Product Description:

The MAC071B-0-TS-4-C/095-B-0/WI517LV is an AC servo motor produced by Bosch Rexroth Indramat and belongs to the MAC AC Servo Motors series. Designed for analog drives, it converts drive-controller commands into precise rotary motion for positioning or speed-regulated tasks in automated machinery. The combination of a size 071 frame and B-length housing gives the motor a compact form for medium torque requirements in packaging, material-handling, and general assembly lines.

The centering flange measures 95 mm, which aligns the motor on the mounting surface and helps maintain concentricity with the load. Heat is removed solely by natural convection, so airflow around the housing must remain unobstructed to maintain the rated temperature rise. The rotor has a nominal speed of 3000 rpm, which matches the synchronous frequency used by many Bosch Rexroth analog drives for mid-range servo axes. Electrical behavior is set by winding code TS, which determines phase resistance and inductance for use with standard MAC controllers. For velocity feedback, the embedded tacho produces 3 V/1000 rpm, giving the drive a linear voltage signal that scales with shaft speed for closed-loop regulation.

The motor is supplied without a blocking brake, so any holding force must be provided by the transmission or by an external brake when power is off. Feedback is available through the rear-mounted unit, which supports tacho feedback, incremental encoder, or absolute encoder signals, allowing the same frame to serve either speed-only or full position loops. Power conductors exit through a connector on side B, which helps simplify cable routing when side-A access is limited. When the encoder option is selected, position data is delivered by an incremental encoder with standard mounting, ensuring compatibility with drive modules that expect TTL or HTL channels.
