Product Description:

The GAM2A4003F0CRK0 is a compact AC servo motor manufactured by Sanyo Denki for the G SANMOTION AC Servo Motors series. With a 40 mm square flange, the unit is intended for semiconductor handlers, desktop robots, and other equipment that demands precise motion in confined spaces. The model integrates a permanent-magnet rotor, a batteryless absolute encoder for multi-turn position data, and a holding brake that secures vertical loads when the drive is disabled. These features allow the motor to provide closed-loop positioning and speed regulation for small-scale automation axes.

When powered from a single-phase 100 VAC supply, the motor produces a rated mechanical output of 30 W while maintaining a shaft speed of 3000 rpm. At this operating point, the drive applies an armature current of 0.65 Arms to generate a nominal torque of 0.098 N·m. The copper winding has a phase resistance of 10.9 Ω, which supports current-loop stability and limits thermal rise under continuous duty. During sustained stall conditions, the electromagnetic design allows a continuous torque of 0.108 N·m, so indexing tables can hold position without external clamping. The 40 mm mounting face follows JIS square-flange conventions, enabling direct attachment to gear reducers or belt pulleys.

The motor can briefly withstand inertial shocks with a peak stall torque of 0.37 N·m. This reserve is paired with a rotor inertia of 0.0303 × 10⁻⁴ kg·m², permitting rapid acceleration without causing overshoot under light loads. Position feedback is delivered by a 23-bit batteryless absolute encoder that retains multi-turn data when control power is removed. An electromagnetic brake energized at 24 VDC draws 0.26 A to clamp the shaft during downtime or an emergency stop. Despite these integrated components, the assembly weighs 0.44 kg, simplifying installation on linear stages and rotary actuators.
