Product Description:

The MAC071C-0-JS-4-C/095-B-0/WI520LV/S001 is an AC servo motor manufactured by Bosch Rexroth Indramat and assigned to the MAC AC Servo Motors series. Classified as a motor for analog drives, this size 071 unit converts proportional current commands into rotary motion for axes that rely on analog amplifiers rather than digital fieldbus drives. It provides continuous speed and torque regulation for positioning tables, pick-and-place modules, and conveyor sections that require stable feedback in a compact motor package. Because the control concept is analog, the motor can work with established amplifier platforms that use current commands and external feedback channels instead of onboard digital motion processing.

A centering pilot of 95 mm helps the motor seat accurately in housings or gearboxes. Heat is removed by natural convection, so no auxiliary fan is required when surrounding airflow is sufficient for rated dissipation. The windings carry code JS and support continuous operation at 2000 rpm, which suits analog velocity loops that depend on predictable base speed. The motor is supplied without a blocking brake, so any load that must remain fixed during power loss needs an external holding method. A built-in tachogenerator produces 3 V/1000 rpm, and its signal can be used directly by analog controllers for speed feedback. Motor length code C provides the active iron stack used for this output range.

The output shaft uses a DIN 6885 keyway to transmit torque while maintaining radial alignment with the driven load. Power cabling is routed through a connector on side B, which can simplify wiring when access to the rear of the machine is limited. For position loops, the integrated incremental encoder with standard mounting adds position feedback that complements the tachogenerator. This arrangement allows simultaneous speed and position monitoring on analog servo axes. It also supports legacy or retrofit analog systems that separate velocity regulation from axis positioning while keeping the motor package compact.
