Product Description:

The MAC090A-0-ZD-2-C/110-B-1 is an AC servo motor manufactured by Bosch Rexroth Indramat and included in the MAC AC Servo Motors series. Designed as the electromechanical element of an analog drive loop, it translates the drive’s voltage and current commands into controlled rotation for positioning, tracking, or moderate-speed process control. The motor couples directly to gearboxes, pulleys, or ball screws and integrates easily into automated assembly cells, packaging lines, and material handling stations where consistent torque and repeatable motion are required. In automated equipment, it is typically paired with a matched amplifier so commanded motion can be converted into predictable shaft movement under changing load conditions.

Thermal management is handled by natural convection, so airflow around the housing must remain unobstructed to keep winding temperature within limits. For mechanical alignment, the front flange offers a 110 mm centering diameter that matches standard machine-side receptacles and provides concentric mounting. A standard blocking brake is fitted to hold the shaft when the drive is disabled, preventing drift on vertical or overhung loads without external clamps. Base speed capability is 1500 rpm, enabling the connected machine to reach moderate linear or rotary velocities while maintaining high torque at low speeds. Power conductors exit through a connector on side B, allowing cable routing away from the driven axis and simplifying cabinet layout. This routing can also reduce interference around couplings, guards, and other moving machine elements.

Speed information is returned to the amplifier through an integral transducer with tachometer feedback. The 3 V per 1000 rpm signal gives the controller a linear voltage reference across the operating range. Because the feedback remains analog, the drive can regulate speed without relying on a digital encoder channel. Magnetic characteristics follow the ZD winding code, which matches the motor’s voltage constant and current draw to MAC-compatible drive ratings. The overall configuration is cataloged as a motor for analog drives, confirming that its feedback, insulation, and connection scheme align with legacy analog control hardware still used in many production plants.
