Product Description:

The MAC090A-0-RD-4-C/110-B-0/WI524LV/S001 is an AC servo motor built by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Intended for analog drive systems, it translates current commands from legacy servo amplifiers into rotary motion used on packaging machines, material-handling axes, and light machining centers. The motor’s 90-frame construction offers a balance between torque density and footprint, making it suitable for installations where the available mechanical space is limited. Its compact housing can be integrated into controlled motion axes that require accurate speed and position regulation.

The motor seats on a centering flange that measures 110 mm, allowing precise alignment with gearboxes or mounting plates. Heat produced in the stator is removed by natural convection, eliminating the need for external fans and reducing the number of cooling components around the motor. Power terminals are provided through a connector on side B, so cable routing can follow the machine’s fixed wiring channels without crossing signal lines on side A. Position feedback is supplied by an incremental encoder mounted in standard orientation. This device generates quadrature pulses that the analog drive converts into velocity and position information for closed-loop motion control.

The motor has no holding brake, so static load retention must be provided by drive torque or external clamps when power is removed. Speed consistency is aided by the motor’s standard tacho quality, which provides predictable voltage-to-speed linearity for the drive’s velocity loop. Classified as a motor for analog drives, it remains compatible with older current-loop controllers. The feedback arrangement allows the connected amplifier to detect changes in rotor movement and correct speed deviations during operation. External holding equipment should be used when an axis must remain secured after electrical power is disconnected.
