Product Description:

The GAM2A4003F0XNK1 is an AC servo motor manufactured by Sanyo Denki within the G SANMOTION AC Servo Motors series. Designed for integrated positioning axes, the unit converts command currents from a digital amplifier into precise torque and speed, enabling consistent motion in electronic assembly lines, laboratory automation, and miniature conveyors. Its square frame and short body permit installation where space is limited, allowing closed-loop rotary control to be integrated without enlarging the machine enclosure.

The motor draws a continuous phase current of 0.65 Arms, which represents the thermal equilibrium limit under rated cooling. At that current, the shaft delivers a continuous stall torque of 0.108 N·m, supporting steady holding or slow-speed feed without overheating. A 40 mm square mounting interface centers the stator on compact machinery while allowing a 6 mm keyed shaft to extend from the front bearing. During normal operation, the rotor runs at a rated speed of 3000 rpm. At rated speed and torque, the motor produces a mechanical output of 0.03 kW. The rated power rate is 4.1 kW/s, and the torque constant is 0.183 N·m/Arms, supporting responsive acceleration with limited current draw. A rotor inertia of 2.33 × 10⁻⁶ kg·m² also supports rapid changes in speed and position.

Transient demands are handled by a peak stall torque of 0.37 N·m, which can be produced when the drive supplies up to 2.3 Arms per phase. The copper windings have a phase resistance of 10.9 Ω, which affects current rise time and drive voltage selection. Under continuous rated conditions, the shaft produces 0.098 N·m, providing a clear operating boundary for closed-loop control. The motor has an overall length of 56.5 mm, allowing it to fit within shallow machine compartments. This compact length preserves installation space in high-density layouts where several motion axes must be positioned close together.
