Product Description:

The GAM2A4015V0CRK0 is an AC servo motor manufactured by Sanyo Denki as part of the G SANMOTION AC Servo Motors series. Designed for closed-loop positioning in assembly robots, feeders, and compact gantry stages, this motor translates current commands from a matched drive into accurate shaft motion. The square flange and slender body permit mounting in tight equipment bays, enabling precise speed and torque control without adding excessive mass to movable axes in industrial automation lines.

When energized from a 200 VAC supply, the motor delivers a nominal mechanical output of 150 W. At its rated operating point, the shaft spins at 3000 rpm while producing 0.48 N·m of torque, a combination suited to light inertial loads that must accelerate quickly and settle within milliseconds. For short transients such as rapid indexing, the magnetic circuit can withstand a stall torque of up to 1.7 N·m without demagnetization. The motor has a torque constant of 0.441 N·m/Arms and an associated line current of 1.20 Arms. These electrical characteristics allow a compatible servo drive to regulate current accurately during repeated acceleration and deceleration cycles.

A 23-bit resolution, batteryless absolute encoder is integrated with the rotor, allowing the controller to recover position after a power cycle without a homing routine. Mechanical coupling uses a 40 mm square flange and an 8 mm circular shaft supplied without a key or oil seal, minimizing friction when connected to miniature gearheads. The winding has a phase impedance of 8.0 Ω, which limits inrush and supports stable servo amplifier current control. The motor has a body length of 113 mm, allowing it to fit into compact equipment while providing sufficient space for its winding and feedback assembly. Its shaft arrangement is suitable for clamping couplings that do not require keyed engagement.
