Product Description:

The R2AA2220KBXPG0Y is a servo motor manufactured by Sanyo Denki and delivered as part of the R SANMOTION Servo Motors series. Designed for closed-loop control in automated assembly stations and material-handling cells, the unit converts commanded current from a drive into precisely regulated mechanical rotation while returning high-resolution feedback to the controller. Its architecture targets equipment where repeatable velocity tracking, smooth interpolation, and rapid start-stop sequences are critical to cycle time and product quality. When coupled with a compatible amplifier, the motor serves rotary tables, ball-screw actuators, and indexing conveyors found across semiconductor, packaging, and machine-tool sectors.

An integrated battery-backed absolute encoder preserves shaft position during power loss, eliminating homing routines at startup. Within one revolution, the feedback device delivers 131,072 discrete counts, and across multiple turns, it extends absolute tracking to 65,536 revolutions, supporting long-travel axes without external sensors. The electromagnetic circuit sustains operation at speeds up to 2000 rpm, giving adequate speed headroom for gear-reduced drives that still require high linear throughput. Electrical power is drawn from a 200 V DC bus, matching the rating of standard 200 V servo amplifiers used throughout general-purpose automation.

Mechanical integration is simplified by a square 220 mm flange that aligns with large-frame gearboxes and indexers. Because the motor has no shaft-locking brake, the application must rely on drive torque or external clamps when static holding is needed on vertical axes, during power loss, or during emergency stops. Rotor mass and magnet geometry are tuned for medium-inertia performance, balancing quick acceleration with stable load matching in machines that carry moderate tooling weight.
