Product Description:

The MAC090B-0-JD-4-C/110-A-1/WI525LV is a servo motor produced by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. It is designed to deliver closed-loop speed and torque control for analog drive platforms, allowing machine tools, handling axes, and packaging equipment to follow precise motion profiles within industrial automation processes. As a motor for analog drives, it works with current-controlled amplifiers that regulate motion through proportional command signals rather than digital network communication. This type of configuration is commonly used where repeatable speed control and dependable axis response are required without a fully digital drive interface.

The motor mounts through a centering flange measuring 110 mm in diameter, ensuring axial alignment between the shaft and the driven load. Heat generated by the stator windings is removed through natural convection, so no fan or liquid circuit is required and enclosure layout can remain compact around the motor. Power conductors exit the housing through a connector on side A, which helps direct cable runs toward the drive cabinet. Rotor position is returned to the drive by an incremental encoder with standard mounting, allowing the controller to track shaft movement for velocity and phase-angle regulation.

Holding force during power-off states is provided by a standard blocking brake, so vertical or suspended axes remain stationary when the amplifier is disabled. For velocity regulation across a wider speed range, the motor uses tacho feedback with an incremental or absolute encoder, which provides a proportional voltage signal in addition to pulse tracks. Commutation accuracy is maintained by standard tacho quality, which keeps the sensor response suitable for stable control. The motor also uses closed-loop feedback to help the drive react to load changes during motion.
