Product Description:
The GAM1A4005F0XNK0 is an AC servo motor built by Sanyo Denki within the G SANMOTION AC Servo Motors series. It serves as a compact rotary actuator for industrial automation. The motor converts amplifier current into precise torque and speed for indexing tables, miniature manipulators, and similar motion axes. Its compact format allows it to fit machinery with limited installation space while providing controlled rotary motion for repetitive operating cycles.
It delivers a continuous mechanical output of 0.05 kW at a rated speed of 3000 rpm, producing a rated shaft torque of 0.159 N·m. To sustain this duty, the windings draw 0.81 Arms, while each phase has a resistance of 7.0 Ω. The relationship between current and torque is represented by a torque constant of 0.244 N·m/Arms, allowing the drive to calculate the current needed for the requested torque. The rotor inertia is 0.0153 × 10⁻⁴ kg·m², which supports rapid acceleration without excessive current peaks. The modest operating current also limits resistive heating and allows the motor to operate with an appropriately sized servo amplifier.
For short-term overloads, the motor accepts a peak phase current of 2.9 Arms, producing up to 0.56 N·m of torque for quick starts and transient loads. A square mounting flange measuring 40 mm per side simplifies attachment to compact gearheads. The circular shaft is supplied without a key or oil seal, reducing friction in high-cycle applications. Continuous stall torque is 0.167 N·m, allowing the motor to hold a stationary load within its thermal limits. Position feedback comes from a single-turn absolute encoder, which provides the shaft angle within one mechanical revolution after power is restored. The low rotor inertia supports responsive speed changes, while the standardized flange pattern accommodates compact reducers used in semiconductor tooling and other small automation systems. The absence of an oil seal makes the shaft interface suitable for direct coupling in clean operating areas where additional sealing is unnecessary.
