Product Description:

The MAC071C-0-JS-2-C/095-A-0 is an AC servo motor manufactured by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. It is used with analog drives and converts a current command from the amplifier into controlled rotary motion for positioning, speed control, and tension-control tasks. This arrangement allows conventional analog control systems to regulate the axis without requiring a more complex digital motor package. The motor also provides direct speed feedback from the housing, which supports stable operation when the load changes during normal machine cycles.

Its mounting interface uses a centering diameter of 95 mm, which helps align the motor accurately on compatible machine flanges. Heat from the windings is removed by natural convection, so the motor does not need an external fan or liquid cooling circuit. Under rated conditions, the rotor reaches a nominal speed of 2000 rpm, which suits many medium-speed servo applications. The winding code JS identifies the electrical winding used in this motor and matches the operating characteristics expected by the amplifier. For speed regulation, the built-in tachogenerator produces 3 V/1000 rpm, giving the controller a proportional voltage signal that can be used for continuous velocity feedback.

The motor uses frame size 071, which gives it a standardized housing format for machines designed around this platform. Rotational feedback is returned through tacho feedback, so a separate incremental encoder is not required for basic speed monitoring. The motor has no blocking brake, so holding force during a power-off condition must come from the machine or from drive-generated torque where appropriate. Power leads exit through a connector on side A, which can make cable routing easier when the motor is installed near the drive cabinet. The length designation C identifies the housing stack used for this frame size and corresponds to the motor's continuous torque capability.
