Product Description:

The MAC071B-0-FS-2-C/095-A-1 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It is categorized as a motor for analog drives and is intended to supply precise speed and torque control to machinery that relies on analog command voltages rather than digital fieldbus signals. In automated handling, packaging, or indexing stations, the unit converts electrical input from a matching servo amplifier into mechanical rotation for axes that require accurate regulation under varying load.

The motor uses frame size 071, giving a compact housing profile that supports installations where space is limited. A centering diameter of 95 mm aligns the flange with gearboxes or mechanical fixtures so that runout is minimized. Under rated conditions, the shaft reaches 2000 rpm, a nominal speed chosen to balance torque production with thermal limits. Coil design is identified by winding code FS; this code indicates phase resistance and inductance so the motor pairs correctly with the analog drive’s current loop. Heat is removed only through natural convection, meaning no external blower or liquid circuit is required and enclosure planning must allow free airflow around the stator.

Holding position during power loss is handled by a blocking brake that delivers 3 Nm of static torque, preventing unintended motion on vertical or loaded axes. Motion feedback is supplied through tacho feedback, giving an analog speed signal that the drive card uses for closed-loop regulation. That signal is proportional to velocity at 3 V/1000 rpm, simplifying calibration because one volt corresponds to roughly 333 revolutions per minute. Power conductors enter through a single connector on side A, so cable routing can follow the machine’s fixed layout while keeping signal and power wiring separated.
