Product Description:

The MAC071A-0-ES-2-C/095-B-1/S001 is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed for analog drives, it turns proportional voltage commands into controlled shaft rotation for positioning and feed duties across automated lines. A standard blocking brake is built in so the shaft can be arrested whenever control power is removed, safeguarding vertical axes and simplifying safety interlocks on established machinery.

Its nominal shaft speed of 4000 rpm marks the operating point where electrical frequency and mechanical output remain synchronized, making the unit appropriate for medium-speed tooling, indexing stations, and light conveyor segments. A static holding capacity of 3 Nm prevents shaft creep during dwell periods and keeps fixtures steady during tool changes. Accurate mechanical seating is assisted by the 95 mm centering diameter that matches common servo flanges. Heat generated in the stator is released through natural convection, so installation must leave clearance for ambient airflow rather than forced ventilation. Rotor velocity is sensed through tacho feedback; this analog signal supplies real-time speed data to legacy controllers that regulate drive voltage in closed loop.

The embedded tacho generator outputs 1.5 V/1000 rpm, giving the control card a linear reference for overspeed protection and fine trimming at low revolutions. Power conductors terminate on a removable plug identified as a connector on side B, which streamlines wiring when the opposite face is inaccessible. The winding code is ES; this selection balances resistance and inductance to minimize overheating during continuous operation. The frame is cataloged as size 071 with length code A, providing a compact rotor stack that reduces moment of inertia while still meeting the speed range demanded by pick-and-place arms or small gantry axes. Tacho quality is standard, ensuring repeatable feedback without the tighter calibration used for high-precision finishing equipment.
