Product Description:
The R2AA08040FCHCW AC servo motor is built by Sanyo Denki as part of the R SANMOTION Servo Motors series. It combines a permanent-magnet synchronous design with closed-loop feedback so a motion controller can regulate velocity and position in industrial robots, indexing tables, and packaging lines. Its flange is compatible with common gearheads, allowing the motor to fit into compact drive stations without a specialized mounting arrangement. An integrated brake secures vertical loads when power is removed, helping prevent unintended shaft movement while the machine is idle.
A single-turn absolute encoder delivers 131072 counts per revolution, allowing fine interpolation of the shaft angle for precise servo control. The mechanical interface follows the DIN 80 frame and has a flange measuring 80 mm, which supports alignment with standard machinery plates. A 24 VDC holding brake keeps the shaft secured during idle cycles, power interruptions, and emergency stops. The power section is rated at 1.0 kVA, indicating the apparent power required from a compatible drive under full torque demand. During high-speed travel, the rotor can reach a maximum speed of 6000 rpm. Multi-turn tracking is not included, so the axis may require homing after an extended loss of power. The motor can operate at a maximum ambient humidity of 90 percent without condensation, making moisture control important in enclosed installations.
The motor uses a medium-inertia rotor, balancing responsive acceleration with stable load coupling in mid-mass gantries and similar motion systems. Its IP67 enclosure protects the stator against dust and temporary water immersion, supporting operation near washdown conveyors and other equipment exposed to moisture. Continuous mechanical output reaches 400 W, making the motor suitable for compact servo axes that require consistent torque without external cooling. The stator windings are designed for a nominal supply of 200 V, so the motor pairs with common 200-volt-class servo drives. Proper inverter selection must account for the motor’s apparent power, peak speed, encoder interface, and brake supply when integrating the unit into a machine. The sealed enclosure and noncondensing humidity limit help protect the winding insulation during routine plant operation and cleaning.
