Product Description:

The MAC090C-0-KD-4-C/110 is an AC servo motor manufactured by Bosch Rexroth Indramat and belongs to the MAC AC Servo Motors series. Within automated machinery, it functions as a rotary actuator that works with analog drive controllers to deliver closed-loop speed and torque for positioning and process axes. Its operating concept suits equipment that requires controlled rotary motion with stable response under changing load.

This model is built on a mechanical frame that centers in the machine housing through a 110 mm pilot diameter, which helps maintain repeatable shaft alignment. Heat is removed by natural convection, so installation must leave free airflow surfaces rather than rely on forced fans. Because the housing has no auxiliary blower, ambient temperature must remain within the approved operating range. For velocity feedback, the motor can be ordered with a dedicated tacho feedback generator or with an incremental or absolute encoder; both options provide the analog drive with real-time speed signals. Rated operating speed is 1500 rpm, which suits common spindle or conveyor requirements and keeps electrical frequency within standard inverter ranges. The internal DC tacho produces 3 V/1000 rpm, allowing the controller to scale speed proportionally without external dividers. This linear signal simplifies direct monitoring with standard ±10 V analog cards.

The electrical behavior is set by the KD winding, which establishes the phase resistance and inductance needed for predictable torque across the working range. Signal precision is aided by standard tacho quality, which keeps ripple within limits for steady low-speed control. Supplied as a motor for analog drives, the unit pairs directly with legacy Indramat TDM and KDS amplifiers that use compatible speed feedback. This arrangement supports continued use in installed systems where analog command handling remains in service.
