Product Description:

The MAC071C-0-US-4-C/095-B-2/W1538LV is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed as a motor for analog drives, it delivers precise torque and velocity control to axes that depend on external drive amplifiers for closed-loop positioning. The unit targets general industrial automation, supplying electromechanical power where coordinated motion, repeatable speed profiles, and high cycle counts are required on packaging lines, machine tools, and material-handling equipment.

Mechanical integration is supported by a heavy-duty blocking brake that provides up to 6.5 Nm of holding torque, allowing the shaft to stay locked when the drive is disabled. Accurate concentric alignment is achieved with a centering flange diameter of 95 mm, while heat is removed only through natural convection, eliminating the need for forced air or liquid circuits. Power conductors are routed through a connector on side B, and this orientation simplifies cabinet wiring when the motor is mounted with the shaft facing the operator. This arrangement is useful on axes that require holding torque during stops and orderly cable routing.

During operation, the rotor reaches a nominal speed of 2000 rpm, and the integrated tachogenerator outputs 3 V/1000 rpm so the external drive amplifier can monitor actual speed without a separate encoder card. The windings follow the US code, matching resistance and inductance to compatible drives that supply the correct current for this frame. With a frame designation of 071 and the length group C, the motor offers a compact envelope with enough active iron for moderate continuous duty. Standard tacho quality supports stable speed feedback for analog drive operation and helps the amplifier track actual motor speed during routine axis motion.
