Product Description:

The MAC071C-0-GS-4-C/095-A-0/WI519LX/S001 is a brushless AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed for analog drives, it converts commanded current from a drive amplifier into controlled torque and speed for coordinated motion axes. In automated packaging, pick-and-place, and material-handling equipment, the motor provides the rotary motion needed to position loads accurately while following dynamic velocity profiles. Its brushless design supports rapid changes in speed without the mechanical wear associated with commutator brushes.

The motor has a frame size of 071, giving it a medium flange that fits common machinery layouts, while length code C provides additional magnetic stack depth for continuous torque. The shaft reaches a nominal speed of 6000 rpm, supporting applications with rapid movement and short operating cycles. A centering shoulder with a diameter of 95 mm locates the housing concentrically on a mounting adapter and helps minimize alignment errors. Heat is removed through natural convection, so the housing requires adequate surrounding airflow rather than an external blower or liquid-cooling circuit. Winding code GS identifies the coil arrangement selected for this speed class and compatible drive operation. The internal feedback system supplies real-time motion data to the analog drive, allowing the controller to correct changes in shaft velocity and position during operation.

Power conductors exit through a connector on side A, allowing the cable to be routed away from nearby axes and moving machine components. Mechanical coupling is provided by a DIN 6885 keyway, which transfers torque positively to a pulley, gearbox, or rigid coupling. The built-in tachometer produces 1.5 V/1000 rpm, giving the controller a proportional signal for closed-loop speed regulation. Incremental encoder mounting is also included, providing a connection point for position feedback when the application requires coordinated axis movement. The motor is supplied without a blocking brake, so an external holding device or drive-generated torque is necessary if a stationary load must remain secured after motion stops.
