Product Description:

The MAC071A-1-VS-4-C/095-B-0/W1519LV/S001 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Classified as a motor for analog drives, it translates command voltages from an analog amplifier into regulated torque and speed for positioning, indexing, and material-transfer axes. Its electromagnetic design balances dynamic response with steady thermal behavior, giving machine builders a medium-frame option that fits automated tools, handling stations, and light spindles without increasing footprint or mass.

The unit follows size code 071 and presents a centering diameter of 95 mm, allowing direct attachment to IEC-compliant mounting faces. Thermal limits are controlled by axial surface cooling; a frame-mounted blower supplied with AC 230 V directs airflow along the housing to remove heat from the stator laminations. Under nominal excitation, the rotor reaches 6000 min⁻¹, supporting rapid duty cycles in pick-and-place or light machining tasks. The compact A length shortens the magnetic stack, lowering inertia for quick reversals, and the motor is supplied without a blocking brake to avoid residual drag when coasting is required.

The steel shaft is machined with a DIN 6885 keyway for positive torque transfer, while incoming power is routed through a sealed connector on side B that separates it from feedback conductors. Velocity feedback comes from an integral tacho generator that produces 1.5 V/1000 min⁻¹; the signal is graded with standard tacho quality, and the feedback port also accepts incremental or absolute encoders used by the application. Electrical characteristics are fixed by winding code VS, ensuring the paired analog drive can predict current demand and regulate acceleration across the full speed range.
