Product Description:
The GAM2A4005F0XNK2 is a compact servo motor manufactured by Sanyo Denki for its G SANMOTION AC Servo Motors series. It is intended for industrial automation axes that demand accurate velocity and position control, such as semiconductor handlers or miniature pick-and-place actuators. By converting drive inverter commands into regulated shaft rotation, the motor supplies the commanded torque and speed while requiring minimal installation space. Its compact design makes it suitable for small machines with closely arranged motion components.
Under continuous duty, the motor delivers a rated mechanical output of 0.05 kW. That power is produced at a shaft speed of 3000 rpm, allowing direct coupling to small gear stages or timing pulleys without exceeding the rated speed. At the rated operating point, the motor produces 0.159 N·m of torque and draws a line current of 0.80 Arms, which helps with selection of a compatible amplifier. The phase resistance measures 9.3 Ω; this electrical value affects copper losses and the drive voltage required for a given current setpoint. An integrated single-turn absolute encoder reports the rotor position within one mechanical revolution for closed-loop feedback. The shaft has a keyway that provides positive engagement with the connected load.
During acceleration or shock loading, the motor can reach a peak torque of 0.59 N·m while accepting a momentary line current of 2.9 Arms. The rotor inertia is only 0.0324 × 10⁻⁴ kg·m², so the mechanical system responds rapidly to command changes and settles quickly after disturbances. A torque constant of 0.235 N·m/Arms represents the proportional relationship between phase current and developed torque, supporting accurate current control. No oil seal is fitted, so the motor should be installed where fluids are not expected to enter around the shaft. The motor also has no brake, which means the drive or an external mechanism must provide holding force when power is removed.
