Product Description:

The MAC090A-0-ZD-3-0/110-A-1 is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It delivers commanded torque and speed to automation axes that rely on analog velocity or current loops, making it suitable for machine tools, material-handling stations, and retrofitted production lines. The motor supports closed-loop motion where the drive adjusts output in response to feedback signals. This operating role makes it useful on equipment that needs stable low-speed behavior and repeatable response to drive commands. Mechanical dimensions follow the MAC family envelope and keep the shaft height and flange geometry consistent with the series.

The electromagnetic package is identified by winding code ZD, which indicates coil resistance and inductance values that let the drive apply rated current without saturation. Under nominal excitation, the rotor reaches 1500 rpm, a base speed that aligns with common 50 Hz and 60 Hz tachogenerator feedback ranges. The integral tachogenerator outputs 3 V/1000 rpm, giving the analog controller a proportional voltage for speed regulation. Heat produced by copper and iron losses is removed through natural convection, so the motor should be installed where ambient airflow is not restricted. Positioning accuracy is aided by a centering diameter of 110 mm, which fits standard locating pilots and keeps the stator concentric with driven mechanics.

The motor has a standard blocking brake, allowing the axis to hold load torque when the drive is disabled. Feedback is supplied with tacho feedback and a second shaft end; the auxiliary shaft permits an external encoder or handwheel without altering motor length. The added shaft end expands feedback or accessory options without changing the main mounting form. Power conductors enter through a connector on side A, simplifying cable routing when the housing is installed against a vertical panel. Classified as a motor for analog drives, the unit interfaces with legacy velocity controllers that rely on ±10 V command signals and tacho return. This arrangement preserves compatibility with existing control hardware that expects analog command and feedback signals.
