Product Description:

The MAC071B-0-FS-3-C/095-B-1/S001 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It is intended for analog drive systems where precise speed regulation and positioning are required in automated machinery, production cells, transfer units, and feed mechanisms. By combining a medium frame size with internal tacho feedback, the motor supplies continuous closed-loop information to its drive controller. This feedback arrangement helps the paired amplifier correct speed deviations during changing loads and supports integration into legacy or retrofit automation systems.

This model includes a standard blocking brake that can hold up to 3 Nm of torque when the shaft is at rest, providing static load holding during power-off conditions. A centering diameter of 95 mm aligns the flange with gearboxes or mounting plates to help maintain concentricity and minimize radial runout. Cooling relies on natural convection, so airflow around the housing is sufficient without external blowers. The rated mechanical speed is 2000 rpm, matching many indexing tables and feed axes that operate below synchronous speed. For velocity feedback, the built-in tacho generator outputs 3 V/1000 rpm, delivering a linear signal that the analog controller can interpret directly. Power conductors terminate through a connector on side B, which can simplify cable routing when multiple motors are installed side by side.

Frame designation 071 indicates the stator size and balances torque density with manageable mass, while motor length code B keeps the axial dimension relatively short for compact machine spaces. Electrical characteristics are set by winding code FS, which gives the resistance and inductance profile expected by matching legacy drives. The rotor includes a second shaft end, which can be used for auxiliary couplings or additional feedback devices. That layout can also support applications that need an extra mechanical connection without changing the main flange mounting.
