Product Description:

The MAC090B-0-ND-2-C/130-A-1/S012 is an AC servo motor produced by Bosch Rexroth Indramat in the MAC AC Servo Motors series. Designed to interface with analog velocity and position controllers, the unit converts electrical command signals into precise rotary motion for machinery axes, material-handling stations, and automated tooling. Its electromechanical design focuses on stable torque delivery and feedback compatibility so it can serve as an actuator in closed-loop industrial drive systems. This layout suits applications that need repeatable speed regulation and dependable positioning without a separate digital feedback package.

This model uses a centering pilot of 130 mm, and the large mounting surface aligns the stator housing accurately to adjacent mechanical frames while helping keep shaft runout minimal during coupling. Heat is removed through natural convection, so no external blower or liquid circuit is required, but installation must allow free air circulation around the ribbed housing for steady thermal dissipation. Motion feedback is generated by an internal DC tacho generator with tacho feedback, which delivers an analog voltage proportional to speed for drive regulation. The power leads exit through a sealed connector on side A, establishing a fixed cable route and keeping cable entry consistent with the machine layout.

Because it is a motor for analog drives, the winding voltage constants and tacho output levels match amplifier cards that use continuous current control rather than digital pulse modulation. A standard blocking brake is fitted; it clamps the shaft when supply power is removed and helps prevent uncommanded motion on vertical or high-inertia axes. The feedback stage has standard tacho quality, giving speed ripple low enough for textile, printing, or packaging processes that need consistent web tension. The analog feedback path allows the paired controller to monitor speed continuously during acceleration, steady running, and deceleration.
