Product Description:

The MAC071C-0-JS-4-C/095-A-0/DI522LV/S004 is an AC servo motor built by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Delivered as a motor for analog drives, it works with classic velocity and position amplifiers to provide closed-loop motion in industrial equipment. Separate motor feedback channels allow the control system to regulate speed while also tracking position during indexed movement. This layout is well suited to machinery that uses established analog control architecture instead of integrated digital servo electronics. Its feedback arrangement also helps the amplifier correct speed changes under varying load while maintaining consistent axis response.

The electromagnetic package uses the JS winding code, which corresponds to the resistance and inductance values expected by the controller. The motor has a nominal speed of 2000 rpm, which is the rated operating point before field weakening is required. A 95 mm centering diameter helps align the motor with machine flanges, and heat is removed by natural convection cooling, so no external blower or liquid circuit is required. For speed feedback, the internal tacho generator produces 3 V/1000 rpm, giving the analog drive a stable velocity signal during continuous operation and speed corrections.

Position control uses an incremental encoder with shock-damped mounting, which resists vibration while providing accurate pulse feedback for axis control. The dual-loop feedback configuration allows the drive to use the tacho signal for velocity regulation and the encoder signal for position control. The housing uses motor length C in frame size 071, which keeps the package compact while preserving useful torque capacity. Power wiring enters through a connector on side A, which can simplify cable routing in right-hand machine layouts. That layout keeps signal and power connections organized in compact machine spaces. The motor is supplied without a blocking brake, which reduces rotating inertia and leaves holding force to the external system when the axis is stopped.
