Product Description:

The MAC071C-0-GS-4-C/095-A-0/WJ522LX is an AC servo motor produced by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. This model is supplied for analog drive controllers, where it converts regulated current into repeatable torque and speed for indexing tables, pick-and-place gantries, and other motion axes. By integrating tachometer feedback and encoder options, the motor supports closed-loop regulation without additional external sensing hardware.

The stator and mounting interface use a centering diameter of 95 mm, so the motor seats directly into standard pilot holes and maintains axial alignment with minimal shimming. Heat generated by copper losses is removed through natural convection, so no fan or liquid circuit is required and the unit should be installed where ambient airflow is not blocked. Under rated supply, the rotor can reach a nominal speed of 6000 rpm, which suits belt-driven or direct-coupled mechanisms on analog drives. Internal wiring uses winding code GS, which indicates the voltage constant and impedance used with the matching power stage. For cabling convenience, the power terminals are arranged on a connector on side A, allowing the harness to exit toward the drive cabinet without sharp bends.

The motor uses length code C and frame size 071, giving a compact profile that balances torque output and inertia for rapid acceleration in analog control loops. Integrated tachometer circuitry produces 1.5 V/1000 rpm, supplying a proportional speed signal that the drive uses for continuous velocity correction. The motor is supplied with no blocking brake, so stationary holding torque must be provided by the drive or an external lock. Standard tacho quality and selectable incremental or absolute encoder feedback complete the configuration for applications that cannot accommodate digital SERCOS or fieldbus interfaces.
