Product Description:
The GAM2A4003F0XRK0 is an AC servo motor manufactured by Sanyo Denki for the G SANMOTION AC Servo Motors series. With a 40 mm square frame, it fits space-limited machinery that still requires precise speed and position control. Integrated feedback, a low-inertia rotor, and fine torque regulation allow the unit to drive small conveyors, dispensing heads, or vision-guided end effectors where repeatable motion is required in industrial automation.
At the mechanical interface, the motor uses a 40 mm square mounting flange that aligns with compact planetary gearboxes and direct-coupled loads. The power stage accepts a three-phase supply of 200 VAC, and under these conditions, the shaft delivers a continuous torque of 0.098 N·m at a rated speed of 3000 rpm. This combination produces 30 W of output, meeting the needs of light-duty axes such as laboratory pipettors or electronic component feeders. The enclosure has an IP67 protection rating, preventing dust ingress and protecting the housing against temporary submersion during washdown. A smooth shaft without a key or oil seal minimizes axial length and eliminates the maintenance requirements associated with a shaft seal. Its compact mounting arrangement also supports installation in machinery with limited clearance around the driven axis.
The peak stall torque rises to 0.37 N·m, giving the drive enough margin to overcome static friction or momentary overloads without losing synchronization. Position feedback is supplied by a 17-bit batteryless absolute encoder, so multi-turn position data is retained after power is removed without requiring a maintenance battery. Continuous current draw remains at 0.65 Arms, while the torque constant of 0.183 N·m/Arms relates commanded current to developed torque for precise loop tuning. Electrical losses are limited by a phase resistance of 10.9 Ω. The rotor inertia of 0.0233 × 10⁻⁴ kg·m² permits rapid acceleration without requiring excessive drive gain. These dynamic characteristics support fast start-and-stop cycles in compact positioning applications.
