Product Description:

The MAC090C-0-GD-4-C/110-B-0/WI520LV/S001 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It is engineered to supply controlled torque and speed to machinery that depends on analog drive amplifiers for closed-loop regulation. By integrating a permanent-magnet rotor with electronic feedback hardware, the unit delivers precise positioning, velocity control, and coordinated motion in packaging equipment, machine tools, and material-handling systems.

Its mechanical interface includes a centering flange diameter of 110 mm, which aligns the stator housing accurately against gearboxes or machine frames. Thermal energy is released through natural convection, so the motor can be installed without external blowers when ambient airflow is sufficient. The motor is supplied without a blocking brake, so vertical axes may require an external holding device when power is removed. Electrical power reaches the stator windings through a connector on side B, which can simplify cable routing when the rear of the motor faces the control cabinet. Internally, the stator uses winding code GD, which corresponds to electrical values matched to the current range of the associated MAC controller.

Signal feedback is delivered through a combination of tacho and encoder devices. The motor is categorized as a motor for analog drives, so its speed loop closes inside an external controller that interprets the tacho voltage. For higher resolution, the secondary channel provides tacho feedback with an incremental or absolute encoder signal, supporting both speed and position loops. The position channel uses an incremental encoder with standard mounting, which supports installation in units that share the same mechanical envelope. Because the rotary tacho is built to standard tacho quality, its voltage ripple remains within the limits required for stable analog velocity regulation.
