Product Description:

The MAC071B-0-FS-4-C/095-A-1/AM154SG servo motor is produced by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Designed for analog drives, it converts current commands from conventional drive amplifiers into regulated rotary motion for industrial automation axes. The unit suits positioning tables, light machining spindles, and handling devices that need repeatable movement within compact footprints. Integrated tacho or encoder feedback enables the connected controller to monitor shaft velocity and correct deviations in real time. It can be used where analog command structures remain in service and where predictable motor response is important in a compact installation.

A blocking brake is fitted as standard and can hold the shaft with 3 Nm of static torque during power-off conditions. The housing aligns to machine frames through a 95 mm centering diameter, while heat produced in the stator is removed by natural convection, eliminating the need for forced airflow. Under rated excitation, the rotor reaches 2000 rpm, a speed suited to medium-inertia loads and common gearing arrangements in compact motion systems. The electrical winding identified by code FS sets the phase resistance and current limits that the analog amplifier must observe, and length code B indicates the overall body depth for applications with limited installation space.

The tachogenerator outputs 3 V/1000 rpm, and an absolute encoder is available when digital position data is required. This combination gives the connected drive both speed-related feedback and direct position information, depending on the control method used in the machine. Motor size 071 balances torque density against weight for mid-range automation duties, helping the unit fit machines that need responsive motion without a large motor envelope. Power conductors are routed through a locked connector on side A, allowing access from a single face of the cabinet and simplifying cable routing in tight assemblies. Standard tacho quality and optional incremental channels complete the feedback arrangement without separate external transducers.
