Product Description:

The MAC117B-0-KS-4-C/130 is a brushless AC servo motor built by Bosch Rexroth Indramat and assigned to the MAC AC Servo Motors series. The unit is used on drive axes that need precise torque and speed control from an external servo amplifier. Within an automation cell, it converts commanded current into proportional mechanical rotation, allowing synchronized motion of gantries, tool changers, or material-handling stages while maintaining tight positional repeatability under cyclic loading and low electrical noise during normal duty cycles.

Mechanically, the motor body aligns to driven equipment by means of a centering pilot with a diameter of 130 mm, so case runout is minimized when the flange is clamped to a machine frame. The active stator cross-section is referenced by size code 117, while the overall stack length is indicated by frame designation B. Stator conductors follow winding code KS, a pattern that sets phase resistance and inductance for compatibility with the output voltage of the associated analog drive, and heat generated in the windings is removed through natural convection, which allows installation without external blowers when ambient airflow around the housing remains unobstructed.

Position and velocity signals are returned to the controller through a feedback interface that supports either an incremental encoder or an absolute encoder in combination with an integrated tacho generator. This configuration matches analog servo loops in which commutation is derived from rotor speed and direction. The motor is classified as a motor for analog drives, and speed tracking accuracy is aided by a tacho that meets standard quality grading, providing consistent voltage in proportion to revolutions per minute so the drive can maintain the command reference without overshoot.
