Product Description:

The GAM2A4003F0CRK3 belongs to the G SANMOTION AC Servo Motors series manufactured by Sanyo Denki. It is a compact rotary actuator with a 40 mm frame, intended for precise position and velocity control in machine tools, pick-and-place heads, and small conveying axes. By converting controller current commands into proportional electromagnetic torque, the motor provides closed-loop motion for tightly regulated industrial automation tasks. The device integrates absolute feedback and a holding brake to secure the axis between operating cycles.

The stator windings use a single-cable architecture connected to a 200 VAC supply, and their phase resistance of 10.9 Ω limits surge current while supporting fast current loops. Continuous mechanical output is 30 W, generated at a rated armature current of 0.65 Arms. Under these conditions, the shaft turns at 3000 rpm and delivers a continuous torque of 0.098 N·m. The motor has a torque constant of 0.183 N·m/Arms, so small current changes produce predictable force. A rotor inertia of 0.0303 × 10⁻⁴ kg·m² and the square 40 mm flange help minimize settling time. These characteristics permit high-gain servo tuning for lightweight loads without requiring a large mounting area.

The motor reaches a maximum speed of 6500 rpm and produces a peak stall torque of 0.37 N·m during abrupt acceleration. Position data are supplied by a battery-free absolute encoder with 23-bit resolution, eliminating battery maintenance while providing precise feedback. The keyway shaft is sealed against lubricant migration, helping protect the bearing area when the motor is coupled to nearby mechanical components. The integrated brake operates at 24 VDC ±10% and draws 0.26 A to hold the axis when motor power is removed. This brake supports stationary load retention during pauses, shutdowns, and other periods when active motor torque is unavailable.
