Product Description:

The MAC090A-0-RD-2-C/110-A-1/S005 is an AC servo motor engineered by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Classified for analog drives, it converts precise voltage commands into controlled rotational motion for axes that need rapid positioning and stable speed in industrial automation. Typical roles include material transfer stations, basic CNC feeds, and indexing tables where the motor supplies continuous torque while an external controller closes the feedback loop.

This motor has a centering diameter of 110 mm, allowing accurate alignment against machine flanges and helping maintain repeatable shaft concentricity. Heat produced by copper losses is removed through natural convection, so no fans or coolant circuits are required and cabinet layouts stay simple. Integrated tacho feedback delivers an analog speed signal that the drive evaluates in real time, eliminating encoder scaling in the velocity loop. The dimensional and mounting interfaces follow the envelope common to the MAC AC Servo Motors series, allowing installation with compatible frame variants. Guidance from Bosch Rexroth Indramat recommends keeping airflow paths clear around the stator ribs so this passive cooling method remains effective at nominal load.

For holding duties, the motor includes a standard blocking brake, locking the rotor when power is removed to prevent suspended or driven loads from drifting. Three-phase supply conductors terminate at a connector on side A, routing cables parallel to the machine bed and freeing space at the rear. Compatibility with analog drives lets the unit pair with legacy ±10 V controllers, which supports retrofits where digital fieldbuses are not available. The device uses standard tacho quality, meaning the DC tachometer meets baseline linearity and ripple criteria suitable for general-purpose speed regulation without the tighter tolerances used in high-precision spindle systems.
