Product Description:

The GAM2A4003F0CNK3 is a small-frame servo motor produced by Sanyo Denki in the G SANMOTION AC Servo Motors series. This unit supplies closed-loop rotary motion for compact automation axes such as semiconductor handlers and miniature pick-and-place modules. It integrates a single-turn absolute encoder so controllers can recover the position immediately after power is restored without performing a homing routine.

Under continuous duty, the motor delivers 0.03 kW of mechanical power while operating at a nominal speed of 3000 rpm. At that operating point, it produces a continuous torque of 0.098 N·m and draws 0.65 A RMS from the drive amplifier, allowing accurate load matching in low-inertia stages. The stator and winding insulation meet thermal class F requirements, so the unit tolerates winding temperatures up to 155 °C without premature aging. An enclosure rating of IP67 provides complete protection against dust and protection against temporary immersion, permitting direct mounting inside washdown tooling. An integrated oil seal works with the enclosure to prevent lubricant from migrating along the shaft during high-pressure cleaning. The body has an overall length of 89 mm, keeping installation depth low when the motor is mounted on machinery with limited space.

The square flange measures 40 mm per side, and the precision-ground shaft has a diameter of 6 mm with an 8 mm keyway length that transfers the load to pulleys or miniature gearheads without slipping. During acceleration, the motor can deliver a peak stall torque of 0.37 N·m, supplying brief bursts that are nearly four times its continuous torque. For vertical axes, a holding brake generates a minimum torque of 0.48 N·m to secure loads when power is removed. The compact proportions help keep reflected inertia low, which supports responsive motion in high-speed positioning stages and simplifies adjustment of the drive control loops.
