Product Description:

The MAC071B-0-KS-3-C/095-A-1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Classified as a motor for analog drives, it converts electrical power into controlled rotary motion for packaging lines, pick-and-place modules, and other industrial axes that rely on analog amplifiers for regulation. A permanently excited rotor enables rapid torque changes, and an integrated blocking brake secures the shaft when power is removed so vertical or suspended loads stay in position during power loss or emergency stops.

The unit relies on natural convection, so its housing fins dissipate heat without fans or liquid circuits. Under rated conditions, the shaft reaches 6000 rpm, a speed suitable for indexing tables while remaining within the limits of the motor frame. The blocking brake supplies 3 Nm of static holding torque, which is suitable for moderate inertial loads on vertical axes. Accurate alignment with gearboxes or bearing blocks is provided by a 95 mm centering diameter that positions the flange concentrically. Position feedback comes from an encoder package configured with tacho feedback and a second shaft end, allowing legacy velocity loops to receive real-time speed directly from the rear tachogenerator.

The tacho generator outputs 1.5 V/1000 rpm, giving drive cards a linear signal that simplifies velocity calibration. Frame code 071 indicates the stator diameter and mounting pattern, while the compact length coded B keeps overall depth low for machines with limited space. Copper distribution follows winding code KS, balancing continuous current capability with thermal rise when powered from standard MAC converters. Input power reaches the stator through a single connector on side A, which routes cabling toward the drive end and leaves the opposite face clear for coupling hardware. This arrangement also helps reduce bending strain during installation.
