Product Description:

The GAM2A4005F0XRK2 is a compact servo motor produced by Sanyo Denki for the G SANMOTION AC Servo Motors series. It provides closed-loop rotary motion for positioning tables, pick-and-place heads, and other automation axes that need repeatable low-power actuation. The model integrates a batteryless absolute encoder so the controller retains shaft position after power cycling without maintenance batteries, simplifying machine design and startup procedures.

A square flange measuring 40 mm on each side establishes the mounting envelope and lets the motor fasten to small gearboxes or direct-drive brackets. Within that frame, the stator can deliver a continuous mechanical output of 50 W when it spins at its rated speed of 3000 rpm. At this operating point, the shaft produces a steady torque of 0.159 N·m while drawing 0.79 Arms from a three-phase bus. The windings are designed for a supply of 200 VAC, so the motor pairs with standard low-voltage amplifiers found in light-duty machines. The phase resistance is 9.3 Ω, while the torque constant is 0.235 N·m/Arms. These electrical characteristics allow the drive to regulate current and calculate the torque needed during acceleration or steady operation.

The built-in feedback device provides 23-bit resolution, giving the controller more than eight million discrete positions per revolution for precise indexing. During rapid acceleration, the rotor can resist stalls at torques up to 0.59 N·m, supplying additional force for overcoming friction or momentary load spikes. The aluminum housing keeps the overall mass to 0.29 kg, reducing the mechanical load placed on compact mounting structures. Rotor inertia is only 0.0324 × 10^-4 kg·m², so the motor can respond rapidly to changing velocity commands. The low inertia also reduces the current needed to reverse direction during repetitive positioning cycles. Its compact housing allows installation in automated equipment where available mounting space is limited.
