Product Description:

The MAC090C-0-GD-4-C/110-B-1/WI524LX/S005 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed for older voltage-command servo systems, it converts command voltages from legacy controllers into controlled rotary motion for machine axes, conveyors, or tooling spindles in industrial automation lines. The unit sits between the drive electronics and the mechanical load, supplying torque and speed feedback so the analog loop can hold position or follow a velocity profile.

Mechanically, the motor centers on a 110 mm pilot diameter that aligns it precisely against mounting flanges. This centering fit helps keep shaft alignment stable when the motor is bolted to a mating machine surface. Heat is removed by natural convection, so it can operate without an external blower when ambient airflow is adequate. Electrical feedback includes tacho and encoder feedback, giving the drive the speed information needed for closed-loop control. The output shaft incorporates a shaft seal to limit dust or oil ingress at the bearing interface. For wiring, power conductors connect through a connector on side B, which supports cable routing along the non-drive end of the machine.

In drive configuration terms, the motor is classified as a motor for analog drives, meaning its built-in feedback signals are intended for voltage-controlled amplifiers rather than digital fieldbus devices. Position reference comes from an incremental encoder with standard mounting, and the mounting style fits common flange patterns without a special adapter plate. Motion can be locked when idle by the standard blocking brake, which holds the shaft when power is removed. That brake function is useful where the axis must remain stationary between cycles or during a power-off stop. Electromagnetic behavior follows the GD winding, which matches the stator impedance to compatible MAC servo amplifiers. The encoder and brake are integrated into the motor housing.
