Product Description:

The MAC071C-0-NS-4-C/095-A-2/WI538LV is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It is supplied for analog drive systems where precise speed and torque regulation are required on production lines, handling stations, and packaging axes. The unit combines a permanent-magnet rotor with integrated tachogenerator and encoder feedback, giving the motion controller real-time velocity and position data. This combination allows closed-loop control to correct speed deviations quickly and maintain stable axis behavior during repeated starts, stops, and load changes across varied duty cycles.

The motor is equipped with a heavy-duty blocking brake that delivers 6.5 Nm of holding torque to secure vertical or suspended loads whenever the drive is disabled. Heat produced by the windings is removed through natural convection, eliminating the need for forced airflow inside compact cabinets. Under rated electrical excitation, the shaft reaches 3000 rpm, a speed that suits medium-inertia machinery driven by belt, gear, or direct couplings. Accurate centering is aided by a 95 mm pilot diameter on the flange, and power conductors enter through a connector on side A so cable routing can follow a uniform layout along multi-axis gantries.

The feedback section generates a tachovoltage of 3 V/1000 rpm and can be paired with an incremental encoder mounted in the standard position for digital position capture. The motor uses stack length C, giving additional active iron compared with shorter versions in the same frame. Frame size 071 matches gearboxes built to the same size code, and winding code NS corresponds to electrical values used to match the motor with a suitable amplifier channel. Tacho quality is standard, and an absolute encoder may be selected when multi-turn position retention is required.
