Product Description:
The GAM2A4003F0XNK3 is an AC servo motor manufactured by Sanyo Denki for the G SANMOTION AC Servo Motors series. Designed for compact positioning axes in pick-and-place units, indexing tables, and micro-machining spindles, the motor converts drive power into precisely regulated rotary motion, while its single-turn absolute encoder provides position feedback. A 40 mm square flange and a total body length of 56.5 mm allow direct mounting in small automation frames, while the shaft keyway supports positive torque transfer. An oil seal helps keep gearbox lubricants contained and prevents contaminants from reaching the bearings.
The motor delivers a continuous mechanical output of 30 W at a rated speed of 3000 rpm. Under these conditions, it produces a rated torque of 0.098 N·m while drawing 0.65 Arms from a three-phase 200 VAC supply. Position data are reported to the drive in approximately 8 million discrete steps because of the encoder’s 23-bit resolution, supporting smooth velocity loops and fine incremental movements. Continuous stall torque reaches 0.108 N·m, allowing the motor to hold modest loads without overheating when the shaft is stationary. The available position data also allow the controller to regulate low-speed movement without relying solely on calculated rotor position.
For short transients, the unit withstands a peak stall torque of 0.37 N·m, providing additional capacity during rapid acceleration or when overcoming static friction. The rotor can reach a maximum speed of 6500 rpm when the application requires higher process throughput, provided that the motor remains within its thermal limits. The winding has a phase resistance of 10.9 Ω, which affects copper loss during operation and assists with current-loop tuning. With a torque constant of 0.183 N·m/Arms, each ampere commanded by the controller produces a predictable increase in shaft torque. This relationship supports accurate torque regulation during changing load conditions and helps the drive maintain stable motion throughout acceleration and deceleration.
