Product Description:

The GAM2A4005F0XRK0 is an AC servo motor produced by Sanyo Denki for the G SANMOTION AC Servo Motors series. As a brushless, feedback-controlled rotary actuator, it converts drive commands into precise angular motion for feeders, light conveyors, and small robotic joints. The motor provides stable torque and speed regulation within a compact mounting envelope. Its compact design is suitable for automated equipment where installation space is limited and accurate movement is required.

At its standard operating point, the motor produces a mechanical output of 0.05 kW while the shaft turns at 3000 rpm and delivers 0.159 N·m of torque. This load requires an armature current of 0.79 Arms, which helps with drive module and cable selection. When the axis is commanded to hold its position, the windings can sustain a continuous stall torque of 0.167 N·m without thermal derating. For rapid acceleration or sudden load changes, the electromagnetic circuit tolerates a peak stall torque of 0.59 N·m. This peak capacity enables short bursts of force without a loss of synchronism.

The relationship between current and torque is represented by a torque constant of 0.235 N·m/Arms, allowing the controller to translate torque commands into precise current setpoints. Phase resistance measured at 20 °C is 9.3 Ω, which affects copper losses and drive voltage requirements. Position feedback is supplied by a 23-bit batteryless absolute encoder, eliminating periodic homing and the need for encoder battery maintenance. A 40 mm square flange supports face mounting on compact gearheads, while the circular shaft is supplied without a key or oil seal to minimize length and friction. The rotor inertia is 0.0324 × 10⁻⁴ kg·m², which supports fast reversals in applications requiring frequent directional changes. Operation from a 200 VAC supply makes the motor compatible with commonly used industrial power systems.
