Product Description:

The MAC090C-1-GD-4-C/110-A-1/WI524LV AC servo motor is produced by Bosch Rexroth Indramat and belongs to the MAC AC Servo Motors series. It is a motor for analog drives that supplies regulated torque and speed to conveyors, pick-and-place heads, and positioning tables in automated production lines. Its mechanical build matches the MAC090 frame class, giving it a direct fit in legacy Rexroth installations that use the same envelope, and it interfaces with classic velocity or torque command cards. This makes it suitable for retrofit machines that still rely on analog servo amplifiers.

The electrical package uses winding code GD, which sets phase characteristics that let the drive module reach nominal current without saturation. Thermal control relies on axial surface cooling; an auxiliary blower powered by AC 230 V pushes air across the housing fins to keep winding temperatures within limits. Precise mechanical centering is achieved with a 110 mm pilot diameter, and the power conductors terminate through a connector on side A, so cables can be routed toward the control cabinet without crossing moving mechanics. This arrangement keeps the cable exit on one side of the housing and leaves the finned surface open to the blower airflow.

Machine safety is supported by a standard blocking brake that locks the shaft when the analog amplifier is de-energized. For motion feedback, the motor is equipped with an incremental encoder with standard mounting, while a tachogenerator supplies real-time velocity information that aligns with the amplifier’s speed loop. This combination gives the analog control system both position-related pulse data and continuous speed feedback during operation. The tacho signal is supplied with standard tacho quality, supporting steady velocity regulation during low-speed running and repeated start-stop cycles.
