Product Description:

The MAC071B-0-PS-4-C/095-A-0/S001 is an AC servo motor manufactured by Bosch Rexroth Indramat and included in the MAC AC Servo Motors series. Intended for analog drive systems, it provides controlled rotary power to indexing tables, pick-and-place axes, and other motion tasks in industrial automation. Its internal tachogenerator or optional incremental or absolute encoder allows the connected controller to monitor speed or position and apply corrective current with minimal delay. This arrangement supports responsive motion on machines that need repeatable acceleration and steady speed regulation during changing load conditions.

This motor reaches a nominal speed of 4000 rpm, giving fast cycle times when paired with suitable gearing. A centering pilot of 95 mm aligns the housing precisely on the mounting surface, which helps keep the motor properly seated during operation. Heat is removed by natural convection, so no external blower or liquid circuit is required. The power leads exit through a connector on side A, which can simplify cable routing where service access is limited to one side of the machine. During operation, the internal tacho produces 1.5 V per 1000 rpm, and that signal helps the analog drive compare commanded speed with actual shaft speed. Standard tacho quality supports stable feedback output, and the feedback arrangement can use tacho feedback alone or a combined encoder signal when finer position data is needed.

A mechanical holding device is not integrated, so the unit operates with no blocking brake, and any application that must lock the shaft when power is removed needs an external restraint. The motor has motor length B and motor size 071, which indicate the stack length, general torque class, and compatible mounting accessories for this frame. The stator uses a PS winding, which corresponds to a fixed combination of resistance, inductance, and current values expected by compatible drive settings. When a brake is not required, the motor can be used without the added inertia and extra wiring associated with an integrated holding mechanism.
