Product Description:

The MAC071B-0-FS-3-C/095-A-0/S001 servo motor is produced by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Designed as a motor for analog drives, it converts the current loop issued by classic servo amplifiers into precise shaft motion for packaging lines, printing machinery, and material-handling axes. The device fits midway in the MAC portfolio by combining the FS winding with a B length housing, giving designers a balanced torque-to-mass ratio for continuous positioning tasks in industrial automation.

In mechanical terms, the rotor registers on a 95 mm centering pilot, enabling direct flange alignment to gearboxes or machine plates without additional sleeves. Heat produced by copper loss leaves the frame through Natural convection, so no external blower or liquid circuit is required. Speed regulation tops out at 2000 min⁻¹, matching legacy drive electronics that issue 50 Hz tachometer feedback. The power leads exit through a Connector on side A, simplifying daisy-chain layouts when multiple axes share a cabinet wall. Magnetic density is set by Winding code FS, which defines the coil resistance and inductance used by matching MAC amplifiers.

System integrators must note that the motor ships with no blocking brake, so static holding torque must originate from the drive or a mechanical lock. Feedback is delivered through a 3 V/1000 min⁻¹ tachogenerator mounted on the rear and a mechanical extension that supports tachofeedback and second shaft end for optional encoder coupling. The frame follows the dimensional envelope of Motor size 071, allowing interchange with other MAC units of identical frame while preserving servo rigidity. Alongside its standard tacho quality and the B-length stack, these elements let the axis meet inertia targets without exceeding cabinet thermal limits.
