Product Description:

The MAC090C-0-KD-4-C/110-B-1/AM164SG is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Classified as a motor for analog drives, it receives proportional command voltages from a drive card and delivers controlled shaft torque and speed to automated stations. The housing, rotor assembly, and feedback devices work together to support closed-loop positioning tasks such as indexing, tension control, and intermediate conveying within industrial automation cells. Its standardized frame dimensions support integration with compatible mounting and coupling arrangements used across the series.

Mechanical alignment is aided by a centering diameter of 110 mm, which gives repeatable seating in pilot bores. The KD winding code identifies the stator impedance and matches the motor to analog drive modules that supply its rated current. Under nominal excitation, the shaft maintains 1500 rpm, providing a predictable base speed for gearing calculations. Heat is dissipated by natural convection, so the installation must allow free ambient air circulation. When motion must stop quickly or remain fixed during downtime, a standard blocking brake engages the rotor without external actuators.

Electrical terminations use a connector on side B, keeping power cables away from the driven load and simplifying strain-relief routing. Speed feedback is generated by the built-in tacho generator, which outputs 3 V/1000 rpm; this linear signal supports analog velocity loops. For position monitoring, the motor uses tachofeedback with an incremental or absolute encoder, allowing the drive to track shaft movement with feedback suited to the application. The primary feedback arrangement is listed as standard tacho quality, which indicates the selected tachometer execution for this motor configuration.
