Product Description:

The MAC090A-0-RD-4-C/110-A-0/WI524LV/S001 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It is intended for closed-loop motion tasks that require precise torque and speed regulation. Typical applications include production machinery, material-handling axes, and general industrial automation systems. Integrated speed and position feedback allows a compatible drive amplifier to monitor shaft motion and correct deviations caused by changing loads.

The motor removes heat through natural convection, so airflow around the housing must remain unobstructed during operation. A centering shoulder of 110 mm aligns the flange with standard mounting faces and helps keep shaft runout within the required tolerance. Power enters the stator windings through a connector on side A, simplifying cable routing when the drive and associated wiring are positioned to the left of the axis. The motor is supplied without a blocking brake, so mechanical clamping or drive-generated torque must secure vertical loads when power is removed. Shaft speed verification uses tacho feedback with an incremental or absolute encoder, providing the analog controller with velocity and position references for smooth regulation. These feedback signals help the controller maintain stable motion during acceleration, steady-speed operation, and controlled deceleration.

For position loops that use discrete count information, the motor can be fitted with an incremental encoder with standard mounting. This encoder connects directly to the drive’s differential input and maintains mechanical alignment across the permitted operating temperature range. A standard tacho quality rating indicates that the tachometer signal meets the ripple and linearity limits expected by compatible analog regulators. As a motor for analog drives, the unit can operate with earlier transconductance amplifiers while supporting encoder-based position control. Its combined velocity and position signals allow the external controller to regulate motion without requiring a separate feedback assembly on the machine axis.
