Product Description:

The MAC071B-0-PS-3-C/095-B-0/S001 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Supplied as a motor for analog drives, it converts command voltages from a matching amplifier into controlled torque and speed, forming a core element of industrial automation loops. By delivering rapid acceleration, repeatable positioning, and continuous rotation, the device supports packaging machines, pick-and-place axes, and other installations that demand consistent electromechanical performance. It is also suited for applications that require stable speed regulation during repeated start-stop motion.

The motor uses a size 071 frame and a length B housing, giving it a compact profile that eases integration into tight machine chambers. The flange includes a centering shoulder of 95 mm, providing accurate shaft alignment against the driven load. Rated operation occurs at 4000 min⁻¹, which suits medium-inertia applications that still require high cycle rates. Heat produced during duty cycles is removed by natural convection, so no forced-air or liquid cooling is required. All power conductors enter through a connector on side B, permitting cable routing along the back of a cabinet or slide without interfering with the motor face. Internal position sensing uses tacho feedback on a second shaft end to supply the analog drive with real-time velocity data.

The PS winding set establishes the phase resistance, inductance, and obtainable torque when paired with the selected amplifier. The tacho generator supplies 1.5 V per 1000 min⁻¹, giving proportional feedback that supports speed control loops while meeting the motor’s standard tacho quality rating. Because there is no blocking brake, holding torque during power-off must be provided by external mechanics or by the drive. The feedback package and second shaft end also allow the addition of auxiliary sensing or cooling components when the application calls for extra monitoring.
