Product Description:

The R2AA04003FXP00M Servo Motor provides medium inertia and excellent features such as rated output of 30 W and an optical absolute encoder. It is the creation of a leading company Sanyo Denki which specializes in precision motion control systems for industrial automation applications. The R2AA04003FXP00M servo motor draw 0.51 arms from the power source when operating at its rated speed and output of 3000 min⁻¹ under normal conditions. This motor is able to achieve 3000 revolutions per minute of speed under normal operating conditions at the rated voltage. The winding of this model has the resistance of 12 ohm which affects how much current flows for a given voltage and impacts the efficiency of the motor. It accelerates and decelerates at a moderate rate and is often used for applications where fast start-stop cycles are required. This R SANMOTION Servo Motor can continuously produce 0.108 N·m at the stall condition without overheating. It comes with an optical encoder with battery backup for position sensing that is used for tracking the position of the motor shaft and provides feedback to the controller. It is capable of delivering 30 watts of power under normal operating conditions which is useful mechanical power.

The R2AA04003FXP00M servo motor has a mass of 0.35 kg that includes its encoder mass as well. When it is not rotating it draws 2.15 arms current at its maximum load which is higher than the rated current because the motor can handle higher currents in short bursts without damage. Its electrical circuits take about 0.55 ms to respond to changes in voltage. Its mechanical system is able to respond to changes in torque by taking only 2.2 ms.
