Product Description:
The R2AA06040FXH00 servo motor is produced by Sanyo Denki within the R SANMOTION Servo Motors series. This middle-inertia AC unit is intended for precise speed and position control in automated machinery such as pick-and-place heads, compact gantries, and indexing tables. Its 60 mm square flange allows direct connection to compatible reducers or belt pulleys, supporting compact installations without an additional mounting adapter. The motor is designed for use with a matching SANMOTION R amplifier, which regulates current and processes feedback for closed-loop motion control.
The motor delivers a rated mechanical output of 400 W, allowing the shaft to supply this power continuously at the rated operating point without exceeding thermal limits. Under the same conditions, it produces 1.27 N·m of torque while drawing 2.8 A rms from the drive. These values help determine the required amplifier capacity and protective device ratings for the connected axis. The stator is designed for a 200 V supply, making the motor compatible with 200 V-class production equipment. Its torque constant is 0.524 N·m/A rms, allowing the servo controller to estimate generated torque from measured phase current. The middle-inertia rotor balances responsive acceleration with resistance to speed fluctuations during frequent reversals.
The motor provides a continuous stall torque of 1.37 N·m when the shaft is stationary and can momentarily produce a peak torque of 4.8 N·m during acceleration or brief load surges. The drive may supply up to 10.8 A rms during these short peak-demand periods. Its maximum operating speed is 6000 rpm, supporting high linear velocities when the shaft is connected to a low-ratio transmission. Rotor position is measured by an absolute encoder with a resolution of 131,072 positions per revolution (17-bit), providing detailed feedback for precise position and speed regulation. Electrical characteristics include a phase resistance of 1.36 Ω and a back-electromotive-force slope of 18.3 mV/rpm, which current regulators use when calculating voltage demand. The motor is supplied without a holding brake, so an external locking mechanism is required when a load must remain stationary after power is removed.
