Product Description:

The MAC090A-0-RD-3-C/110-B-0/SA04 is an AC servo motor in the MAC AC Servo Motors series. It converts electrical power into controlled rotary motion for axes that require tight velocity regulation and repeatable positioning. When paired with an analog servo amplifier, the unit drives ball screws, timing-belt pulleys, or gearboxes in assembly lines, gantry robots, or packaging machines, linking mechanical loads directly to the electronic control loop. This operating role suits transfer stations, indexing mechanisms, and similar automated equipment where stable speed response helps the control loop react to changing loads. Its compact frame simplifies installation inside cabinets or on machine sidewalls, which helps reduce the overall footprint.

The mechanical interface uses a centering collar that measures 110 mm, providing a precise pilot for face mounting against gear housings or torque arms. Heat generated in the windings is removed through natural convection, so clear airflow around the housing is required to maintain continuous ratings. The motor is supplied without a blocking brake, so any axial load must be restrained by the drive or an external clamp if input power is lost. Electrical power reaches the stator through a connector on side B, a layout that directs cabling toward the back of the machine and keeps the shaft area clear. That cable direction can simplify routing in installations where the motor face is close to guarding or adjacent components. The electromagnetic circuit is optimized for analog drives, so current and speed are commanded with proportional voltage signals instead of digital fieldbus packets.

Velocity feedback is generated by internal tacho feedback that monitors rotor speed, while the second shaft end remains available for coupling to an external encoder or mechanical load sensor. Signal linearity follows standard tacho quality tolerances, allowing the amplifier to apply accurate proportional-integral control without extensive calibration. This layout keeps the speed feedback function separate from any auxiliary measurement device that may be connected to the rear extension. The unit is manufactured by Bosch Rexroth Indramat, and its connectors, seals, and mounting accessories follow the dimensional and electrical conventions used across MAC motor installations.
