Product Description:
The R2AA06020FXW7FE is an AC servo motor produced by Sanyo Denki as part of the R SANMOTION Servo Motors series. Designed for closed-loop motion systems, it combines moderate rotor mass with high magnet flux to deliver precise positioning in assembly stations and electronic packaging lines. The built-in batteryless absolute encoder maintains multi-turn position data when line power is removed, which simplifies maintenance and eliminates the need for homing routines after an outage. This medium-inertia model connects to dedicated amplifiers to provide regulated speed and torque control.
At the nominal operating point, the motor delivers 200 W of mechanical power while generating a continuous torque of 0.637 N·m from a phase current of 1.5 A rms. These ratings are achieved on a 200 V bus, and the motor can reach a maximum speed of 6000 rpm, allowing direct coupling to high-speed lead screws or small timing pulleys. Because no holding brake is installed, axis retention during power loss must be handled by the drive or external clamps. The phase resistance is 2.7 Ω, which affects copper losses and drive sizing during rapid acceleration. A torque constant of 0.476 N·m/A rms links the commanded current to the developed torque, enabling straightforward current-loop calibration.
For short transients, the shaft can produce a peak torque of 2.2 N·m by accepting up to 5.6 A rms from the drive, providing sufficient headroom to overcome breakaway friction or cycle-end impacts. The rotor inertia is 0.222 × 10⁻⁴ kg·m², balancing responsiveness with stability so vibration does not increase during high-gain control. A stall torque of 0.686 N·m indicates the continuous zero-speed holding limit when an external brake is not applied. Mechanical integration is simplified by the 60 mm square flange and a total mass of 0.96 kg. The compact dimensions and low mass allow the motor to be mounted on lightweight aluminum frames without adding excessive load.
