Product Description:

The MAC090C-0-GD-2-C/110-A-1 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. The unit converts electrical input from an analog velocity or torque controller into controlled rotary motion for axes that require moderate power and precise positioning. It is commonly integrated into pick-and-place stations, indexing tables, and light machine-tool spindles where tight speed regulation and repeatable start-stop profiles are necessary in automated production. This operating role makes it suitable for machinery that must respond quickly to changing motion commands while maintaining stable rotational behavior from cycle to cycle.

Internally, the stator uses winding code GD, which identifies the electrical characteristics expected by the matched drive. This winding choice affects torque production and phase-current behavior during acceleration and steady operation. Heat generated during duty cycles is removed through natural convection, eliminating the need for auxiliary blowers or coolant plates. Line power is delivered through a keyed connector mounted on side A, which helps route cables in compact machine layouts. A 110 mm centering diameter supports accurate alignment between the motor and the coupled mechanical assembly. The side-mounted connection also leaves the rear area less congested, which can help when the machine frame offers limited space for cable routing or service access.

The assembly includes a standard blocking brake, allowing the load to remain fixed whenever the supply is shut off. Classified as a motor for analog drives, it operates from continuous reference signals rather than serial fieldbus commands. Speed feedback comes from an integrated tachogenerator and is identified as with tacho feedback, so the controller can monitor shaft speed during operation. Its calibration follows standard tacho quality limits, which support stable velocity feedback for legacy control platforms. The tachogenerator output works well in systems that expect direct analog speed feedback, and the brake helps prevent unwanted drift when the axis is stopped and power is removed.
