Product Description:

The GAM1A4005F0CNK0 is an AC servo motor built by Sanyo Denki for the G SANMOTION AC Servo Motors series. This compact rotary actuator is intended for position and velocity control in pick-and-place modules, miniature stages, and other industrial automation axes where limited mounting space and high feedback resolution are desirable. As part of a matched drive system from the manufacturer, it receives three-phase power from a dedicated amplifier and returns absolute position data to the controller, allowing tight closed-loop motion without mechanical slack.

At its continuous operating point, the motor delivers 0.05 kW of mechanical power while turning at a rated speed of 3000 rpm and producing a rated torque of 0.159 N·m. To reach this load point, the windings draw a rated current of 0.81 Arms, and each ampere contributes torque according to a constant of 0.244 N·m/Arms. The stator’s phase resistance is 7.0 Ω, a value that influences copper loss and drive sizing. A small rotor inertia of 0.0218 × 10⁻⁴ kg·m² permits quick acceleration without overshoot. The unit attaches to equipment with a 40 mm square flange, and its overall housing length is 103 mm, so it fits inside compact frames.

Dynamic capability is demonstrated by a peak torque of 0.56 N·m and a maximum permissible speed of 6500 rpm, giving short-term headroom for indexing moves. Position feedback is provided by a single-turn absolute encoder with a resolution of 23 bits, enabling fine command increments without external homing. The motor has an IP67 rating, which prevents dust ingress and allows it to tolerate temporary immersion during washdown. An electromagnetic holding brake is integrated into the motor. It is powered by 24 V DC ±10% and draws 0.26 A to keep the shaft locked when power is removed, simplifying vertical-axis safety circuits.
