Product Description:

The GAM2A4010F0XRK1 is an AC servo motor produced by Sanyo Denki within the G SANMOTION AC Servo Motors series. Designed for compact motion axes, the unit uses a batteryless absolute encoder to retain position data while power is off without requiring maintenance batteries. Its 40 mm square mounting flange aligns with miniature gearboxes, and an internal oil seal prevents lubricant from migrating toward the encoder. This configuration allows the motor to fit into confined, washdown areas while maintaining accurate position data at startup.

With a continuous current of 0.99 Arms, the motor delivers a mechanical output of 0.10 kW. This output is available at a nominal shaft speed of 3000 rpm, where the corresponding continuous torque reaches 0.318 N·m. The electromagnetic coupling has a torque constant of 0.367 N·m/Arms, allowing the drive current to be directly related to the torque produced by the motor. A phase resistance of 9.0 Ω limits short-circuit current during commutation. The rotor inertia is 0.0600 × 10⁻⁴ kg·m², supporting fast acceleration without excessive overshoot. These electrical characteristics allow compatible servo amplifiers to maintain stable current control during rapid reversals and changing loads.

For brief load transients, the motor can supply a peak stall torque of 1.18 N·m. Velocity commands can be increased up to 6500 rpm when an application requires a higher operating speed. The housing has an ingress protection rating of IP67, making it dust-tight and resistant to temporary water immersion under the applicable test conditions. Despite its sealed housing, the assembly weighs only 0.39 kg, allowing direct installation on lightweight end effectors and compact moving axes. The combination of low mass, high peak torque, and an extended speed range supports responsive operation without requiring a larger motor frame.
