Product Description:
The R2AA04005FXP00M is a mid-inertia AC servo motor produced by Sanyo Denki for the R SANMOTION Servo Motors series. In automated assembly cells, packaging lines, and semiconductor stages, the unit converts drive current into rotary motion that can be regulated for position, velocity, or torque by a compatible drive controller. Its compact form allows installation in confined spaces, making the motor suitable for axes where space and low moving mass are priorities. The balanced inertia supports responsive acceleration while maintaining stable motion across repetitive operating cycles.
The motor operates from a 200 V supply and provides 50 W of continuous mechanical output. Under nominal conditions, it delivers a rated torque of 0.159 N·m while drawing 0.67 A RMS of armature current. Its torque constant is 0.246 N·m/A RMS, indicating the relationship between commanded current and generated torque. A continuous stall torque of 0.167 N·m allows the shaft to resist modest loads at standstill within the permitted thermal limits. At maximum command, the drive can regulate the motor at speeds up to 6000 rpm, supporting high cycle rates without additional gearing. Electrical losses are moderated by a phase resistance of 9 ohms, and the motor uses standard windings. CE and UL compliance supports integration into machinery intended for multiple markets.
The motor can produce a peak stall torque of 0.59 N·m while drawing a corresponding peak current of 2.8 A RMS, allowing brief bursts of acceleration before thermal limits are reached. If the shaft is blocked, the drive may command 0.69 A RMS of stall current to resist an external disturbance. Position feedback is provided by a battery-backed absolute encoder with a resolution of 131,072 divisions per revolution, preserving position information after the main power supply is removed. The encoder’s high resolution supports accurate positioning and smooth low-speed control. Because the motor has no holding brake, an external mechanical restraint is required when a vertical load must remain stationary without drive torque. The motor has a square 40 mm flange and a mass of 0.39 kg, which reduces the load placed on compact machine structures.
