Product Description:

The MAC112C-0-KD-4-C/130-A-0/WI520LV is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It pairs with the manufacturer's analog drive amplifiers to provide closed-loop torque and speed control on automated production lines, pick-and-place gantries, and material-handling axes. By converting command voltages from the drive into rotary motion with precise feedback, the unit serves as the electromechanical link between electronic controllers and mechanical loads in industrial automation.

The motor uses winding code KD, which indicates the winding and magnetic-circuit combination used for this version. Under rated excitation, the shaft reaches 1500 min⁻¹, a speed that balances dynamic response with torque density for medium-inertia loads. Thermal energy created in the stator is dispersed by natural convection, so installation requires unobstructed airflow rather than forced cooling. Power is supplied through a single connector on side A, which keeps the cable exit on the same face as many drive layouts and helps limit bend stress inside the cabinet. A centering diameter of 130 mm guides the pilot fit into the machine flange to support accurate alignment. Tachometer feedback is available with incremental or absolute encoder arrangements, and this unit is equipped with the standard factory-mounted incremental encoder for the series.

Because the motor includes no blocking brake, applications that need static holding must use an external brake or maintained drive current. Frame size code 112 identifies the stator outer dimension used for this housing. Length code C indicates an extended lamination stack that supports higher continuous output than shorter versions in the same frame. The integrated tachogenerator supplies 3 V/1000 min⁻¹, giving the analog controller a linear speed-proportional signal for regulation.
