Product Description:

The MAC090A-0-RD-4-C/110-A-0/WI520LV is an AC servo motor manufactured by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Intended for analog servo drives, the unit supplies tightly regulated torque and speed to indexing tables and pick-and-place gantries. Within an industrial automation cell, it converts amplifier commands into rotary motion so loads can be positioned accurately under changing mechanical resistance. Its four-pole design supports fast dynamic response, which is useful in processes where short cycle times matter.

The motor seats against machine frames with a centering shoulder of 110 mm, so shaft alignment remains repeatable after installation. Heat from copper losses leaves the housing through natural convection, so no external blower or liquid loop is required. Power conductors exit through a connector on side A, which keeps the cable bundle on the same face as the drive enclosure and simplifies routing. Rotor position is reported through tacho feedback and an internal incremental encoder. The feedback system can also include an optional absolute code wheel for applications that need position recall after power is removed, while the tacho channel supports stable speed regulation in analog control loops.

Because the design is supplied without a blocking brake, axes that must hold position at power-off rely on mechanical clamps or gearbox friction. This arrangement suits installations where holding torque is managed elsewhere in the drivetrain rather than inside the motor. The combined feedback signals support amplifiers that use continuous analog commands instead of digital bus communication. That makes the motor suitable for equipment that still depends on established analog control architecture and needs predictable rotary motion during repeated positioning cycles.
