Product Description:

The MAC090A-0-ZD-4-C/110-B-0/AM164SG servo motor is produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. This model serves as a motor for analog drives, supplying closed-loop velocity and position control to material-handling lines, packaging stations, and other automated equipment that require precise speed regulation during repeated production cycles. Heat is removed by natural convection, so no external blower or liquid circuit is required when adequate airflow is available around the housing. This passive cooling method places the housing surface in direct contact with ambient air, so open clearance around the frame supports continuous operation.

Its mechanical interface uses a centering diameter of 110 mm, which provides concentric alignment to gearboxes or mounting plates and helps the motor seat accurately on the machine face. The motor’s windings use code ZD and are matched to continuous operation at a nominal speed of 1500 rpm. Tachogenerator output is scaled at 3 V/1000 rpm, giving drive electronics a linear velocity signal for legacy analog regulators. Position data can be obtained through an integrated absolute encoder, or the application can rely solely on tachogenerator feedback when separate position information is not required.

In installation, the power leads exit through a connector on side B, simplifying cable routing in cabinets where the shaft faces forward. Because the motor has no blocking brake, stationary holding torque must be supplied by the drive or external mechanics when power is off. The tachogenerator is built to standard quality, providing repeatable voltage symmetry without special calibration. This combination allows the motor to operate with older analog amplifiers while also making position feedback available to systems that read encoder data.
