Product Description:

The MAC090A-0-RD-2-C/110-A-1/S008 is an AC servo motor engineered by Bosch Rexroth Indramat and delivered within the MAC AC Servo Motors series. In automated machinery, this motor converts electrical commands from a drive amplifier into controlled rotary motion, allowing precise positioning or speed regulation on feed axes, gantry systems, or transfer lines. Its design aligns with analog velocity controllers that rely on tachogenerator feedback, making it suitable for legacy motion systems that retain their original control architecture. This makes the motor useful on equipment where stable speed regulation and straightforward integration with existing analog amplifiers are required.

A pilot of 110 mm provides the required centering diameter, allowing the housing to seat tightly in a matching recess and helping minimize runout at the coupling. Heat produced in the stator is removed through natural convection, eliminating the need for external blowers and keeping the installation simple. A spring-applied blocking brake keeps the shaft locked when power is removed, which is useful on vertical axes or when load drift must be prevented. Closed-loop velocity regulation is achieved through integral tacho feedback, enabling the associated drive to measure actual speed directly from the motor shaft.

A sealed power connector is fitted on side A, simplifying cable routing where space behind the motor is limited. The model is classified as a motor for analog drives, so its voltage constants and feedback type match amplifiers that process analog speed commands rather than digital fieldbus traffic. For repeatable velocity measurement, the tacho generator is built to standard tacho quality and supplies a stable DC voltage proportional to rotational speed across the rated range. This arrangement supports integration into established machine platforms that still use separate speed-feedback and power connections.
