Product Description:

The MAC090C-0-KD-4-C/130-B-0/WI520LV/S011 is an AC servo motor produced by Bosch Rexroth Indramat and supplied within the MAC AC Servo Motors series. The unit is intended for closed-loop motion axes driven by analog amplifiers, where a rotating actuator must deliver consistent velocity and position data to the controller. In automated machinery, it converts electrical commands into mechanical rotation while providing feedback so the drive can correct errors in real time.

Internally, winding code KD sets the electrical resistance and inductance values matched to MAC drives. The motor body seats against a locating shoulder with a centering diameter of 130 mm, allowing accurate alignment in geared or belt-driven stations. Heat generated in the stator is removed solely through natural convection, so no external blower or coolant manifold is necessary. Under rated load, the shaft rotates at 1500 rpm, a speed chosen for applications that need high torque at moderate velocity. An integrated tacho generator outputs 3 V/1000 rpm, giving the drive proportional speed feedback for loop regulation.

The feedback configuration supports tacho feedback and either incremental or absolute encoders; this unit is delivered with an incremental encoder installed on the standard mounting flange to return position data each revolution. Speed sensing accuracy follows the manufacturer’s standard tacho quality grade, suitable for drives that sample velocity at high rates. Because there is no blocking brake, mechanical holding must be supplied by the machine when power is removed. The power leads exit through a keyed connector mounted on side B, simplifying daisy-chain wiring inside compact cabinets. Classified as a motor for analog drives, it integrates with legacy Indramat servo amplifiers that rely on ±10 V command signals rather than fieldbus control.
