Product Description:

The GAM2A4005F0XNK1 is a servo motor produced by Sanyo Denki within the G SANMOTION AC Servo Motors series. As a compact device with a 40 mm frame, it drives small positioning axes, actuators, and index tables in industrial automation applications where space is limited and fast response is required. The unit combines a single-turn absolute encoder with 23-bit resolution, allowing the drive controller to recover the shaft position within one mechanical revolution after a power loss without an additional homing routine.

This model delivers a continuous mechanical output of 50 W while maintaining a rated shaft speed of 3000 rpm. At that operating point, the motor produces a rated torque of 0.159 N·m and draws a phase current of 0.79 Arms. Its torque constant is 0.235 N·m/Arms, allowing the drive to calculate current commands that correspond directly to the required load torque. A stall torque of 0.167 N·m is available for static holding within the motor’s continuous thermal limits. The 200 VAC power requirement is compatible with drive systems used on common three-phase factory power networks. The square 40 mm flange simplifies attachment to miniature gearboxes, while the single-turn feedback system avoids the additional memory components associated with multi-turn position counting.

For rapid acceleration or disturbance rejection, the rotor can reach a maximum speed of 6500 rpm, while the peak stall torque rises to 0.59 N·m for short intervals governed by thermal limits. The phase resistance is 9.3 Ω, which influences current-loop bandwidth and the voltage margin required from the inverter at high speed. An ingress protection rating of IP67 protects the stator windings against dust and temporary water immersion, allowing installation near coolant spray or washdown areas. The sealed housing helps prevent contaminants from reaching internal motor components during operation in packaging, inspection, and semiconductor equipment.
