Product Description:

The R2AA08075FXP00M is a medium-inertia AC servo motor produced by Sanyo Denki within the R SANMOTION Servo Motors series. It converts drive commands into precise rotary motion for pick-and-place stations, carton erectors, and compact machining cells. An 80 mm square flange simplifies attachment to gearboxes or direct-coupled loads, while a battery-backed absolute encoder retains position through power interruptions and eliminates the need for homing after planned shutdowns. The motor carries CE and UL marks for use in regulated industrial automation environments that require repeatable positioning and dependable operation.

The motor provides a continuous stall torque of 2.55 N·m when its cooling limits are observed. Its rated output of 750 W provides the basis for selecting a compatible drive and protective devices. The windings are designed for a 200 V DC bus, which establishes the back electromotive force range and affects inverter selection. At this voltage, the phases draw a nominal current of 4.6 Arms, which supports proper cable and overcurrent protection selection. A maximum speed of 6000 rpm supports rapid indexing in machines with short cycle times. The rotor inertia of 1.823 × 10⁻⁴ kg·m² balances acceleration response with load stability during repeated bidirectional movement.

Transient motion is supported by a 8.5 N·m peak torque that helps the motor handle sudden load changes without stalling. The torque constant of 0.559 N·m/Arms allows the servo controller to calculate the current required for demanding acceleration and velocity profiles. Fine positioning is supported by the encoder’s 131,072 pulses per revolution with 17-bit resolution, which provides detailed feedback for precise linear movement when the motor is connected to a ball screw or belt drive. The absolute feedback system also preserves the known shaft position when control power is interrupted, provided that the encoder backup supply remains available.
