which indicates electrical values matched to MAC analog amplifiers. Under nominal conditions, the rotor reaches 2000 rpm, a speed suited to positioning loads quickly while remaining within tachometer bandwidth. The internal tacho generator delivers 3 V/1000 rpm, supplying the drive electronics with a proportional velocity signal for closed-loop analog regulation.

The shaft end uses a DIN 6885 keyway for coupling sprockets or pulleys without external machining. Power conductors are routed through a plug on side A, which can simplify cable routing where the motor faces the drive line. Overall stack height is identified by length code B, balancing inertia and continuous torque within the 071 frame. Position feedback is provided through incremental encoder signals that share the tachometer channel, and the motor has a Standard accuracy class. Because the design is supplied without a blocking brake, static loads must be held by drive torque or an external clamp.
