Product Description:

The MAC090B-0-ND-4-C/110-B-1/WI639BX is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed as a drive component for closed-loop motion axes, it provides positional and velocity control when connected to analog drive amplifiers in material handling, packaging, and machining cells. Its electromechanical construction delivers responsive operation without the need for gear reduction, allowing the host controller to command direct rotary motion in automated assemblies.

This motor seats against a machine flange using a centering diameter of 110 mm, ensuring concentric alignment with the driven load. Heat from the stator dissipates through natural convection, so no external blower or liquid circuit is required. Power reaches the windings through a connector on side B, simplifying cable routing in cabinets where the shaft faces side A. A standard blocking brake is integrated to hold the shaft during power loss or emergency stops. For feedback, the unit supports tacho feedback and incremental or absolute encoder signals, enabling the drive to measure both speed and revolution count. The unit is specified as a motor for analog drives, so its electrical interfaces match legacy amplifier configurations.

In applications that need finer incremental resolution, the designated feedback line can use an incremental encoder with standard mounting. The brake circuit, encoder, and phase leads are included in the motor interface, so holding, feedback, and power functions remain available through the same motor assembly. This arrangement supports connection to compatible control hardware, keeps cabling paths organized at the machine, and preserves the established mounting format used for this motor configuration. Analog drive systems can use the available feedback paths for speed regulation and monitored axis movement during operation.
