Product Description:

The MAC090A-0-ZD-2-C/110-A-0 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Intended for installation alongside analog servo amplifiers, the unit converts voltage commands into controlled torque and speed for indexing tables, pick-and-place arms, and other industrial automation axes. Its MAC-series mechanical platform supports integration into common machine mounting arrangements.

This motor provides a centering diameter of 110 mm, allowing precise pilot engagement with mounting flanges and preserving shaft alignment during load reversals. Thermal energy is removed solely through natural convection, meaning the housing fins keep winding temperatures within limits without auxiliary blowers. The windings support a nominal speed of 1500 rpm, which suits gear stages intended for constant torque at standard operating speeds. Internal coil selection follows code ZD, and this impedance set balances continuous current against developed torque for mid-frame installations. For speed-signal consistency, the motor uses standard tachometer precision, providing repeatable voltage output without specialized calibration.

The rotor is not locked when power is removed because the unit is supplied without a blocking brake, so external clamping or static drive current must be used for vertical axes. Power leads attach through a connector on side A, allowing cables to exit parallel to the mounting surface and remain clear of couplings. As a motor for analog drives, it interfaces directly with Indramat servo amplifiers that use voltage-mode speed loops. Those loops receive information from the built-in tachogenerator, and the sensor assembly is supplied with tachofeedback to support stable regulation in material handling, packaging, and general motion applications.
