Product Description:

The GAM2A4010F0XRK3 is an AC servo motor produced by Sanyo Denki within the G SANMOTION AC Servo Motors series. This unit serves as the rotary actuator in automated equipment, converting commands from a matched amplifier into controlled torque and speed. It is suitable for positioning tables, pick-and-place heads, miniature conveyors, and other compact motion axes. Its small housing supports installation in space-limited assemblies where accurate movement and responsive acceleration are required.

The motor has a rated output of 100 W, a rated speed of 3000 rpm, and a rated torque of 0.318 N·m. It operates from a 200 VAC three-phase power supply and draws 0.99 Arms of armature current at rated load. A batteryless absolute encoder with a resolution of 23 bits is mounted on the rotor, providing high-accuracy position feedback without requiring a backup battery. A phase resistance of 9.0 Ω helps limit inrush during startup, while a torque constant of 0.367 N·m/Arms relates the commanded current to the resulting output torque. The rotor inertia is 0.0600 × 10⁻⁴ kg·m², supporting rapid changes in speed when the motor drives light-duty axes. These electrical and feedback characteristics allow the matched amplifier to regulate position, velocity, and torque during repetitive machine cycles.

Short-duration loads are supported by a peak stall torque of 1.18 N·m, allowing the shaft to hold or overcome static loads during indexing cycles. The motor can reach a maximum speed of 6500 rpm, providing additional speed range for demanding motion profiles. The housing has IP67 ingress protection, preventing dust and temporary water immersion from affecting the internal windings. A keyed output shaft provides positive engagement with pulleys, couplings, or precision gearboxes, while an oil seal helps protect the shaft opening from contaminants and lubricant leakage. The square housing has a flange size of 40 mm, supporting direct attachment to compatible machine plates and compact transmission assemblies. The sealed shaft interface is suitable for equipment exposed to dust, moisture, or occasional fluid contact during normal operation.
