Product Description:
The MAC071B-0-TS-3-C 095-B-2 is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It is intended for analog drive systems where precise speed and torque regulation are required for automated tooling, positioning tables, and conveyor axes. The unit converts electrical input from a drive controller into mechanical rotation, allowing closed-loop motion control in industrial automation. Its construction combines permanent-magnet excitation with rotor feedback so commanded values can be matched quickly under varying load conditions.
A key mechanical feature is the heavy-duty blocking brake, which delivers a holding torque of 6.5 Nm. This brake locks the shaft whenever the drive is disabled, helping prevent vertical or load-bearing axes from drifting. Thermal management relies on natural convection, so heat leaves the housing through surface radiation and ambient airflow without fans or liquid circuits. The centering diameter of 95 mm aligns the motor accurately on the machine frame and helps limit runout. Under rated excitation, the rotor reaches 3000 rpm, matching many analog control loops used in industrial motion systems.
Electrical interfaces are arranged with the power cable exiting on connector on side B, which simplifies routing in machines that place the second shaft end outward for encoder coupling. Motion feedback is provided by a tachogenerator and a second shaft end, and the tachogenerator produces a proportional signal of 3 V/1000 rpm for repeatable velocity measurement. The electromagnetic winding code TS indicates the resistance and inductance values used with analog current controllers. The frame size code 071 standardizes the flange dimensions used across the series. The motor operates without auxiliary cooling devices, which keeps the installation layout straightforward.
