Product Description:

The R2AA08075FXPF6 is an AC servo motor manufactured by Sanyo Denki and offered in the R SANMOTION Servo Motors series. As a medium-frame member of the SanMOTION R family, the unit provides closed-loop shaft rotation for machine tools, pick-and-place actuators, and other precision motion stages. In an automation system, the motor connects to a matching drive that modulates three-phase power and reads encoder feedback, allowing rapid speed changes and accurate position control across repetitive duty cycles.

Its continuous mechanical power output is 750 W, so it can handle medium-duty axes that require less than one kilowatt of shaft power. The stator windings are built for a 200 V nominal supply, matching common servo amplifiers in the 200-volt class. During high-speed operation, the rotor can reach 6000 rpm, providing ample speed capacity for feed drives that must accelerate quickly. A medium-inertia rotor balances responsiveness with straightforward load matching, reducing the risk of oscillation when the motor is coupled to mechanisms with moderate mass. Mounting uses an 80 mm square flange, enabling direct attachment to compatible gearboxes or machine frames without extra adapter plates.

The integrated battery-backed absolute encoder retains the multi-turn shaft position when the main power supply is removed, eliminating the need for homing sequences after controller restarts. Because the motor is supplied without a holding brake, the installation must rely on drive torque or an external clamp to secure vertical loads while the system is powered down. Low-consumption feedback electronics help extend battery life while maintaining the position resolution required by compatible servo drives. The retained position data also allows an automated axis to resume operation from a known mechanical location after a planned shutdown or temporary loss of power. External load-retention equipment should be selected according to the axis orientation, supported mass, and required stopping behavior.
