Product Description:

The GAM2A4005F0XRK1 is a compact AC servo motor produced by Sanyo Denki within the G SANMOTION AC Servo Motors series. It is designed for closed-loop position and velocity control. The motor interfaces with servo amplifiers to drive small actuators, indexing tables, and precision stages used in automated assembly and inspection machines. Its compact form makes it suitable for controlled-motion applications with limited installation space.

The motor delivers a continuous rated output of 50 W at a rated speed of 3000 rpm while producing a rated torque of 0.159 N·m. To sustain that operating point, it draws a rated armature current of 0.79 A RMS from a 200 VAC three-phase supply. The motor has a torque constant of 0.235 N·m/A RMS and a phase resistance of 9.3 Ω, which determine its electrical response to changes in current. A continuous stall torque of 0.167 N·m is available when the shaft is held at zero speed. Thermal performance is supported by a 60.5 mm housing length, which provides a short path for heat transfer from the windings to the case. The 8 mm shaft diameter supports direct coupling to small timing pulleys or clamping hubs without additional bushings.

For transient acceleration, the motor can generate a peak torque of 0.59 N·m by accepting a surge current of 2.9 A RMS, providing enough headroom to overcome inertial loads. The enclosure has an IP67 rating, protecting the stator from dust ingress and temporary water immersion during washdown cleaning. Position feedback comes from a 23-bit battery-free absolute encoder, eliminating periodic battery replacement while providing a single-turn resolution of 8,388,608 counts. The encoder retains origin data through a power loss, which reduces the need for repeated homing sequences after the machine restarts. Its high feedback resolution supports accurate low-speed holding and smooth interpolation, while the available peak torque enables rapid acceleration during short motion cycles.
